Heating technicians are responsible for installation, maintenance, or repairing home, commercial, or industrial heat systems. They can read blueprints and connect wires. Heating technicians know how to take measurements, cut pipes, connect pipes, and weld as needed. Heating technicians also do routine maintenance work for the purpose of keeping heating systems working in an efficient manner.
During the spring and summer when the weather is warmer, the heating technician may be called on to replace filters or clean ducts. During the winter months when the weather is colder, heating technicians may do work such as adjusting burners or blowers. If the heat system appears to not be working, they might check the burner nozzle, the controls, or the thermostat to diagnose the problem.
For instance, a heating technician may be called in the evening during the winter right after someone's heater has broken down. This is a stressful time for the homeowner because his heater is broken and the house is cold. Heating technicians must be able to cope with that kind of stress and still do an effective job of quickly diagnosing the problem and fixing the heater.
Keep in mind that work hours for a heating technician will vary. For instance, under typical conditions, heating technicians may work 40 hours per week. Work could occur anytime during the day and could occur on weekends as needed. Granted, heating technicians could work more hours per week during winter months because of the extreme necessity to have a heater that works when it is very cold outside.
Home air filtration systems help eliminate pollutants in a home's air. One of the most basic ways to get rid of unwanted materials in the air is to ventilate the house with fresh, outdoor air. When inclement weather or excessive outside contaminants interfere with this method, a home air filtration system can help. Fortunately for those wanting clean air inside the house, there are several products available including: an air purifier, whole house air filters, and a portable air filtration system.
An air purifier is best known for its ability to reduce secondhand smoke, dust, pollen, animal dander, and mold spores. A purifier can help relieve those suffering from allergies and asthma. One of the most popular types is the High Efficiency Particulate Air (HEPA) purifier which is known for filtering even the tiniest particles. Another type is an ion purifier which attracts debris and gathers it onto a surface where one can sweep or vacuum it up. An air purifier can be the perfect size for a small room, or it can be larger and be able to be hooked up to an HVAC unit.
A whole-house air filter is typically built into a home's structure. This type of home air filtration system is able to filter particles in every room, and is often hidden away within the attic, closet, or basement. There are standard models for those who simply want cleaner air, while some types have built-in humidifiers. The upside of the whole house air filter is that it can simultaneously clean air in all rooms, but many experts claim that it is not as effective as smaller units.
Some homeowners prefer to have very clean air in a particular room, which is where the portable home air filtration system comes in handy. Though it can only filter air in one room at a time, it is known for being more effective than a larger unit. This product could be helpful for families with one or two members who suffer from allergies or asthma, as the filter could be placed in their rooms.
Air filters provide a good method for removing dust and pollen from the surrounding air. An indoor air filter is an air-cleaning system that removes harmful particles from the air. These filters are typically used in homes, businesses, and manufacturing facilities that require purification of the air. Most cigar and smoke shops use an indoor air filter. These stores typically allow their customers to smoke tobacco while they are shopping. Using an air cleaner keeps the air fresh and reduces the smell from burning tobacco within the store.
An asthma sufferer typically uses an indoor air filter to help control his asthma symptoms. These products are available in portable units that can easily sit in most bedrooms and office spaces. Having an air filter in the office helps control unwanted dust during working hours.
Most hospitals use advanced indoor air filters in their operating rooms. These systems are designed to remove micro particles from the air. Having an air cleaning system in a hospital reduces the spread of germs and disease, which is essential in that environment.
Air filters systems are also available in most home heating and air conditioning systems. These systems require the connection of an air cleaner on the inlet unit. Many of these units are electrically charged to capture air particles through static electricity. Automotive painting operations require an advanced air filter system. These use manual air filter units in combination with central air cleaners. Automotive paint contains many toxic chemicals. Having a filtration system protects the painters from lung damage and long-term health issues.
While a great deal of attention is given to the quality of the air in outdoor settings, not everyone thinks about indoor air quality. The fact is that the air in a home may be more toxic than the air outside. This is due to a number of different factors that have a negative impact on the quality of the air in houses, apartments, and even commercial buildings.
One of the key factors that influences indoor air quality is the materials used to construct the edifice. A number of materials once used in homes and other buildings have been declared unsafe, due to emissions that are released over time. One example is asbestos. Removing asbestos from inside the walls of older buildings will significantly improve the air quality immediately.
Elevating indoor air quality is often a process of not only eliminating certain contaminants from the building, but also a matter of taking proactive steps to prevent the development of any substance that could have an adverse effect on the quality of the air. This includes cleaning carpeting regularly, repairing leaky water pipes before they can cause mold and mildew, and making sure there is a proper level of ventilation when working with various cleaning or heating agents within the building. Taking the time to learn how to use various substances safely will go a long way in keeping indoor air quality at acceptable levels.
Many countries around the world have set standards aimed at improving the indoor air quality in homes and various types of public buildings. In the United States, the Environmental Protection Agency (EPA) has helped pass legislation that prohibits the use of building materials that could lead to the development of a number of allergies and long term health issues. Air purification systems are now standard equipment in many buildings, helping to limit the production of mold and the transference of emissions such as tobacco smoke to furniture upholstery and into air ductwork.
It often seems that we've no sooner finished cleaning dust from our homes when it starts to settle once again. No one wants a house full of dust. In addition to being unsightly, it also contributes to uncomfortable situations such as asthma and allergies.
If you'd like your house as dust free as possible, simple surface cleaning isn't going to do the trick. Dust doesn't only rest on visible surfaces. It embeds itself in fibers and and builds up into bunnies under the bed. Your job is to identify all the places it hides in your home and deal with them accordingly.
An air filter or purifier will help to remove airborne dust particles from the air. There are models in all sizes and price ranges so you should have no problem finding one that best suits your situation.
When cleaning surfaces such as table tops and shelves, try wearing gloves instead of using a cloth or rag. This will keep fingerprints off the surface and enable you to get into crevices a little easier. If you spray furniture polish on gloves or a cloth, it will enable you to clean more easily. A dryer sheet makes a wonderful dust cloth, using one will not only pick up dust, it will eliminate static making it harder for particles to adhere to the surface.
Thermostats are connected to a heating and/or air conditioning unit and are used to control and regulate the temperature inside a building by automatically turning the unit on and off as needed. Many single unit heater and air conditioners have a built-in thermostat that can be used to regulate the unit.
A central heating and/or air conditioning unit will have a thermostat attached to the unit by wires, but located in a different area of the building for the convenience of the user. Replacing a thermostat can be easily done; it requires safety, time and an understanding of thermostat wiring.
Before beginning any thermostat wiring project, it is important to read through the entire set of directions and carefully study the diagram. Any necessary equipment should be purchased and all of the supplies gathered. Before even taking the old thermostat off of the wall mount the power source to the heating and/or air conditioning unit must be shut off. Turing the power off will prevent any injury to the installer or damage to the thermostat or the unit. Due to the fact that this step is so vital, a double check should be made by turning the unit to the on position to see if it comes on.
Since the old thermostat wiring may have different thermostat wire colors, it is advised to mark and label each wire as it is disconnected from the old unit. A simple tip to do this is to wrap each wire with a piece of masking tape and then label the masking tape. This will make it easier when wiring in a new thermostat. Note that thermostat wiring is not a quick process and in order to be sure that it is done correctly, time must be taken to ensure that all of the thermostat wire colors match up.
Overvoltage is a condition in which voltage is higher than the level that the object is rated for. The term overvoltage is most often used to refer to voltage conditions in power lines, indicating conditions when too much voltage is traveling through a power system. It can also apply to electric-powered objects like computers to indicate that the voltage supplied to the object is greater than that for which the object is rated. For an electric company, overvoltage is sometimes used to describe a persistent level of voltage over the range designated for the power line, a problem condition that can affect electronics and energy efficiency in all buildings connected to the malfunctioning power line area.
