Do I Need to Cover My Air Conditioner?

With cold weather approaching in McMurray, you may be wondering when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a sturdy piece of equipment. It’s engineered to resist severe weather, including intense temperatures and torrential precipitation.

Sometimes covers cause more problems, because they can trap water. Additional wetness inside your system can cause internal components to rust or become moldy.

While installing an air conditioner cover is an individual 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 waste during those seasons—grass clippings, twigs and leaves—can pile up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works more and may use more power to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Kowalski Heating, Cooling & Plumbing heating and cooling technicians can help. We’ll clean and lubricate your unit, and inspect important components. This often allows us to identify 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 a few ideas on selecting the right cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your unit, potentially corroding metal components. It could also make your system an inviting place 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 accumulate inside your AC can melt and refreeze, damaging condenser coils and reducing efficiency.
