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

Your AC unit is a sturdy piece of equipment. It’s designed to resist inclement} weather, including excessive temperatures and heavy precipitation.

Sometimes covers cause more problems because they can trap moisture. Too much wetness inside your unit can cause internal parts to rust or become moldy.

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

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can pile up and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more energy to cool your residence.

How to Choose an Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a couple suggestions on picking the best cover.

Avoid Full Covers

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

Total AC covers can trap moisture inside your equipment, potentially eating away at metal parts. It could also make your AC an inviting place for animals, which could eat through wires.
