With cold weather on the horizon in Manassas, 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 tough piece of equipment. It’s designed to resist severe weather, including excessive temperatures and heavy precipitation.

Sometimes covers create more issues because they can trap condensation. Too much wetness inside your unit can cause internal components to rust or get moldy.

While using an air conditioner cover is an individual choice, there are two periods that are good to use 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 build up and lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more electricity to cool your residence.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple tips on selecting the right cover.

Avoid Full Covers

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

Total AC covers can trap moisture inside your equipment, potentially eating away at metal components. It could also make your air conditioner a welcoming home for rodents, which could sever wires.
