Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Tuscaloosa, you may be thinking 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 designed to withstand severe weather, including excessive temperatures and heavy precipitation.

Sometimes covers create more issues, because they can trap water. Too much wetness inside your system can cause internal pieces to rust or become moldy.

While putting on an air conditioner cover is your own choice, there are two periods that are ideal for using a cover for an extended period of time—fall and summer.  

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

Seeking other ways to make your air conditioner run efficiently? Routine AC maintenance from KDM Service Corporation heating and cooling technicians can help. We’ll clean and lubricate your equipment, and examine critical 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 several ideas on selecting the ideal cover. 

Avoid Full Covers

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

Full AC covers can trap condensation inside your system, potentially rusting metal components. It could also make your AC a welcoming place for animals, which could sever wires.
