Do I Need to Cover My Air Conditioner?

With cold weather coming in Florissant, you may be questioning when you should cover your outdoor air conditioner. Of if you should even cover it at all.

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

Sometimes covers create more issues, because they can trap moisture. Additional wetness inside your system can cause internal parts to rust or turn moldy.

While using an air conditioner cover is an individual choice, there are two periods that are good to use a cover for a long period of time—fall and summer.  

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

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from B & B Heating & Cooling heating and cooling experts can help. We’ll clean and lubricate your system, and take a close look at essential components. This often allows us to spot trouble 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 a few suggestions on picking the right cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your unit, potentially rusting metal components. It could also make your AC an inviting place for rodents, which could eat through wires.

Plastic or vinyl covers stop air, which could cause water to build up inside your air conditioner. The best type of material is one that lets in air, like canvas or mesh.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is on the way. Snow and ice that build up inside your air conditioner can melt and refreeze, damaging condenser coils and reducing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your AC if a strong storm is coming in Florissant. Hail can severely damage your system’s fins, altering efficiency.
