Do I Need to Cover My Air Conditioner?

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

Your AC unit is a sturdy piece of equipment. It’s designed to take on inclement weather, including intense temperatures and relentless precipitation.

Sometimes covers create more issues, because they can trap moisture. Too much wetness inside your system can cause internal components to rust or get 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 long period of time—fall and summer.  

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can build up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more energy to cool your house.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Full AC covers can trap condensation inside your system, potentially rusting metal parts. It could also make your system an inviting area for vermin, which could chew wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is coming. Snow and ice that build up inside your AC can melt and refreeze, harming condenser coils and lowering efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your AC if a strong storm is approaching in St. Louis. Hail can critically damage your system’s coils, affecting efficiency.
