Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Oxford, you may be thinking when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a strong piece of equipment. It’s created to withstand bad weather, including excessive temperatures and relentless precipitation.

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

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

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

How to Choose an Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are several suggestions on choosing the ideal cover. 

Avoid Full Covers

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

Complete AC covers can trap water inside your system, potentially rusting metal components. It could also make your AC an inviting area for animals, which could chew wires.
