Do I Need to Cover My Air Conditioner?

With cold weather approaching in Racine, you may be wondering 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 resist severe weather, including excessive temperatures and heavy precipitation.

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

While putting on an air conditioner cover is your own choice, there are two times of year that are ideal for using a cover for an extended period of time—fall and summer.  

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

Seeking other ways to make your air conditioner run efficiently? Annual AC maintenance from Keystone Heating & Air Conditioning Co., Inc heating and cooling experts can help. We’ll clean and lubricate your equipment, and inspect critical components. This often allows us to pinpoint problems before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple ideas on picking the right cover. 

Avoid Full Covers

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

Total AC covers can trap moisture inside your unit, potentially eating away at metal components. It could also make your AC a cozy 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 heavy snow is approaching. Snow and ice that accumulate inside your system can melt and refreeze, harming condenser coils and lowering efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your AC if a severe storm is coming in Racine. Hail can severely damage your system’s fins, altering efficiency.
