Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Logan, 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 extreme temperatures and heavy precipitation.

Sometimes covers cause more problems, because they can trap water. Extra wetness inside your system can cause internal components to rust or turn moldy.

While using an air conditioner cover is your own 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 build up and obstruct your system’s airflow. Reduced airflow means your air conditioning unit works harder and may use more energy to cool your residence.

Looking for other ways to make your air conditioner run efficiently? Routine AC maintenance from Western Mechanical, Inc. heating and cooling professionals can help. We’ll clean and lubricate your system, and take a close look at critical parts. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap water inside your unit, potentially eating away at metal parts. It could also make your system a cozy home for animals, which could eat through wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is approaching. 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 predict a hailstorm, you can temporarily cover your air conditioner if a severe storm is imminent in Logan. Hail can seriously damage your system’s fins, impacting efficiency.
