Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Cottonwood & Prescott, you may be thinking 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 withstand severe weather, including intense temperatures and torrential precipitation.

Sometimes covers create more issues, because they can trap water. Additional wetness inside your unit can cause internal parts to rust or become moldy.

While putting on an air conditioner cover is an individual choice, there are two periods that are ideal for using 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 lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more electricity to cool your home.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Connolly Electric & Mechanical heating and cooling experts can help. We’ll clean and lubricate your equipment, and inspect important pieces. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Total AC covers can trap water inside your system, potentially eating away at metal pieces. It could also make your system a welcoming area for vermin, which could sever wires.
