Do I Need to Cover My Air Conditioner?

With cold weather coming in Derby, 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 tough piece of equipment. It’s designed to take on severe weather, including intense temperatures and heavy precipitation.

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

While using an air conditioner cover is a personal choice, there are two seasons that are ideal for using a cover for an extended 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. Diminished airflow means your air conditioning unit works more and may use more energy to cool your home.

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Giordanos Heating and Air Conditioning heating and cooling experts can help. We’ll clean and lubricate your system, and examine important components. This often allows us to identify 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 couple suggestions on selecting the ideal cover. 

Avoid Full Covers

To keep air moving, 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 moisture inside your system, potentially corroding metal parts. It could also make your AC an inviting area for animals, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers stop air, which could cause water to build up inside your unit. The best type of fabric is one that allows airflow, 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 blizzard is on the way. Snow and ice that accumulate inside your system 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 system if a strong storm is imminent in Derby. Hail can severely damage your system’s exterior, altering efficiency.
