Air Conditioner Maintenance Tips

Condensing coils

The condensing coils on an air conditioner will get very dirty over time. However, the dirt tends to accumulate on the inside of the coils, out of sight. It will be necessary to remove the entire cover of the air conditioner to gain access to the coils. They can be cleaned by blowing compressed air through them or by using a soft bristle brush to wipe the dirt off. It is important to also clean any dirt or lint build-up in the bottom of the air conditioner so the condensate water will be picked up by the condensing fan slinger properly.Pictures


Air conditioners are outfitted with a filter in the front grill area to filter the air that passes through them. If your unit has a filter you should replace/clean it once a month during the cooling season.

Frost on coils

If the outdoor temperature becomes too cool, approximately 60 degrees Fahrenheit or lower, check the coils on the front of the air conditioner to be sure they are not icing up. If ice has accumulated, turn the air conditioner off until the temperature rises. This usually is caused from running the air conditioner overnight.