The most damaging overvoltages are caused by an oversupply in electricity like those experienced when lighting strikes somewhere in a power grid. When overvoltages are caused by lightning strikes, the power can range in the hundreds of kilovolts (kV), high-voltage power levels that can blow fuses and damage more sensitive electrical equipment. These high voltage conditions can take out electrical equipment and cause blackouts in the surrounding areas.
Overvoltage due to lightning is one of the most common natural causes of power interruptions. They can also be caused by a sudden drop in power use, like if a large, power-sucking appliance such as a central air conditioning unit is suddenly powered off or if an ear-splitting rock band suddenly shuts off its equipment all at once.
Delicate equipment that can be damaged by high voltage surges usually benefits from protection against power changes. Systems that provide overvoltage protection can also be called voltage optimization systems. The most common type of overvoltage protection is a surge protector, which generally is a strip of outlets that plugs into a wall. The surge protector has circuits that provide protection against overvoltage for the electric objects plugged into the surge protector. Advanced surge protectors condition power for delicate electronic devices, changing it so it provides optimum electric properties.
Attic ventilation fans are devices that help to move hot air out of an attic space, effectively lowering the temperature of the area directly under the roof of a building. Fans of this type can also be helpful in minimizing attic moisture, particularly in humid weather. In some climates, an attic ventilator fan can even be used to cool the entire home without the use of a central air conditioning system.
There are three different types of attic ventilation fans that are in common use. One option is a simple turbine-style fan that uses wind power to manage attic ventilation. Fans of this type are often situated directly under the eaves of the structure. There is no power source other than the wind, a fact that renders this particular type of fan relatively useless in climates where there is little air movement. Still, the generation of heat in an attic will tend to cause the blades of the fan to turn enough to expel at least a portion of the hot air from the attic space.
This means that the designs that come with only solar panels will not function to full capacity when there is no direct sunlight. Installing a model that has a storage battery will make it possible to keep the fan working at peak efficiency even at night, a big advantage in locations dealing with tropical temperatures.
In addition to reducing the overall temperature in the attic, high-quality attic ventilation fans can also minimize the development of attic mold. This attribute is especially important in areas where humidity levels tend to be high during the summer months. Less mold in the attic means a lower chance of the mold spreading into the walls and reaching other parts of the home. Limiting the development of mold also minimizes the risk of triggering allergies or causing respiratory problems for anyone living in the home.
A temperature control system is a programmable thermostat that can keep the home or office at a desired temperature regardless of fluctuating exterior conditions. The advantage of having such a system over a common thermostat is that it can save energy and money by automatically maintaining different temperatures at different times of the day and night.
This type of system consists of a small digital device, wired to a heating and cooling system. About the size of a traditional wall-mounted thermostat, a temperature control system contains a circuit board and memory chip. After setting the system to a desired temperature, known as a set point, the system will utilize the heater or air conditioning as needed to maintain that setting for the duration programmed.
Though these systems are extremely affordable, the least expensive models may not have the added flexibility of the more deluxe models. For instance, an economy model might not have the ability to set weekday controls separately. Whatever schedule is set will apply for the entire workweek. Deluxe models allow the user to apply unique set points to each day of the week, while most models allow different schedules for Saturday and Sunday.
If you do not have air conditioning, a temperature control system can still be connected to your heater for programmable heating. Highly convenient and money-saving systems are available online and at your local home improvement store.
Heating, ventilation, and air conditioning (HVAC) systems rely on a network of metal ducts to distribute air throughout a building. These ducts consist of sheet metal channels that extend from a central furnace or air conditioner to each of the occupied rooms or living areas within the structure. Traditional ductwork featured a square or rectangular shape, which allows installers to maximize available space within a ceiling or wall cavity. Round ductwork presents an effective and efficient alternative to traditional rectangular ducts, and may be the most cost-effective option in a variety of building applications.
Round ductwork consists of round or cylindrical lengths of duct that can range from short sections to several feet or meters in length. It generally also includes the fittings and transition pieces required to install a complete system of round ductwork. This includes tee-transitions, elbows, and other joints where the ducts are required to travel around a corner or obstruction. It may also include dampers, vents, and outlets used along the ends of these ducts as they enter a room.
Many builders and HVAC installers rely on special charts that enable them to transfer between traditional rectangular ducts and round ductwork. These charts are provided by manufacturers and can often be found in textbooks and industry publications. Generally, a specific size of rectangular duct equates to a specific size of round ductwork in terms of airflow. By determining the required airflow to each space, installers can refer to these charts to help them choose the correct duct size.
The airflow created by each duct size is a function of the material of the duct, air pressure within the system, and the speed at which the air leaves the central furnace or air conditioner.
Smoke dampers are a type of building material used to prevent smoke from spreading throughout the structure during a fire. Contractors install these dampers in HVAC ducts to block the flow of smoke in heating, ventilation, or air conditioning systems. Smoke dampers represent a critical part of the life safety system within a building. Many building codes require these dampers to help save lives and reduce injury during a fire. Some building owners or homeowners may also use smoke dampers on a voluntary basis to improve safety for occupants and residents.
A smoke damper fits tightly within an HVAC duct and is designed to allow air to flow freely under normal conditions. When smoke is present, smoke detectors send a signal to an actuator in the damper, causing it to shut off air flow through the duct. Some systems may also include manual dampers, which can be opened or closed using a switch on the outside of each duct. Others allow operators to push a single central button to shut all dampers at once during an emergency.
Different types of smoke dampers utilize a variety of operating mechanisms to stop the flow of smoke and air. Gate-style smoke dampers feature a metal gate or door that drops down to seal off the duct. Baffle units feature vents, or baffles, that close off the duct as needed. Rotational units include a central plate that runs perpendicular to the duct under standard conditions, but rotates to completely close off the duct during a fire.
One of the primary advantages associated with smoke dampers is their ability to save lives during a fire. By slowing or stopping the spread of smoke, they give occupants more time to exit the building while reducing smoke exposure. By limiting smoke exposure, dampers help to minimize smoke-related injuries and keep people conscious and alert.
There are different methods of ductwork installation driven by the types of heating/cooling plants in homes as well as by design layouts. Ductwork designs are extended plenum, radiant piping or a combination of these. Some run through a ceiling instead of an attic, and others run through a crawlspace or basement, but all designs have their base in the furnace placement.
Many localities have energy-efficiency codes, and ductwork installations must meet these standards. Newer duct materials have changed some methods, and experimental prototypes for hot/humid climate home construction have led to further innovations from the old tried-and-true ductwork installation plans.
The ductwork installations for gas air furnaces are specific to safety concerns when using gas. For safety, all components and fittings of ductwork for a gas air furnace system must meet performance temperature ratings, as well as smoke development and flame spreading ratings. Some residences and light commercial buildings have ductwork installation designs with the ductwork on the outside of the building. Inside installations need only insulation wraps, but outside installations need water-resistant sealant and weather protectant applied as well.
There are standards for the installation of electrical central heating, ventilation and air conditioning (HVAC) systems. These ductwork installations must have no leaks and a balance between the supply air and the return air. There should be no loss of airflow velocity because of crimping, improper sizing or bends too closely set to extended plenums.
There are many different types of thermostats available for home central air and heating (HVAC) systems. Each type of central heating thermostat performs the same basic function: regulating the inside temperature of the home. Optional functions vary by thermostat model and include the ability to program different temperatures for different times, control over multiple heating and cooling systems, and remote access to thermostat controls. To choose the best thermostat for your needs, consider which optional features you will be most likely to use.
A basic central heating thermostat is best for households that want to maintain a constant temperature in the home at all times. These units allow you to adjust the temperature and turn the central heating system on and off. Some models feature digital displays with buttons to adjust the temperature setting, while others use simple dial or slider controls.
