Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Safford, 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 sturdy 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 condensation. Additional wetness inside your equipment can cause internal components to rust or get moldy.

While putting on an air conditioner cover is your own choice, there are two periods that are good to use a cover for a long period of time—fall and summer.  

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can accumulate and lower your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more electricity to cool your home.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from B&D Air Conditioning heating and cooling technicians can help. We’ll clean and lubricate your system, and examine critical pieces. This often allows us to spot trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple ideas on choosing the best cover. 

Avoid Full Covers

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

Total AC covers can trap moisture inside your unit, potentially eating away at metal components. It could also make your air conditioner a welcoming place for animals, which could eat through wires.
