Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Huntingburg, 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 withstand bad weather, including intense temperatures and relentless precipitation.

Sometimes covers create more issues, because they can trap water. Additional wetness inside your equipment can cause internal components to rust or turn moldy.

While putting on an air conditioner cover is an individual choice, there are two times of year that are good to use a cover for an extended period of time—fall and summer.  

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can build up and block your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more power to cool your residence.

Seeking other ways to make your air conditioner run efficiently? Routine AC maintenance from Dearing's Service & Solutions heating and cooling experts can help. We’ll clean and lubricate your system, and take a close look at important parts. This often allows us to spot issues before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple ideas on choosing the best cover. 

Avoid Full Covers

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

Complete AC covers can trap condensation inside your system, potentially eating away at metal components. It could also make your system a cozy area 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 a snowstorm is on the way. Snow and ice that build up inside your air conditioner can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your system if a bad storm is approaching in Huntingburg. Hail can critically damage your system’s fins, affecting efficiency.
