Your home comfort system is a complex machine and one of the most expensive investments you’ll make in your home. Thus air conditioning repair can be an costly proposition. Only certified, insured air conditioner professionals should be allowed to service, maintain, repair or install your heater, air conditioner, or ventilation system.
A correctly installed and maintained system can last for many years and save you a lot of money in the process. While it is never recommended that inexperienced, untrained homeowners attempt do-it-yourself air conditioning repair, one should learn as much as possible about their home comfort system. Below is a brief explanation of its parts and inner workings.
Using a compressor, the condenser pumps refrigerant to the air handler or evaporator coil.
Earning its name, the blower motor pulls hot air from inside the home and blows it across the evaporate coil.
The cooled refrigerant from the compressor acts as a sponge to absorb the warm air from the blower motor. Cooled air is then pushed through the air ducts and comes out through the supply.
Warmed air from the air handler/evaporator coil returns to the condenser and expels heat in the refrigerant through the outdoor coils and fan.
