Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Chelan and Wenatchee, you may be thinking 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 created to withstand inclement weather, including extreme temperatures and relentless precipitation.

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

While installing an air conditioner cover is your own choice, there are two seasons that are ideal 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 accumulate and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more electricity to cool your home.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Lakeside Heating & Air heating and cooling professionals can help. We’ll clean and lubricate your system, and take a close look at important pieces. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap water inside your unit, potentially eating away at metal components. It could also make your AC an inviting area for animals, which could chew wires.
