Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Beckley and Mount Hope, you may be thinking 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 created to take on severe weather, including excessive temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap condensation. Extra wetness inside your unit can cause internal components to rust or turn moldy.

While installing an air conditioner cover is your own choice, there are two seasons that are great for using 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 pile up and lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more energy to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Appalachian Heating heating and cooling experts can help. We’ll clean and lubricate your unit, and examine important components. 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 a few ideas on selecting the best cover. 

Avoid Full Covers

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

Complete AC covers can trap water inside your unit, potentially eating away at metal pieces. It could also make your AC an inviting place for rodents, which could sever wires.
