What Happens When an Air Conditioner Sits All Winter?

Parts

• Air conditioning systems are typically comprised of two main parts: a compressor and a blower. While the compressor doesn't function when the air conditioner is turned off, the blower works year-round, circulating warm air throughout your home in the winter months and cool air in the summer. Therefore, the blower unit tends to break down more often.

Dirt

• When an air conditioner rests idle during the winter months, dirt, dust and debris can gather inside. Therefore, it's a good idea to open up your air conditioner and clean it before turning it on in the summertime.

Air Filter

• Replace the air filter on your air conditioner for the new season. This will ensure the air conditioner continues to function throughout those long, hot days of summer.