If there are times when no one is in your home, a central heating thermostat that you can program by the hour may be your best choice. With this type of HVAC thermostat, you can program a lower temperature setting for the times when the house will be empty, which can save money on your monthly electric bill. Program the thermostat to return to your preferred temperature about an hour before you return so that the house is warmed back up without a wait.
You may program these thermostats by the day or for up to seven days at a time. Various models allow you to choose between options such as setting different temperatures seven days in a row; setting different temperatures for weekdays and weekends; and setting different temperatures for Monday through Friday, Saturday and Sunday.
There are different methods of ductwork installation driven by the types of heating/cooling plants in homes as well as by design layouts. Ductwork designs are extended plenum, radiant piping or a combination of these.

Newer duct materials have changed some methods, and experimental prototypes for hot/humid climate home construction have led to further innovations from the old tried-and-true ductwork installation plans.
Additionally, there is semi-rigid flex piping that can be run individually to each room, and there are claims that it diffuses noise pollution in the home. Further, these semi-rigid pipes have been tested and proven to deliver better air quality over time, extracting damp air in humid climates and not allowing dust to settle and trap mold.
A newer type of ductwork installation design has been tested and found to be a considerable improvement over any other ductwork installation design for use in humid and hot climates. Making use of specific calculations, these designs make use of running ductwork in the interior of the home under the ceiling plane at a much lower cost and produce zero-energy homes. There can be no duct leakage to the outside, and conducive gains/losses are eliminated because there is no heat buildup in an attic for the ductwork to have to deal with, so the set point temperatures remain nearly constant in the ducts. These designs also make use of transoms in each room to promote good airflow to returns.
A ductless air conditioner is an air conditioning system that allows homeowners to enjoy the benefits of cooled air without the high cost of duct work. They are an affordable alternative to central heating, ventilating, and air conditioning (HVAC) systems, which rely on an extensive network of ducts to move air. Ductless air conditioners are considered to be more efficient and easier to maintain than window-mounted units.
Often called a “split system,” a ductless air conditioner is made up of two parts. There is a compressor, which is placed outside of the home, and a fan, which is installed in the room that is to be cooled. The fan can be wall-mounted, concealed in a drop ceiling, or set on the floor. The two units are connected using piping or conduit. The conduit contains lines for refrigerant, condensate, and electricity to run the unit.
Another major benefit to using a split system air conditioner is the high level of energy efficiency associated with these units. Cool air is directed to the room where it is needed instead of all over the house. There is no issue of air leaks, which are common when cooled air travels through duct systems. The entire system can be controlled by a thermostat, so that the temperature in the room is kept exactly where it is set by the homeowner.
The main benefit of a ductless air conditioner is that it allows homeowners to save on the high cost of adding ductwork, which often involves tearing down walls or ceilings. This is particularly useful in older homes that have no central duct system. Many people also rely on ductless air conditioners to cool home additions, including sun rooms or garages.
HVAC stands for heating, ventilation, and air conditioning. Ventilation is part of the process of heating or cooling air, which creates comfortable temperatures in a space. Air must be moved to and from a heating or cooling unit. Heated or cooled air, also known as conditioned air, is then moved out to the living or working space. This is done through the use of a ventilation duct. As the conditioned air is delivered, an equivalent amount of air must then be moved to the unit once again so it too can be conditioned.
While many homes today are built airtight for greater energy efficiency, the ventilation process helps substitute fresh air for stale air, which is then exhausted from the space. Both can occur by way of ventilation ducts. Some HVAC systems, often in commercial environments, allow the same air to be recycled or reconditioned. This is simply transferred air and not recommended. Too many pollutants can contaminate air and diminish oxygen, requiring another method of ventilation or air purification to obtain and maintain optimal air quality.
Such systems may employ intermittent ventilation, which means certain high-risk areas are ventilated quickly to remove contaminants or even moisture. A good example is the use of an exhaust fan. However, in many residential settings, continuous or central ventilation is preferred. Continuous ventilation is simply the process in which stale air is replaced with fresh air on a slow yet steady basis.
The ventilation duct system is generally designed in a way that allows for the most efficient delivery of fresh air to the system and conditioned air to the receiving spaces. The less air has to travel, the less likely it is to lose temperature or to be contaminated. A ventilation duct, or parts of it, may be made from rigid or flexible material. Flexible parts of the ventilation duct are generally smaller lengths, frequently used to conveniently attach rigid ductwork to the system. Flexible materials may also be used in other difficult to manipulate spaces.
The basic function of an air conditioning thermostat is to turn the cooling unit on and off at a preset temperature. Choosing the best air conditioning thermostat depends largely upon your own individual needs, lifestyle, and energy consciousness. Air conditioning thermostats are available in several different styles from basic manually operated models to multifunction programmable types. A simple manually operated air conditioning thermostat works best if you prefer to keep the indoor air temperature at a constant level at all times. Programmable thermostats are a better choice if you are away from home for several hours each day and want to save energy.
In its simplest form, an air conditioning thermostat is a temperature activated device that automatically controls the operation of the cooling unit. The purpose of this device is to maintain a constant indoor air temperature in a home or building. A manually operated model is usually sufficient for this purpose. Many people prefer to raise the air temperature when the home or building is unoccupied to conserve energy or save on cooling costs.
A manually operated air conditioning thermostat can easily be set to a higher temperature when leaving the home or building each day, but you may find that the air is too warm upon returning. You may also forget to make the necessary temperature adjustment before leaving for the day. A programmable thermostat is usually more suitable than a manual model if you wish to make daily temperature adjustments. It can be set to raise the temperature automatically when you leave and lower it shortly before you return. This function conserves energy during unoccupied times and returns the temperature to a comfortable level when or before you return.
In addition to raising the air temperature during unoccupied hours, you may also want to adjust it at night while you sleep. Many programmable thermostats are capable of storing multiple settings for both daytime and nighttime hours. A slightly warmer air temperature can be selected during sleeping hours and automatically lowered again before you awake. Some programmable thermostats can also distinguish between days of the week so that different settings are observed on weekends. These models sometimes allow you to override the regular settings if you come home early or for special occasions such as holidays.
Room air conditioning, also known as window air conditioning, is a good alternative to central air conditioning for renters who live in older homes or those who have only a small space to cool. Additionally, even though they cost more to operate, room air conditioning units are attractive to those on a tight budget because they have a lower up-front cost. Room air conditioning units can be purchased for as little as $200-$300 US Dollars (USD), while central air conditioning systems cost thousands of dollars to install.
Window air conditioner units can be purchased at any home improvement store. Although it's natural to assume that bigger is always better, many people make the mistake of purchasing air conditioning units that are too large. If the unit you choose is too large, it will cycle on and off more often than necessary. This will wear down the machine faster and result in a higher energy bill for you.
To determine what size of air conditioner you need, look at the size of the area to be cooled. For small rooms of 100 to 150 square feet (30.48 to 45.72 square meters), 5,000 Btu's is sufficient. For a studio apartment of 900 to 1,000 square feet (274.32 to 304.8 square meters), however, you'll need a high-powered unit with 18,000 Btu's.
When looking for room air conditioning units, consider purchasing a product that is ENERGY STAR® qualified as having met the guidelines set by the US Environmental Protection Agency and the US Department of Energy. These products use 10 percent less energy than conventional room air conditioning units and often include features such as timers that allow for better temperature control when you're away from your home during the day. In this way, ENERGY STAR® products help prevent global warming while saving you money on your home cooling costs.
Indoor air conditioners are systems or units that help to regulate the internal temperature and humidity of a room. Air conditioners are also sometimes used to increase indoor air quality as this can have an effect on the health of people who use the building. Some examples of indoor air conditioners include portable air conditioners, central air conditioners and window-mounted air conditioners.
