Lennox Split System Heat Pumps in Eugene City – What is an HVAC Unit?
An HVAC unit is a term used for a centralized heating, ventilation and air conditioning system. An HVAC unit allows for the convenient regulation of the interior temperature and climate of a building. Before the advent of the modern HVAC system, effective interior cooling and heating were often limited to a specific room or portion of a building with localized heating or cooling.

An HVAC unit provides interior cooling by drawing warm interior air into the system through a series of air return ducts. The air is then moved over a series of refrigerated coils. As the air moves over the coils, the heat in the air is transferred to the refrigerant in the coils. A fan or blower sends the cooled air back to the interior of the building through a series of ducts.
As air is drawn into the HVAC unit, it is also directed through a series of filters. The interior air of a building is a mixture of a variety of things such as human skin particles, insect droppings, pet dander, and pollen. The filtration system protects the unit from these and other airborne pollutants that could cause damage if allowed to enter the inner workings of the unit.

Filters not only protect the HVAC system, but some types of filters are designed to improve the air quality of a building. A HEPA (High Efficiency Particulate Arrestance) filter captures a minimum of 99.7% of all airborne particles and removes almost all allergens from the air. As pollutants are trapped in the filter, they are prevented from re-entering the building when the air is directed back into it.
