Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Derby, 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 tough piece of equipment. It’s created to resist severe weather, including extreme temperatures and heavy precipitation.

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

While using an air conditioner cover is a personal 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 lower your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more electricity to cool your home.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Giordanos Heating and Air Conditioning heating and cooling professionals can help. We’ll clean and lubricate your system, and inspect important components. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple suggestions on selecting the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your equipment, potentially rusting metal parts. It could also make your AC an inviting place 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 on the way. Snow and ice that build up inside your system can melt and refreeze, damaging condenser coils and reducing efficiency.
