Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon 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 created to withstand bad weather, including intense temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap moisture. Extra wetness inside your system can cause internal pieces to rust or turn moldy.

While using an air conditioner cover is an individual 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 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 electricity to cool your home.

Seeking other ways to make your air conditioner run efficiently? Annual AC maintenance from Dial One Mears Air Conditioning & Heating Inc heating and cooling experts can help. We’ll clean and lubricate your system, and inspect important pieces. This often allows us to spot problems before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are several suggestions on picking the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap condensation inside your unit, potentially eating away at metal components. It could also make your AC an inviting area 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 heavy snow is on the way. Snow and ice that collect inside your system can melt and refreeze, breaking condenser coils and decreasing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your system if a strong storm is imminent in Phoenix. Hail can severely damage your system’s coils, altering efficiency.
