Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Katy, you may be thinking 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 resist severe weather, including intense temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap water. Extra wetness inside your equipment can cause internal pieces to rust or become moldy.

While using an air conditioner cover is your own choice, there are two periods that are good to use a cover for a long period of time—fall and summer.  

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can build up and lower your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more energy to cool your house.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Goode Bros AC & Heating heating and cooling professionals can help. We’ll clean and lubricate your equipment, and examine critical parts. This often allows us to identify issues 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 tips on selecting the best cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your equipment, potentially rusting metal pieces. It could also make your system an inviting area for animals, which could chew wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a blizzard is coming. Snow and ice that build up inside your system 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 AC if a strong storm is coming in Katy. Hail can seriously damage your system’s fins, affecting efficiency.
