Do I Need to Cover My Air Conditioner?

With cold weather coming in Keokuk, you may be thinking 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 designed to take on bad weather, including excessive temperatures and relentless precipitation.

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

While putting on an air conditioner cover is a personal choice, there are two periods that are great 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 obstruct your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more energy to cool your residence.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from WM J Kraus & Son heating and cooling experts can help. We’ll clean and lubricate your unit, and inspect critical parts. This often allows us to identify problems 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 choosing the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap moisture inside your unit, potentially rusting metal parts. It could also make your AC a cozy home for rodents, which could sever wires.

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 accumulate inside your system can melt and refreeze, harming condenser coils and decreasing efficiency.

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