Do I Need to Cover My Air Conditioner?

With cold weather on the horizon in Rock Hill, 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 resist severe 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 components to rust or turn moldy.

While putting on an air conditioner cover is a personal choice, there are two seasons that are good to use a cover for a lengthy period of time—fall and summer.  

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can accumulate and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works more and may use more electricity to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from US Air Heating and Cooling heating and cooling professionals can help. We’ll clean and lubricate your system, and take a close look at important components. This often allows us to pinpoint issues before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are several tips on selecting the best cover. 

Avoid Full Covers

To keep air moving, a protective air conditioner cover should only encompass the top of your equipment and several inches on the side.

Full AC covers can trap moisture inside your equipment, potentially eating away at metal parts. It could also make your AC a cozy home for vermin, which could chew 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 collect inside your system can melt and refreeze, harming condenser coils and decreasing efficiency.
