Do I Need to Cover My Air Conditioner?

With cold weather coming in Opelika, 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 engineered to withstand severe weather, including intense temperatures and relentless precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Too much wetness inside your equipment can cause internal parts to rust or turn moldy.

While installing an air conditioner cover is a personal choice, there are two seasons that are great for using 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 pile up and block your system’s airflow. Decreased airflow means your air conditioning unit works more and may use more electricity to cool your house.

Seeking other ways to make your air conditioner run efficiently? Routine AC maintenance from Farnell Mechanical, Inc. heating and cooling technicians can help. We’ll clean and lubricate your system, and take a close look at essential components. This often allows us to pinpoint trouble 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 several tips on picking the best cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your unit, potentially corroding metal components. It could also make your AC a welcoming area for vermin, 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, damaging 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 approaching in Opelika. Hail can critically damage your system’s coils, affecting efficiency.