Portable indoor air conditioners are usually used in small rooms or locations that don’t require temperature regulation on a regular basis. For example, in countries where temperatures rarely become uncomfortably hot, a portable air conditioner may be the best solution because it doesn’t require any installation. Portable units are often placed on rollers in a room and require a hose or vent that connects the conditioner to the outside in order to remove heat. These units come in a variety of power levels to suite the needs of a particular room size.
Another consideration is how many rooms need to be air conditioned. A portable air conditioner will usually not be powerful enough to cool more than one room. Central air conditioning systems can be much more powerful.
There are several reasons why indoor air conditioners are important for offices and homes. The most obvious is that above a certain temperature a building becomes uncomfortable to occupy for long periods of time. This can reduce the effectiveness of workers or the comfort of those living there. Air conditioning units can also help the quality of air that workers breathe, which is important for health.
Mobile air conditioning is a term that is used to describe home air conditioning systems that are easily detached and stored when they are not needed to keep the home comfortable. These types of air conditioning units are usually somewhat small in size and will set on a flat surface somewhere within a room or hallway. Unlike central air conditioning or even window air conditioners, the mobile units make use of expandable plastic ducts in order to vent warmer air from the space.
As a room air conditioning option, a mobile air conditioning unit is normally the size of a small end table and is relatively lightweight. For the most part, systems of this type are intended to cool a single room, although some models are equipped to cool larger spaces. While a system of this type is usually considered to be a form of ductless air conditioning, most mobile units do require some means of venting air to the outside. This is usually accomplished with the aid of plastic ductwork that can be attached to the device on one end while the other end is ran out a nearby window.
Still, mobile air conditioning can be extremely helpful in a number of situations. The mobile units are ideal for use at lake cabins and other weekend getaways when the temperature and humidity begin to rise. Some people keep a mobile air conditioner on hand in the event that the home’s central air system fails for some reason. Since the purpose of the units is usually to offer temporary relief from humidity and heat, the awkwardness of the units setting in a room can be overlooked for the short term.
Many home stores and hardware stores will carry at least one or two different sizes of mobile air conditioning units. As with window units, it is possible to purchase relatively small units that will adequately cool a small space or larger units that can keep a larger and more open room comfortable even in high temperatures. While mobile units tend to cost a little more than window units, they are an ideal backup system and much easier to store when not in use.
Static pressure is the pressure that is exerted by a liquid or gas, such as water or air. Specifically, it is the pressure measured when the liquid or gas is still, or at rest. Several different industrial and scientific applications exist for this term, but most have to do with air pressure rather than water pressure. In aviation, for example, a static pressure system is how a plane's altimeter and airspeed indicator operate. In construction, it refers to the pressure that a fan must exert in a ventilation system in order to cause air to flow.
The concept is also an essential one in the science of fluid mechanics. Scientifically, static is distinguished from dynamic pressure, both of which are components of a system's total pressure. This relationship is defined in Bernoulli's equation, and relates to the study of the flow and motion of fluids. The principle of Bernoulli's equation is that static pressure and dynamic pressure may vary greatly in different areas of a fluid in motion, but the total pressure remains constant.
One of the more important areas where an accurate understanding of this type of pressure is important is in the field of aviation. The goal of a plane's altimeter is to measure the air pressure at the height at which it is flying, to determine the altitude. The way this is done is through a small opening in the outside of the aircraft, called the static port.
Unfortunately, no matter where the static port is placed, it will always read an air pressure that is at least slightly different from the local static air pressure at that altitude. This is true whenever the plane is in motion in the air. To attempt to overcome this error, the static port must be placed very carefully by the designer of the aircraft. A well-placed static port will minimize the discrepancy, known as the position error.
Sound traps are devices used to help absorb or muffle the sound generated within a heating ventilating and air conditioning or HVAC unit. The purpose of the sound trap is to minimize the amount of sound that travels through the ductwork, usually by projecting the sound back toward the point of origin. This approach helps to keep the interior areas in which the ductwork opens into different rooms relatively quiet and free of the roar that would otherwise come through the vents whenever the system was in operation.
One of the most simplistic designs for a sound trap is the insertion of what is known as an offset into the ductwork itself. Typically, the offset is composed of materials that are capable of absorbing and deflecting sound in a specific direction. It is not unusual for duct sound traps to be placed at several strategic locations throughout the system, beginning with one near the connecting point for the ductwork and the HVAC equipment. Other traps are placed at different points in the ducts, with the number varying based on the amount of ductwork required to adequately heat and cool the interior space.
A sound trap network in a commercial building would be somewhat more complex, especially if additional heat pumps are necessary to provide adequate temperature and humidity control to a number of stories in the building. Professionals can assess the size and type of equipment needed to maintain the proper temperature within the space, design the layout of the duct system, and determine how many AC soundtraps would be necessary to keep the system relatively quiet during operation.
Replacing a sound trap is normally a simple task. The duct is opened at or near the location of the trap and the device is removed. A new device is moved into position and secured in place, with care taken to make sure the new sound trap will not work loose after repeated buffeting from vibrations and air flow from the heat pump. While easy to replace, many systems can go for years without the need to switch traps, with some lasting longer than the heat pumps themselves.
HVAC training from an accredited school is mandatory for anyone who wants to work in the heating, ventilation and air conditioning (HVAC) industry. There are three primary sources of HVAC training: community or technical colleges, apprenticeship programs or vendor specific training. HVAC systems are found in the residential and commercial building sectors and are used to circulate air and provide a comfortable temperature. There is a huge variety in the types of systems used, depending on the environment, space and building type.
HVAC training provided by community or technical colleges can be divided into two types: technician and mechanic. An HVAC technician program is one to two years in length, and a mechanic program is three to four years long. The primary difference between the two programs is the depth of technical expertise acquired.
HVAC equipment is extremely complex, and many vendors provide HVAC training programs to certified HVAC mechanics and technicians. These courses usually last one to three days, and they often are arranged by the local HVAC trade association.
This type of specialized training is very beneficial to both the vendor and the mechanic, and many are offered for free. This is especially true if the company is trying to expand its market share in a particular area, because it can be a great way to increase sales.
HVAC, or heating, ventilation, and air-conditioning, refers to those mechanical systems and products within a home or business that achieve heating and cooling. HVAC products include furnaces and air conditioners, as well as the ducts that guide air flow, the vents that inhale and expel air into the mechanical systems, and the filters that catch small air particles as the air passes through. Choosing the best HVAC products involves a combination of performance preference, budget, and consumer research.
Obviously the easiest way to choose HVAC products is to ask any HVAC company what they recommend. The downside of this method is that you would get almost as many answers as companies you contact. Many heating and air conditioning contractors sell specific brand name products and may only deal in one or two brands. This is where consumer research comes in. By researching brands using resources like Consumer Reports, retailer websites, and consumer forums, you can get an idea of each brand’s mechanical reliability, performance efficiency, and warranty information.
When replacing a furnace or air conditioning unit, make sure that your salesperson makes a thorough observation of your home or business’s existing system, the square footage, and current configuration of ductwork and vents. HVAC products are manufactured with different specifications for different environments. You don’t want to purchase a unit too small for the space or conversely, one that is unnecessarily large. A good company will give a proper evaluation of your heating and cooling needs, as well as assess whether you need additional components like a humidifier or air purifier in conjunction with your new system.
When you have chosen an HVAC product that is suitable for your structure and budget, be sure to ask about the required routine maintenance such as cleaning, changing filters, and seasonal tune-ups. Make sure you know which filters are best and follow the recommended maintenance schedule to get the most life and best performance out of your system. Also make sure to not perform any maintenance that would subsequently void the product’s warranty.
An air return duct is an integral part of nearly all heating, ventilating and air conditioning (HVAC) systems. Generally, HVAC systems use a forced air process that blows either heat or air conditioning through ductwork into a home or business. An air return duct usually is located either in a hallway or in the ceiling, and its purpose is to extract air from a room and recycle it through the system to further condition it by cooling or heating.
