Do I Need to Cover My Air Conditioner?

With cold weather approaching in Baltimore, 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 strong piece of equipment. It’s designed to resist severe weather, including extreme temperatures and heavy precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Additional wetness inside your system can cause internal parts to rust or get moldy.

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

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

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Quality Refrigeration Services heating and cooling experts can help. We’ll clean and lubricate your equipment, and take a close look at critical parts. 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 couple suggestions on choosing the best cover. 

Avoid Full Covers

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

Complete AC covers can trap moisture inside your unit, potentially corroding metal parts. It could also make your system a cozy home for rodents, which could sever wires.

Plastic or vinyl covers block air, which could cause water to build up inside your unit. The best type of fabric is one that lets in air, like canvas or mesh.

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 build up inside your AC can melt and refreeze, harming condenser coils and decreasing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your AC if a severe storm is approaching in Baltimore. Hail can seriously damage your system’s fins, impacting efficiency.
