Understanding How Your AC Functions

Published on: May 16, 2012

You use your air conditioner system without much thought, but you should have a basic working knowledge of how it works and what is inside. Having basic knowledge about your central air conditioner system will help when you have to call for an air conditioning repair. Find a qualified and professional HVAC contractor for air conditioning repairs, service, installation, or maintenance on your system.

Compressors, Evaporators, and Condensers

The three important components of your air conditioner are the condenser and evaporator coils and compressor. Evaporator and condenser coils are serpentine tubes constructed of copper and surrounded by aluminum fins. The Interior evaporator coil cools the space with refrigerant and the exterior condenser coil collects and releases the heated air from inside the building. The compressor is the pump that moves the refrigerant through the evaporator and condenser coils.

If your air conditioner is a split system, it has an outside metal cabinet containing the condenser and the compressor, and the indoor cabinet contains the evaporator. When you call a HVAC contractor for air conditioning repair, it is helpful to know the type of system that cools your home or business, but it is not necessary.

Air Conditioner Refrigerant

Chlorofluorocarbons or CFCs are damaging to the Earth’s ozone layer and originally used as the only air conditioner refrigerant. However, halogenated chlorofluorocarbons or HCFCs replaced CFCs as a better alternative. Today, hydrofluorocarbons or HFCs have replaced HCFCs as an ozone and environmentally friendly option. By 2020, HCFCs will be unavailable for use. If the air conditioning repair on your system requires replacing refrigerant, confirm that the refrigerant used does not contain CFCs.

If you are interested in reducing the cost of air conditioning repairs for your system, make sure to have a HVAC contractor perform yearly tune ups and scheduled maintenance.
