Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Mechanicsburg, 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 designed to resist inclement weather, including extreme temperatures and relentless precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Additional wetness inside your unit can cause internal parts to rust or get moldy.

While using an air conditioner cover is a personal choice, there are two periods that are ideal for using a cover for a long period of time—fall and summer.  

That’s because yard rubbish during those seasons—grass clippings, twigs and leaves—can pile up and block your system’s airflow. Diminished airflow means your air conditioning unit works more and may use more power to cool your home.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from H & H Service Company heating and cooling professionals can help. We’ll clean and lubricate your unit, and inspect essential components. This often allows us to pinpoint problems before they begin.

How to Choose an Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a few suggestions on choosing the right cover. 

Avoid Full Covers

To keep air moving, a protective air conditioner cover should only encompass the top of your system and a few inches on the side.

Total AC covers can trap water inside your unit, potentially corroding metal parts. It could also make your AC an inviting area for animals, which could sever wires.