Most central air and heat systems have a condenser that is outdoors and a coil that is located indoors that allows one unit to both heat and cool a building. In the summer, the return duct removes warm air from inside and transports it to the outside through ductwork to be conditioned.
Ductwork is a sealed system that usually is located in the attic for structures with slabs or under the floors on structures that are raised off the ground. The purpose of a ducts is to give air a passage through which it can flow to reach the outdoor components, undergo the conditioning process, and return to the building. Once back in the building, the air usually is distributed by a fan through registers into the rooms.
HVAC systems typically use a refrigerant to cool the air by carrying the heat outside to the condenser. The compressor in the outside unit compresses the refrigerant into a high-pressure gas. Once the gas travels through the coil outdoors, it loses heat and transforms into a liquid. It then enters the evaporator coil and expands into a low-temperature gas to absorb heat that enters into the system from the air return duct. This process repeats itself until the temperature that is set on the thermostat is reached.
At the time it happens, it may seem like nothing is worse than having the heat conk out in the dead of winter, or the air conditioning stop working on the hottest day of the year. Heating ventilation and air conditioning (HVAC) systems are expensive, so when things go bad, many homeowners are hesitant to dish out more money for repairs. Fortunately, there are many tips for HVAC troubleshooting that may allow a “do it yourself” fix.
One side note: although HVAC troubleshooting is a cost effective and sometimes a better choice for homeowners, major repairs should not be attempted by non-professionals. This could result in serious damage to equipment, leading to pricier repairs or even having to replace the entire system. Additionally, even simple repairs are completed at the risk of the homeowner. If you want to be cautious, hire a professional.
Additionally, it is important to properly maintain a system in order to ensure proper function and proactively prevent future problems. Filters must be replaced regularly and air vents should be cleaned to remove any dust or dirt. Make sure no vents are being blocked by furniture or other items, and open them wide to allow proper air flow.
Most HVAC repairs will need to be handled by a licensed HVAC technician. Homeowners may be able to make minor adjustments as well as help target the root of the problem ahead of time to cut down on labor hours once a technician is called. HVAC diagnostic software is available for home use, and can really cut down on service calls if the problem is something minor and needs only slight adjustment. The local HVAC technician should have more information about this software.
To find the best HVAC companies in your area, it is a good idea to first collect the names and numbers of each business and contact them by phone. This information can be found online or through the local phone directory. You may also want to make out a list of questions beforehand, and have it handy when you make each call.
Questions to ask HVAC companies include whether or not they take your kind of project, what the price ranges are, what general turnaround times are, and whether they have reliable references. A good company will be more than willing to answer these questions, and any additional ones you may have. If any of them seem hesitant or unsure of how to answer, move on.
After you’ve narrowed down the list of potential HVAC companies you may consider hiring, invite them each to come to the building where the work will be done. This will allow them to inspect any current ductwork and systems that are in place, as well as take a look at the working environment for potential issues. They should be able to give you a more accurate price quote at that time so you can make a decision that is within your budget.
If you get references from a company, be sure to follow through on them. Former clients will be more than happy to give you the inside story on what it’s like to work with a company, whether good or bad. A company that gets glowing reviews from all references is probably a safe bet. This is not to say that if a business has the occasional unsatisfied customer it is not a good company, but why take the chance?
There is absolutely nothing wrong with asking HVAC technicians for their proof of certification. In fact, this is the first thing you should do when searching around for an experienced HVAC technician to tend to heating and cooling issues. You should also base your decision on how many years of experience he or she has.
A legit and professional HVAC technician will provide you with written and signed details about the services with which he or she is going to provide you and also how much you will be charged for any services rendered. When money matters, obtaining several quotes from a number of different HVAC technicians will help you to quickly narrow down your list of available technicians.
Always make sure that the technician that you hire will write and sign a detailed description of the services that he or she is going to provide for you. The details should include the start and end dates of the project being completed, how much you will be charged, insurance claims that are being filed, and more. In the United States, it is best to partner with an HVAC technician that is willing to provide you with a copy of the “load” calculations; this is especially important if you are having heating and cooling equipment installed within a newly-constructed structure.
There is no exact number of bids that you should obtain from different HVAC technicians, but getting bids is important. You will quickly discover that several technicians can be eliminated from your list of options due to their bids being too high. After you obtain enough bids to allow you to feel comfortable with choosing a technician, make sure that you compare the bids with the services that are to be provided. The lowest bid does not always mean you are getting the best deal. A competent HVAC technician will provide you with a reasonable price bid that combines the products and services that he or she is to provide.
A heating, ventilation, and air conditioning (HVAC) technician installs and repairs commercial and residential heating, cooling, and refrigeration equipment. You can prepare for this job by graduating from high school and then pursuing HVAC education in a certificate, diploma, or degree program. You will usually need training as well, which you can obtain through an internship, apprenticeship, or job. Certification and licensing requirements typically vary by jurisdiction; if either is required, or preferred, you will typically have to demonstrate proof of your training or educational background and pass an exam to earn it.
Education is a good place to start when you want to become an HVAC technician. For example, earning a high school diploma or General Educational Development® (GED®) credential is generally required to work in this field. Earning either of these credentials may make you a more desirable job candidate as well, and prove helpful if you choose to seek formal education. For instance, after graduation, you might choose to pursue a training program via a trade school or a community college.
In addition to education, you will likely need some training to become an HVAC technician. This can take the form of on-the-job training working for a licensed or certified technician, an internship, or an apprenticeship. Some educational programs even offer training as part of the program. You might also find some employers who will hire you for an entry-level position and allow you to learn as you go, but these positions are sometimes a challenge to find.
Whether or not you need a license or certification to become an HVAC technician depends on your jurisdiction. Some require it while others do not. If certification is voluntary in your jurisdiction, you may find that some employers prefer it. Typically, you will have to prove your training and experience and then pass a test to gain certification or licensing.
In order to become a heating ventilation and air conditioning (HVAC) apprentice, one must either attend a reputable career school, work through an HVAC association, or go directly to a current technician and ask about internship or apprentice possibilities. Any of these methods is suitable to become an HVAC apprentice in some areas, but the exact guidelines for becoming a technician after the apprenticeship is over will vary based on the area. The best choice will also depend on exact organization and company guidelines as well as availability of the programs.
One way in which to become an HVAC apprentice is to contact a local company or technician and ask about potential opportunities. Some companies will allow apprenticeships for those with no prior experience or schooling, but others will only take those who have either completed a training program or are in the process of doing so. Each business may have its own rules and guidelines, so it is important to discuss all training, education, and goals with any of them you are considering applying with.
There are also national or international organizations dedicated to heating and air conditioning. They often offer programs which allow students or potential students to become an HVAC apprentice. This is one of the most notable ways of becoming an apprentice since most of these programs are nationally recognized and offer comprehensive training. Some of them also have schooling available followed by an apprenticeship.
Another way to become an HVAC apprentice is by contacting companies through your school. This is usually reserved for students who are in their last semester or two of training; they are able to go out into the field and work as a paid apprentice during the last part of schooling.
Heating, ventilation, and air-conditioning (HVAC) supervisors oversee the installation and maintenance of HVAC systems. They handle tasks ranging from employee management to quality control. If you want to become an HVAC supervisor, you'll have to earn your high school diploma, and many companies also require some college or trade school training.
Extensive work experience in the heating and air conditioning industry can also help you become an HVAC supervisor, as this type of experience helps managers lead crews more effectively. Prospective HVAC supervisors must also possess an understanding of basic construction processes, including scheduling, blueprint reading, and coordination among trades. Finally, managers must be prepared to demonstrate strong leadership skills to prove they are capable of leading employees during HVAC projects.
