With cold weather approaching in Des Moines, you may be questioning 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 engineered to take on severe weather, including intense temperatures and torrential precipitation.
Sometimes covers do more harm than good, because they can trap condensation. Extra wetness inside your system can cause internal parts to rust or turn moldy.
While using an air conditioner cover is a personal choice, there are two periods that are good to use 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 accumulate and block your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more electricity to cool your home.

How to Choose an Air Conditioner Cover
