Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Wisconsin Rapids, you may be wondering when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a strong piece of equipment. It’s created to withstand inclement weather, including extreme temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap water. Too much wetness inside your unit can cause internal pieces to rust or turn moldy.

While installing an air conditioner cover is your own choice, there are two times of year that are good to use a cover for a lengthy period of time—fall and summer.  

That’s because yard rubbish during those seasons—grass clippings, twigs and leaves—can build up and lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more electricity to cool your home.

How to Choose an Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are several suggestions on choosing the right cover. 

Avoid Full Covers

To keep air moving, a protective air conditioner cover should only encompass the top of your system and several inches on the side.

Total AC covers can trap moisture inside your unit, potentially corroding metal components. It could also make your AC a welcoming home for vermin, which could eat through wires.
