Do I Need to Cover My Air Conditioner?

With cold weather coming in Phoenix, 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 designed to withstand bad weather, including excessive temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap water. Additional wetness inside your equipment can cause internal components to rust or get moldy.

While installing an air conditioner cover is your own choice, there are two times of year that are good to use a cover for an extended period of time—fall and summer.  

That’s because yard rubbish during those seasons—grass clippings, twigs and leaves—can pile up and block your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more energy to cool your house.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Dial One Mears Air Conditioning & Heating Inc heating and cooling technicians can help. We’ll clean and lubricate your system, and take a close look at important pieces. This often allows us to spot issues before they begin.

How to Choose an Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a couple ideas on selecting the ideal cover. 

Avoid Full Covers

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

Full AC covers can trap condensation inside your system, potentially rusting metal parts. It could also make your AC 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 approaching. Snow and ice that accumulate inside your AC 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 strong storm is imminent in Phoenix. Hail can seriously damage your system’s coils, affecting efficiency.
