Proper Cleaning of Air Conditioner

Warm air from the air conditioning unit does not always mean of low on refrigerant.  Many times, window and through-the-wall air conditioning units can’t blow cold air because the evaporator and condenser coils or cooling fins are clogged.

Below can be your tips on cleaning the unit:

First remove the plastic filter holder/trim panel, as it usually snaps off. Then remove it from the window or slide it out of the wall.  Caution:  it’s heavy so ask for assistance.

Remove the mounting frame and the case if working on a window unit. The case screws are basically located along the bottom edge. Note the location of any odd-length screws as they have to go back in the same spots after reassembly.

After which, straighten the bent cooling fins with a fin comb.

Buy two cans of air conditioner coil cleaner. Vacuum all visible buildup from both coils, and spray both coils with the cleaner. Clean the fan blades with household cleaner and a rag while the foam works. Pop them and squeeze in a few drops of electric motor oil if the fan motor has plastic- or rubber-capped oiling ports.

Wash or replace the air filter and reinstall the unit. It just might blow a lot cooler. Otherwise other problems is at stake !
