Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Rockford, you may be thinking when you should cover your outdoor air conditioner. Of if you have to cover it at all.

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

Sometimes covers create more issues, because they can trap moisture. Too much wetness inside your system can cause internal pieces to rust or turn moldy.

While using an air conditioner cover is your own choice, there are two periods that are great for using a cover for a long period of time—fall and summer.  

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

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a few suggestions on selecting the best cover. 

Avoid Full Covers

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

Complete AC covers can trap condensation inside your system, potentially corroding metal components. It could also make your system a welcoming area for animals, which could sever wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is on the way. Snow and ice that build up inside your system can melt and refreeze, damaging condenser coils and reducing efficiency.
