Room Air Conditioner Repairs
A room air conditioner that doesn't cool may need to be recharged with refrigerant¡ªa task you should leave to a professional¡ªbut often just needs to be cleaned. To clean the coils and filter:
* Unplug the unit. You may need to remove it from the window (be careful¡ªit's heavy!)
* Remove the air inlet grill and remove the filter;
* Wash the filter or replace it with a disposable one;
* Vacuum the coils' fins with a soft brush attachment;
* Spray water back through the fins from the fan side (cover the wiring and motor with plastic);
* Check to be sure that the drains are clean;
* Lubricate the motor¡ªcheck the owner's manual for instructions; and
* Reassemble and reinstall the unit.
