Do I Need to Cover My Air Conditioner?

With cold weather approaching in Menomonie and western Wisconsin, 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 take on bad weather, including extreme temperatures and heavy precipitation.

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

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

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can build up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more power to cool your residence.

Seeking other ways to make your air conditioner run efficiently? Annual AC maintenance from Halverson Brothers Inc heating and cooling technicians can help. We’ll clean and lubricate your system, and take a close look at important pieces. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few ideas on choosing the right cover. 

Avoid Full Covers

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

Complete AC covers can trap moisture inside your unit, potentially eating away at metal pieces. It could also make your system a cozy home for animals, which could sever 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, breaking condenser coils and reducing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your air conditioner if a strong storm is approaching in Menomonie and western Wisconsin. Hail can severely damage your system’s coils, impacting efficiency.