During this time in the field, employees hoping to become an HVAC supervisor should learn as much as possible about the HVAC trade and the construction industry as a whole. This includes understanding how different trades coordinate with one another on a jobsite, and the order in which different tasks should be completed to maximize performance.
Any prospective supervisors should also take the time to learn skills like blueprint reading, which is essential in the HVAC industry. It is also helpful to have a basic understanding of electrical systems, as these systems interact with those used in HVAC work. All supervisors in the construction field must be aware of safety codes, as well as general industry standards that govern how work should be completed. Potential supervisors should also develop strong computer skills to prepare themselves to handle the responsibilities associated with HVAC management.
Choosing the best heating, ventilation and air conditioning (HVAC) technician training program is a matter of determining what it takes to be successful in the HVAC industry and choosing the program that best fits those needs. When you look for a HVAC technician training program, consider whether you will focus on a certain area of expertise, and look for a program that specializes in that area. Look for a school that has instructors with experience in the field, advanced computer technology and a wide variety of course subjects, and find out which schools have a high graduation rate.
HVAC technician training programs often last from six to 24 months. An HVAC technician training school that offers an apprenticeship program will far outweigh the benefits of a program that does not offer this type of training. An employer often will hire an apprentice after the apprentice becomes a certified HVAC technician. A valuable education comes with learning on-the-job skills and hands-on training.
After you have completed the initial phase of technical training, you might specialize in a certain area of expertise, such as system installation, system maintenance or system repair. Equipment specialization also is an option, and it might include geothermal installation, commercial refrigeration, oil burners or even solar panel installation.
A technical school that offers continuing education classes and specialization in a certain area of HVAC expertise will be invaluable to you. Some technical programs even offer assistance with job placement to assist the graduate to find HVAC work.
When a heating ventilation and air conditioning (HVAC) system is running properly, a home should be kept at a relatively constant temperature. This temperature is generally set by the homeowner on a central thermostat, thereby allowing him or her to keep the house at a comfortable level. Sometimes, however, the system needs a little help in maintaining a consistent temperature throughout the home. HVAC efficiency can be improved by reducing the workload of the system.
One of ways of improving HVAC efficiency is to make sure proper insulation has been installed. Very old homes may have little insulation or the wrong kind altogether. This can result in rooms that do not hold hot or cold air efficiently, resulting in a system that runs longer and harder to make up the difference. Not only does this mean less comfortable room temperature, but higher energy bills as well.
Choosing the right system is another important factor in HVAC efficiency. Some units are more efficient than others. There are some heating and cooling systems that are sophisticated enough to change the temperature automatically while homeowners are away from home or sleeping. This can save hundreds per year on the home's energy bill.
The most important thing to remember in terms of HVAC efficiency, is to keep all doors and windows secured and to make sure the system has proper maintenance. Filters should be changed regularly, and vents should be kept open in rooms that need to be heated. Regular cleaning of the vents and outdoor components can also be beneficial.
Like anything else, your heating and air conditioning systems require proper maintenance. One of the most important types of HVAC maintenance is cleaning. Dust and other particles can accumulate, which may cause your unit to function less than optimally. When your system doesn’t run properly, it can cost you money and provide less comfort.
Parts need to be cleaned and so do filters. Cleaning filters is a routine part of HVAC maintenance and it is imperative that it be done at regular intervals. It is also important to make sure vents and ductwork are clean. Using a vacuum is generally the best option. This helps keeps things running smoothly but also helps keep pollutants and allergens out of the air.
With many companies, you can schedule regular HVAC maintenance visits in advance. Replacing filters or other parts, or making minor repairs is another type of HVAC maintenance. Your heating or cooling unit may not need to be replaced in its entirety, but parts of it might in order to ensure that each unit performs safely and efficiently. The same is true for ductwork. Minor repairs made in time can prevent bigger jobs in the future.
If you are uncomfortable with or unable to handle these issues, call a reputable HVAC service. Regular HVAC maintenance also helps with troubleshooting. A potential problem can possibly be avoided, if it is noticed in time. You may be able to avoid downtime and expense by catching problems early, thus paying a little now to save a lot later. You don’t want to find yourself calling an HVAC technician in the middle of a cold, winter night because your furnace has unexpectedly stopped working.
In the heating, ventilation, and air conditioning (HVAC) industry, equipment servicing is usually preceded by the issuance of HVAC service contracts. The main purpose of this is to define the terms of service as well as the length of service, the cost, and what needs to be done, and each package of contracts is unique to each type of service. These service contracts include full-coverage, full-labor, preventative-maintenance, inspection contracts, and end-use contracts.
The most extensive type of HVAC service contracts is the full-coverage service contract. Labor, parts, materials, preventative maintenance, and emergency service are covered are usually included. Repair and replacement coverage may be included or be available to purchase as part of this contract, which places full responsibility of all the HVAC equipment on the contractor. These are the most expensive form of HVAC service contracts but can be more cost-effective in the long run. Contractors can sometimes terminate them early if they foresee mounting equipment costs.
Unlike a full-coverage contract, a full-labor service contract does not cover the installation of parts, which typically includes items such as chillers, boilers, and air compressors. Instead, its coverage is focused on HVAC repairs, replacement, and maintenance. Large building owners, who can afford such equipment from manufacturers, typically are the only ones that benefit from this agreement.
A preventative-maintenance contract includes scheduled routine operations, such as belt and filter replacements, coil cleaning, lubrication of motors, and painting in order to prevent corrosion. These types of HVAC service contracts are less expensive up front but can be more costly in the long run. An inspection service contract can often be purchased on an annual basis and includes a specified number of inspections. The tasks performed under this contract are typically simpler, and materials costs may or may not be included.
If you want to become a heating, ventilation, and air conditioning (HVAC) service technician, you will need to prepare by attending a technical school or completing an apprenticeship with an accredited program. Your job will most likely include repairs, installation, and sales of HVAC systems, and you can specialize in industrial or residential work. Careers in HVAC services are expected to grow. Due to wear on existing systems and changes in climate control technology, prospects to become an HVAC service technician are very good.
Community colleges or technical schools offer HVAC training programs that usually take around two years to complete. You’ll take classes in computers, electronics, mechanical applications, math, plumbing, and electrical work. Apprenticeships are one way to learn this career but you will need to find an accredited program, which may combine classroom work with paid on-the-job training. These programs require a high school diploma or equivalent and typically last three to five years.
Many locations require you to be licensed. US technicians who are certified to work with refrigerants will test with an approved examiner in handling and disposal of these chemicals. They may qualify in Type I small appliance, Type II high-pressure, and Type III low-pressure refrigerants, depending on their area of specialization. Continued training and recertification will probably be necessary over time because your job will change with new technologies and advancements in climate control systems.
After you become an HVAC service technician, your opportunities for advancement include service sales and supervisory positions. Good technicians may be able to find jobs that pay more, and may open their own business in time. New systems will always be needed, and existing ones will require repairs, so there is lots of job security. Any chance you have to learn about new types of systems and computers will make you more marketable to potential employers in different areas.
In order to become an HVAC design engineer, you need to have earned a bachelor’s degree in HVAC technology, mechanical engineering, or architectural engineering. You may also need to hold some type of specialized professional engineer certification as well. If you plan to become an HVAC design engineer, you should also possess excellent communication and design skills, as well as good time and project management abilities.
Many different colleges and universities offer courses in HVAC (heating, ventilation and air conditioning) engineering. A HVAC-related bachelor’s degree can be obtained technology, design systems, or engineering technology. In order to become an HVAC design engineer, you will need to learn the different types of HVAC systems and respective applications. You must need to know how to make buildings more energy efficient as well as how to create blueprints for projects using computer aided design and drafting systems.
As an HVAC engineering student, you will learn about the different methods used to identify and evaluate heating, ventilation and air conditioning systems in various residential, commercial and industrial buildings. You will likely be instructed in the fundamentals of electricity, refrigeration, and building construction as well. In some colleges, it may be possible to participate in some type of on-the-job internship or apprenticeship program in order to gain practical hands-on work experience before you become an HVAC design engineer.
