With cold weather approaching in Phoenix, you may be wondering when you should cover your outdoor air conditioner. Of if you should even cover it at all.

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

Sometimes covers cause more problems because they can trap water. Too much wetness inside your system can cause internal pieces to rust or become moldy.

While putting on an air conditioner cover is your own choice, there are two times of year 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 accumulate and block your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more power to cool your home.

Choosing the Right Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a few tips on selecting the best cover.

Avoid Full Covers

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

Complete AC covers can trap condensation inside your equipment, potentially rusting metal pieces. It could also make your system a cozy home 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 snowstorm is on the way. Snow and ice that accumulate inside your system can melt and refreeze, breaking condenser coils and reducing efficiency.
