Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Laurel, you may be questioning 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 take on severe weather, including intense temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Extra wetness inside your system can cause internal pieces to rust or become moldy.

While installing an air conditioner cover is your own choice, there are two periods that are great for using a cover for a lengthy period of time—fall and summer.  

That’s because yard rubbish 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 more and may use more energy to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from H&C Heating and Cooling heating and cooling experts can help. We’ll clean and lubricate your equipment, and examine important parts. 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 suggestions on selecting the best cover. 

Avoid Full Covers

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

Complete AC covers can trap water inside your equipment, potentially corroding metal parts. It could also make your air conditioner a welcoming area for animals, which could eat through wires.

Cover Your Air Conditioner Before Severe Weather