Once you have become an HVAC design engineer, you may want to consider earning some type of professional engineer certification. Holding a professional certification ensures that your work as an engineer is not only highly competent, but is also in compliance with local and regional regulations as well. Becoming a certified engineer may also help to enhance your professional standing among your peers in the engineering field. In the U.S. professional certification is often obtained through the American Society of Heating, Refrigerating and Air Conditioning Engineers.
Heating, ventilation, and air conditioning (HVAC) systems are used to heat or cool the air in the home while replacing stale air with fresh supplies from outdoors. One of the primary factors to consider when choosing an HVAC system is the size of the system. HVAC sizing refers to the performance capabilities of the system, rather than the size of equipment or air handling units. The size of an HVAC system is rated in British Thermal Units (BTUs), which measure the volume of air the system can produce.
The majority of residential HVAC systems are sized incorrectly, which can produce a number of drawbacks to homeowners. An under-sized system will not heat or cool sufficient quantities of air to keep the home comfortable, while an over-sized system will often cause the home to be too hot or cold. Systems that are too small will not be capable of controlling moisture and humidity within a home, and will not be able to provide effective ventilation. Over-sized systems are often noisy and expensive to operate. They also cost more up front because of the larger heating and cooling units that must be purchased.
HVAC sizing under ACCA Manual J starts with determining air volume needs based on square footage. Volume is then added or subtracted from the original calculation based on insulation, air leakage, and climate. Homes located in very hot areas will naturally require greater cooling loads than those in more moderate regions.
Structures that are tightly insulated and have few air leaks will require smaller systems than buildings that are poorly insulated. Contractors also consider building orientation, shading, appliance loads, and many other individual factors when determining HVAC sizing.
The term HVAC control refers to a system of automated climate control in buildings. HVAC is an acronym for heating, ventilation, and air conditioning, and encompasses the complete internal climate manipulation of any building or space. HVAC control systems typically consist of computerized networks in large buildings and stand alone, single controller systems in homes or smaller venues.
Both constantly monitor and adjust the internal climate of a building according to preset parameters measured against the input of sensors placed throughout the space. These climate control systems often include peripheral functionality such as fire protection, lighting, and security and may also feature diagnostic and remote control capabilities.
HVAC control terminals are generally driven by direct digital control (DDC) software that can be programmed with user-specific data. Depending on the sophistication of the system, users can define a large range of climatic criteria for their environment. These include identifying zones or specific areas within the space, controlling temperatures and air flow, and setting specific times for heating or cooling cycles in those specific areas.
Increasing sophistication in HVAC control technology and demand for one-stop solutions have also seen the inclusion of lighting control, security system monitoring, and fire protection included in these applications. Another recent development is remote access functionality which allows users to initiate HVAC controls via Ethernet connections.
Choosing the best ductwork design can mean the difference between having a heating, ventilating and air-conditioning (HVAC) duct system that works well and one that is inefficient. Many factors go into designing ductwork, including first understanding the requirements of the home or facility. Others — such as duct size, pressure balance, and use of duct equipment such as fittings and terminal boxes — also affect performance. Poorly designed ductwork and improperly sealed ducts can lower the efficiency of any HVAC system by as much as 40 percent.
The right ductwork design can only be determined if the heating and cooling loads of the indoor space are understood. A scale drawing of the building’s air distribution system should be made to indicate where ducts and other equipment will be placed, with the lengths of all ducts clearly shown. Selection and sizing of HVAC equipment for homes is specified in Manual S from the Air Conditioning Contractors of America (ACCA). This guide outlines procedures for using information on blower data, air flow, and room size to determine proper duct size.
The choice of duct layout and duct supplies depends on the structure; for example, laboratories require exhaust systems that have high pressure and need filters to reduce leakage.
A lot of detail goes into ductwork design. It is usually necessary to consult guidelines from the ACCA or seek help from HVAC trade contractors to select the right duct supplies and ensure proper installation. In addition, the location of utilities such as plumbing, communications, and electrical lines, and space requirements for access, must be taken into account when considering ductwork design criteria. When configured properly, an HVAC duct system performs efficiently and quietly.
HVAC pressure is the amount of force generated by a heating or cooling system’s operation throughout a building. HVAC stands for heating venting and air conditioning. In order for a forced air unit to function the way it was intended to, the right amount of pressure must be generated between the air being pulled into the unit and the amount of air being forced out of the unit into the building.
In order to create the correct amount of HVAC pressure, there are a number of factors that must be taken into consideration. First, the size of the building the unit will be providing either heated or cooled air for must be calculated. This is necessary to determine the size of the forced air unit required to maintain a comfortable air temperature for the building.
Once the amount of space the unit will have to heat or cool is determined, the size and type of unit can be decided upon. In order to create enough HVAC pressure within the duct work used to feed temperature controlled air into the building, the unit has to have enough strength to easily push or force the air to the point of the building that is highest in the system. It must do this without becoming overworked.
Once the size of the unit has been determined, the size and design of the ducting that will be run through the building must be determined as well. The size of the ducting is imperative at this point, because ductwork that is too large will not allow the unit to efficiently push controlled air through it. The ductwork that feeds the unit its supply of fresh air must also be of the correct dimensions. If it isn’t, the air flow into the unit can become constricted, which can result in the unit becoming damaged.
A heat load calculator is a tool used by HVAC professionals to determine the necessary size of a furnace and air conditioning unit. This tool was once only available to those professionals, but is now can be found online for free. The calculator takes many factors about a room, from size to window quality, insulation, doors, floors and desired temperature, to calculate the proper BTU output.
A heat load calculator is more of a computer program than a physical calculator, like the kind used in arithmetic. This complex equation that once needed to be performed by hand can now be finished in a few minutes. The calculator is commonly found online as a free program that presents easily filled fields. Precision in inputting these factors is essential to get the proper HVAC system size.
The most physical labor required when operating a heat load calculator comes with measuring the rooms. For each room the HVAC system will reach, the length, width and height must be measured and inputted in feet. Exposed walls, also known as the exterior-facing walls, must also be inputted into the calculator.
The insulation level that needs to be inputted into the heat load calculator takes research, often looking back at remodeling paperwork. The insulation level of the walls and ceilings needs to be entered into the appropriate calculator field. The insulation level, in the United States, is measured between R6 and R20. The higher the number, the thicker the insulation. A heat load calculator will also ask what type of flooring the room has and what level, if any, of insulation is under the floor.
Variable air volume, or VAV, is a type of heating and cooling strategy which is used to adjust or vary the amount of air that is pumped into an enclosed space, based on factors such as ventilation or the energy required to maintain the desired temperature within the space. There are different ways to manage variable air volume, with some systems very simple and straightforward but with limited options, and more sophisticated systems that can be programmed to adjust the volume to meet a wide range of heating and cooling situations.
One of the simplest variable air volume approaches is a system that simply turns off and on when the desired temperature is reached and maintained for a specified period of time. With this approach, the velocity of the air pumped into the space is more or less constant as long as the system is active. A thermostat measures the temperature and signals the air conditioning system to cease operation when the room is within the right temperature range, then sends a second signal to begin delivering air to the space when the temperature moves out of that desired range.
Many of the air conditioning systems used in commercial spaces also make it easy to adjust the variable air volume in terms of speed as well as temperature. Rather than simply shutting down when the desired temperature range is reached, systems of this type will decrease the amount of air flowing into the space when and as needed. This makes it possible to continue pumping fresh air into the space while also allowing the temperature to remain within range for a longer period of time. A system that regulates the variable air volume with this approach is often cost efficient, since the adjustment is automatic and does not require manual intervention.
