With cold weather on the horizon in Auburn and Opelika, 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 sturdy piece of equipment. It’s created to resist inclement weather, including excessive temperatures and relentless precipitation.

Sometimes covers create more issues because they can trap water. Extra wetness inside your unit can cause internal components to rust or become moldy.

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

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

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Farnell Mechanical, Inc. heating and cooling experts can help. We’ll clean and lubricate your equipment, and inspect important parts. This often allows us to spot issues before they begin.

How to Find Your Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a few suggestions on picking the right cover.

Avoid Full Covers

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

Full AC covers can trap moisture inside your system, potentially rusting metal parts. It could also make your air conditioner a cozy place for animals, which could chew wires.
