Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Suffolk/Nassau County, 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 tough piece of equipment. It’s created to resist severe weather, including intense temperatures and heavy precipitation.

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

While putting on an air conditioner cover is your own choice, there are two times of year 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 accumulate and block your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more electricity to cool your residence.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from Airmax Long Island Inc heating and cooling experts can help. We’ll clean and lubricate your system, and inspect essential parts. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few tips on picking the ideal cover. 

Avoid Full Covers

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

Complete AC covers can trap moisture inside your unit, potentially rusting metal parts. It could also make your air conditioner a cozy place for animals, which could eat through wires.