There are other systems today that offer additional controls and options for managing variable air volume within a given space. With these options, the ventilation system may be configured with multiple points of entry and exit, creating a more efficient flow of air to and from various points within the space. Many of these types of systems today are operated with the use of software technology, making it possible to alter the flow of air from specific vents as well as adjust the temperature of the air flow at different points within the space. This can be especially important in a manufacturing setting, where the temperature near one area of the floor may need to be different from the temperature at the opposite end of the space, owing to machinery or computer equipment that is placed within the area.
In choosing the best duct layout, the two main considerations are the routing and the sizing of the ductwork. A well-designed ductwork system will deliver even temperatures throughout the building, minimize noise, and account for architectural obstacles. Low-cost software is available to assist the designer in establishing an optimal ductwork size while considering the building's architecture and potential obstructions. Round ducts are inherently more efficient and less costly to fabricate, but, in some cases, obstacles or clearances may dictate the use of rectangular ducts.
To design the best duct layout, it is necessary to first determine the air volume each space in the building requires. After that has been established, the number and type of outlets in each space must be calculated in order to deliver the air volume required. Building design constraints must also be accounted for.
Traditionally, HVAC and sheet metal contractors have used a mechanical device called a nomoraph to establish duct sizing. It is easy to use and provides a quick calculation of the optimal dimensions for either round or rectangular ducts. Software, however, gives the designer more real-world methods of calculating optimal duct sizing and routing, and can produce an estimate of material and labor costs. When airflow problems arise with an HVAC system, some software can analyze and recommend modifications to the existing duct layout by simulating the current system.
More advanced duct layout software is capable of importing data from Computer-Aided Design (CAD) drawings, thus minimizing the data that needs to be entered into the duct sizing and layout software. Most publishers of the software make the programs compatible with autoCAD-based design programs. It should be noted that, although CAD programs can assist with the design of the overall HVAC system, they are no substitute for experience and the judgment of an HVAC designer or engineer.
There are four stages to every HVAC installation project: evaluation and quotation of work, tear down, installation of equipment, and final inspection. A heating, ventilation, and air conditioning (HVAC) installation is a major project that requires the use of expert staff, contractors, and inspectors. The four stages are the same for both residential and commercial HVAC installation projects.
HVAC is typically considered to be the lungs of any building. This system is responsible for the heating, cooling and circulation of air within the structure. A well-designed system is energy and cost efficient, operates seamlessly in the background, and provides all areas of the building with a steady stream of clean, temperature-controlled air. There is a wide range of HVAC systems installed in buildings, based on their age and the unique features of the space. However, all new HVAC installations are forced air systems.
Once the installation is finished, the mechanics are responsible for testing the system to make sure it works correctly. Upon completion of their testing, a city or municipal home inspector should come and complete an independent inspection.
The purpose of this inspection is to ensure that your HVAC installation project complies with all the city building codes and health and safety guidelines.
A heating, ventilation and air conditioning (HVAC) system is used to heat and cool a house. Many of these systems also draw fresh air in to ventilate the home, while exhausting stale air. Depending on the application, HVAC systems can be extremely complex, and must include a wide variety of components in order to function properly. HVAC design is typically performed by skilled mechanical engineers or HVAC contractors.
During the HVAC design process, engineers must balance the comfort of building occupants with the need for energy efficiency and safe indoor air quality. To accomplish this, HVAC engineering professionals look at factors such as the size of the building, the local climate, the amount of insulation in the building, and how much heat is escaping the home through uncontrolled means. By the end of the HVAC design process, the engineer will know what kind of heating and cooling equipment to use and how it should be installed for maximum effect.
Throughout much of North America, the most widely used HVAC design standards are those developed by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE). ASHRAE Manual J provides standards for sizing HVAC equipment, while a number of additional ASHRAE publications are used to guide engineers through the design process.
The Air Conditioning Contractors of America (ACCA) is another organization that has developed its own HVAC design standards. ACCA standards are most commonly used by designers in the residential market, though the organization also produces commercial guidelines. In the UK, the Chartered Institution of Building Services Engineers (CIBSE) has developed its own line of standards similar to those created by ASHRAE and ACCA.
Many skilled individuals are involved in the design, sale, installation, and repair of heating, ventilation, and air conditioning (HVAC) units. HVAC workers are essential in providing comfortable, temperature-controlled atmospheres in private residencies as well as offices, schools, hospitals, warehouses, and other large structures where people live and work. People who are interested in HVAC employment might pursue careers as engineers, fabricators, technicians, or salespeople. Depending on the nature of HVAC employment, individuals are usually required to pursue some form of higher education and complete formal training programs.
Research and development departments of HVAC manufacturing plants hire skilled engineers to create, test, and build new units. Engineers use their advanced knowledge of math and physics to design systems that are efficient, cost effective, environmentally friendly, and simple to use and maintain. They commonly employ computer-aided drafting software and various other programs to help them design blueprints and perform hypothetical tests on units.
Many skilled journeymen find HVAC employment as technicians, who are responsible for installing, maintaining, and repairing systems. Professionals follow blueprints and instructions to ensure that new systems are installed properly and safely.
They usually possess detailed knowledge on how to troubleshoot faulty motors, gauges, and pressurized pumps. HVAC technicians are usually required to complete vocational training and lengthy apprenticeships to master the difficult trade. In addition, many states and countries require new technicians to pass extensive licensing examinations before working independently.
An HVAC project engineer is responsible for designing the heating and cooling system that will best meet a client's needs. These professionals must consider the client's output and space needs, as well as any budgetary constraints. Qualifications include formal training in HVAC technology, knowledge of various HVAC options and advances, and the ability to read — and possibly, to draw — blueprints and schematics. Some HVAC companies require candidates to be certified and/or to possess a degree in mechanical engineering. HVAC project engineers most often work for large HVAC manufacturers or distributors, and are part of the team that develops bids and proposals for potential clients.
Before making any recommendations, an HVAC project engineer must perform a site evaluation. This can take anywhere from several hours to several weeks, depending on the size and scope of the project. The engineer must evaluate the existing conditions; determine which parts, if any, of the old system can remain in place; understand which spaces must be heated and cooled; and consider any local codes that will affect the project.
The HVAC project engineer must then provide an estimate for the work. This may include pricing based on brand and construction material recommendations. Many companies require such estimates to be broken down by parts and labor. The estimate should include clear details regarding which services are provided and which are excluded.
The responsibility for systems installation is assigned differently by different companies. Upon approval, the engineer may be responsible for managing the installation of the new system. If so, she will be responsible for interacting with the client to ensure that all tasks are completed, managing the labor crews, ordering equipment, and tracking change orders. Alternatively, she may turn the files over to a project manager and move on to the next project.
HVAC is an abbreviation for "heating, ventilation and air conditioning." An HVAC supervisor is a senior technician who manages a team of technicians who work on heating and cooling systems. In most cases, this is a working manager position. This means that the supervisor performs installation and repair duties in addition to management and administrative duties.
An HVAC supervisor might be involved in many types of jobs. He might work at a residential, commercial or industrial site with a team of installers or repair technicians. His team might consist of a single additional individual or several people of varying skill levels, depending on the size and nature of the job. He might also travel between several jobs, supervising the work of several crews at different sites.
Managerial functions can include hiring and firing employees and conducting performance reviews. Often, an HVAC supervisor is responsible for training new employees as well. He might also provide continuing education training by attending classes on new products and technologies, then returning with the knowledge to train the rest of the staff. In some cases, he may be the only one of a crew with certain certifications, so there may be specific jobs that only he can do.
Few individuals become supervisors immediately upon beginning their careers. HVAC supervisors usually have several years of experience and have proven themselves capable of doing quality work and of leading a team effectively. These professionals often have college educations and a history of attending industry training classes. The supervisor pay rate is generally higher than that of a technician, partly because of this advanced knowledge and experience, but also because of the increased responsibility that comes with the role.
