Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Circleville, you may be questioning 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 engineered to withstand inclement weather, including intense temperatures and heavy precipitation.

Sometimes covers create more issues, because they can trap moisture. Additional wetness inside your equipment can cause internal parts to rust or turn moldy.

While installing an air conditioner cover is your own choice, there are two periods that are good to use 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 pile up and block your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more energy to cool your home.

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Stephen Hurst Pack Heating and Cooling, Inc heating and cooling technicians can help. We’ll clean and lubricate your system, and take a close look at critical pieces. This often allows us to pinpoint issues before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a few suggestions on selecting the best cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your unit, potentially corroding metal pieces. It could also make your AC a cozy area for rodents, which could eat through wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is approaching. Snow and ice that build up inside your AC can melt and refreeze, breaking condenser coils and decreasing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your air conditioner if a bad storm is imminent in Circleville. Hail can seriously damage your system’s coils, altering efficiency.
