With cold weather on the horizon in Rapid City, 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 designed to resist severe weather, including excessive temperatures and relentless precipitation.

Sometimes covers do more harm than good because they can trap water. Additional wetness inside your unit can cause internal parts to rust or get moldy.

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

That’s because yard debris 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 house.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple tips on choosing the best cover.

Avoid Full Covers

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

Total AC covers can trap moisture inside your equipment, potentially corroding metal components. It could also make your system a welcoming place for rodents, which could sever wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is coming. Snow and ice that build up inside your air conditioner can melt and refreeze, damaging condenser coils and reducing efficiency.
