Do I Need to Cover My Air Conditioner?

With cold weather coming in Mankato area, you may be wondering when you should cover your outdoor air conditioner. Of if you have to cover it at all.

Your AC unit is a strong piece of equipment. It’s engineered to take on bad weather, including extreme temperatures and torrential precipitation.

Sometimes covers create more issues, because they can trap water. Additional wetness inside your unit can cause internal pieces to rust or turn moldy.

While installing an air conditioner cover is a personal choice, there are two seasons that are good to use 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 build up and lower 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 Northern Comfort Inc heating and cooling technicians can help. We’ll clean and lubricate your equipment, and examine critical components. 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 selecting the ideal 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.

Total AC covers can trap water inside your equipment, potentially corroding metal components. It could also make your system a cozy place for rodents, which could eat through wires.
