Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Columbus, you may be wondering when you should cover your outdoor air conditioner. Of if you need 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 moisture. Too much wetness inside your system can cause internal parts to rust or become moldy.

While using an air conditioner cover is a personal choice, there are two times of year that are ideal for using a cover for an extended period of time—fall and summer.  

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

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from Wolfe & Sons Heating and Cooling heating and cooling technicians can help. We’ll clean and lubricate your unit, and take a close look at important pieces. 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 several tips on selecting the right cover. 

Avoid Full Covers

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

Complete AC covers can trap condensation inside your equipment, potentially rusting metal pieces. It could also make your AC a cozy home for animals, 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 approaching. Snow and ice that accumulate inside your air conditioner can melt and refreeze, harming condenser coils and lowering efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your AC if a severe storm is imminent in Columbus. Hail can seriously damage your system’s coils, impacting efficiency.
