Window AC maintenance suggestions speak to how to maintain a window AC unit and window AC maintenance procedures are for single room air conditioners. Maintenance procedures will be outlined in the manufacturer's instructions that are provided with the unit.
To properly maintain ac equipment it is suggested that the various parts of the air conditioner be understood.
The major parts of an air conditioner manage refrigerant and move air in two directions: indoors and outside:
The cold side of an air conditioner contains the evaporator and a fan that blows air over the chilled coils and into the room. The hot side contains the compressor, condenser and another fan to vent hot air coming off the compressed refrigerant to the outdoors.
In between the two sets of coils, there's an expansion valve. It regulates the amount of compressed liquid refrigerant moving into the evaporator. Once in the evaporator, the refrigerant experiences a pressure drop, expands and changes back into a gas.
The compressor is actually a large electric pump that pressurizes the refrigerant gas as part of the process of turning it back into a liquid. There are some additional sensors, timers and valves, but the evaporator, compressor, condenser and expansion valve are the main components of an air conditioner.
Although this is a conventional setup for a window air conditioner, there are a couple of variations you should know about. Window air conditioners have all these components mounted into a relatively small metal box that installs into a window opening.
The hot air vents from the back of the unit, while the condenser coils and a fan cool and re-circulate indoor air. Bigger air conditioners work a little differently.
