With cold weather approaching in Phoenix, 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 created to resist inclement weather, including intense temperatures and torrential precipitation.

Sometimes covers do more harm than good because they can trap water. Extra wetness inside your unit can cause internal pieces to rust or become moldy.

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

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can accumulate and lower your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more power to cool your home.

How to Find Your Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple suggestions on picking the right cover.

Avoid Full Covers

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

Total AC covers can trap water inside your unit, potentially rusting metal pieces. It could also make your air conditioner an inviting place for vermin, which could sever wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a blizzard is on the way. Snow and ice that build up inside your air conditioner can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your air conditioner if a bad storm is coming in Phoenix. Hail can critically damage your system’s exterior, altering efficiency.
