It cleans the air that is circulated through the air conditioner system. The air filter should be replaced quarterly.
- Air Blower and Handler: The air handler and blower operate jointly to take in air to the evaporator from inside of your home. This air intake is circulated all over the entire house.
- Evaporator: The evaporator of an air conditioner receives the liquid refrigerant and converts the refrigerant into gas. This gas works to dehumidify and cool the indoor air. The evaporator is usually situated in an area of the air conditioning unit that is cold.
- Condenser: The condenser is located in the area of the air conditioner that is hot. It complements the evaporator. The condenser condenses the gaseous and vaporized refrigerant and ejects heat to the outside of your home. This process converts the vaporized refrigerant back into a liquid refrigerant.
- Compressor: The compressor is responsible for converting the gaseous refrigerant under high pressure back into the liquid refrigerant. The compressor works together with the condenser. It is situated in the hot area of your or conditioning unit.
- Expansion Valve: The expansion valve is situated between the evaporator and the condenser. It regulates the quantity of liquid refrigerant that follows the evaporator.
