Do I Need to Cover My Air Conditioner?

With cold weather on the horizon in Huntsville, 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 tough piece of equipment. It’s designed to withstand bad weather, including extreme temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap water. Too much wetness inside your equipment can cause internal components to rust or turn moldy.

While putting on an air conditioner cover is a personal choice, there are two seasons that are good to use a cover for an extended period of time—fall and summer.  

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

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from All Weather Heating & Air Conditioning Inc heating and cooling technicians can help. We’ll clean and lubricate your unit, and examine important components. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple tips on picking the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your equipment, potentially rusting metal pieces. It could also make your air conditioner an inviting place for rodents, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers block air, which could cause water to build up inside your air conditioner. The best type of cloth is one that’s breathable, like canvas or mesh.

Cover Your Air Conditioner Before Severe Weather

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

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your AC if a severe storm is imminent in Huntsville. Hail can severely damage your system’s fins, impacting efficiency.
