With cold weather approaching in Des Moines, you may be questioning 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 engineered to resist severe} weather, including excessive temperatures and relentless precipitation.
Sometimes covers create more issues because they can trap condensation. Additional wetness inside your system can cause internal components to rust or get moldy.
While putting on an air conditioner cover is your own choice, there are two periods that are good to use a cover for a lengthy period of time—fall and summer.
That’s because yard debris during those seasons—grass clippings, twigs and leaves—can pile up and block your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more power to cool your house.

How to Choose an Air Conditioner Cover
If you determine you want to cover your air conditioner, here are a few ideas on choosing the ideal cover.
Avoid Full Covers
To keep air circulating, a protective air conditioner cover should only enclose the top of your system and a few inches on the side.
Total AC covers can trap moisture inside your system, potentially corroding metal pieces. It could also make your system a welcoming area for animals, which could eat through wires.
