Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Hasbrouck Heights, you may be questioning 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 designed to resist bad weather, including extreme temperatures and heavy precipitation.

Sometimes covers do more harm than good, because they can trap moisture. Additional wetness inside your equipment can cause internal components to rust or turn moldy.

While using an air conditioner cover is your own choice, there are two seasons 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 pile up and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more electricity to cool your house.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from ACE Solutions heating and cooling experts can help. We’ll clean and lubricate your unit, and take a close look at important components. This often allows us to pinpoint problems 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 ideal cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your unit, potentially rusting metal components. It could also make your air conditioner an inviting area for vermin, which could sever wires.
