Window AC Repair Tips
Window AC repair is not a difficult thing, because these units are compact and don’t have lots of complicated parts. There are certain problems that should be addressed by a trained repair technician, but most people can handle basic window AC repair problems themselves.
Typical window AC repair problems and solutions
- Dirty filters. Air circulates through the filters in your window air conditioner, and these filters get dirty from time to time. Dirty filters will cut down on your unit’s efficiency, which will eventually mean higher electric bills for you. If you want your window air conditioning unit to run well, it’s important to change or clean the filter once a month in the hot weather. There are other parts that need regular care and cleaning for the unit to run effectively. While you have the filter out, check the fins (which are located directly behind the filter). These can become clogged with dust and dirt, and that can impair the air conditioner’s performance to the point where it will freeze up. To clean out the fins, use a medium density brush and an up and down stroke. If you find that the fins are covered in ice, defrost the unit by turning it onto the “fan only” setting. The condenser coils should be cleaned at least once a year. It’s an easy job: simply unplug the air conditioner long enough for the condenser coils to dry, then vacuum the coils thoroughly. You can also clean the coils with a soft toothbrush, to get into the crevices.
- Musty smells. This is a common problem in older window AC units. A musty smell is usually caused by dust, dirt, and moisture building up and causing mold and mildew to form in the drip tray. To solve this problem, remove the drip tray from underneath the unit, and wash it in warm soapy water. You should do this at least once a year.
- Leaking. People sometimes panic if they discover water leaking from their window air conditioner. Usually the problem is because the unit is tilted in, toward the room, rather than out. If your window air conditioner is installed correctly it will drain out of the back of the unit.
- The fan isn’t blowing. If there is no air blowing through the unit, it’s probably because the fan motor is not running correctly. While the unit is unplugged, turn the fan blades by hand. If the blades don’t turn easily, lubricate the fan motor. If this does not correct the problem, the fan motor may need to be replaced.
Window AC repair is a simple matter if it involves these problems. For anything more complicated, you should call in an AC technician, someone who is trained to handle more serious issues.
