With cold weather on the horizon in Cedar Rapids, 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 sturdy piece of equipment. It’s designed to resist severe} weather, including extreme temperatures and torrential precipitation.

Sometimes covers do more harm than good because they can trap condensation. Additional wetness inside your equipment can cause internal pieces to rust or become moldy.

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

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

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

To keep air flowing, a protective air conditioner cover should only surround the top of your unit and a couple of inches on the side.

Total AC covers can trap water inside your equipment, potentially rusting metal parts. It could also make your air conditioner a welcoming place for rodents, which could chew wires.
