Assuming that the equipment or system is operating normally, the following operations are performed.
Cleaning equipment and parts. The condenser and evaporator must be carefully cleaned to ensure good heat transfer and avoid contamination and overheating equipment. Lubrication mechanisms requiring it: bearings, bearings, bushings.
Reviewing and changing filters in package units, air handlers, fan & coils, minisplits. Filters dirty or damaged impede airflow and reduce the team's efficiency. Filter drier. Normally not given importance to the dryer on air conditioners; often obstructed by dirt inside the system and is very easy to revise.
Some time will be needed major repairs, engine changes, compressor and fan blades. These changes will stop the operation of the equipment or system. It is necessary to provide parts or parts that will be required for the unemployed is in the shortest possible time. You can not have in the maintenance shop all parties, but the most critical or frequent: blades, filters, coolant, bearings.
Some parts are not repairable by the maintenance staff, for example, semi-hermetic compressors and motors. They must resort to a specialized workshop for repairing them; depending on location, will be necessary to have a compressor, a motor and valves in perfect condition to make a change.
From a careful analysis of the logs of equipment may be necessary to predict when a component replacement schedule and so to get the parts and do it at the right time. To incipient failure, usually, it is easy to determine. Is the point of warning that the computer will fail in a remarkably short time. Examples: metal-metal noise in auto brake pads, bands chirp generator, water pump and excessive noise in aims.
The proper functioning of air conditioning systems not only addresses issues of comfort, health and welfare of people who work in offices, hotels, restaurants or hospitals, or those living homes heated. Specialized research units, for example, require exceptionally precise design and optimal facilities. Here there can be no mistake. The minimum margin could cause local infections, including pandemic and killed.
Biosecurity is a matter of life or death. Working in biocontainment work concerns not only excellent designs and engineering maintenance services, involves an internship as delicate as preventing the spread in the environment of highly infectious agents, which must remain in total secrecy.
