Do I Need to Cover My Air Conditioner?

With cold weather on the horizon 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 sturdy piece of equipment. It’s engineered to resist bad weather, including intense temperatures and torrential precipitation.

Sometimes covers create more issues, because they can trap condensation. Too much wetness inside your equipment can cause internal pieces to rust or turn moldy.

While putting on an air conditioner cover is an individual 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 debris during those seasons—grass clippings, twigs and leaves—can accumulate and lower your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more power to cool your residence.

Looking for other ways to make your air conditioner run efficiently? Routine AC maintenance from Northern Comfort Inc heating and cooling technicians can help. We’ll clean and lubricate your equipment, and examine critical pieces. This often allows us to identify trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are several ideas on picking the best cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your equipment, potentially corroding metal pieces. It could also make your system a welcoming area for vermin, which could sever wires.
