An air conditioning system has four essential parts:
Evaporator
Compressor
Condenser
Blower
When the thermostat calls for cooling, the system to go into operation. Air is passed over the evaporator coils where it is cooled using refrigerant, and the cooled air is moved through your home via duct work. The outdoor unit, also known as the condenser, houses the compressor and fan. The job of the outdoor unit is to disperse the heat removed from your indoor air, as well as act as a pump for the refrigerant used to cool the air indoors.
