Do I Need to Cover My Air Conditioner?

With cold weather coming in Marshalltown, 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 engineered to resist bad weather, including extreme temperatures and heavy precipitation.

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

While installing an air conditioner cover is your own choice, there are two seasons that are good to use a cover for a lengthy 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. Diminished airflow means your air conditioning unit works more and may use more electricity to cool your residence.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from Kapaun & Brown Inc. heating and cooling professionals can help. We’ll clean and lubricate your system, and take a close look at essential pieces. This often allows us to pinpoint problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap moisture inside your unit, potentially eating away at metal parts. It could also make your system a cozy home 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 heavy snow is on the way. Snow and ice that collect inside your AC 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 air conditioner if a bad storm is imminent in Marshalltown. Hail can seriously damage your system’s fins, affecting efficiency.
