Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Genoa, 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 created to withstand inclement weather, including extreme temperatures and torrential precipitation.

Sometimes covers create more issues, because they can trap moisture. Too much wetness inside your unit can cause internal components to rust or turn moldy.

While installing an air conditioner cover is your own choice, there are two seasons that are great for using 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. Diminished airflow means your air conditioning unit works more and may use more electricity to cool your house.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Assured Appliance and Heating & Air heating and cooling professionals can help. We’ll clean and lubricate your system, and inspect critical pieces. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Full AC covers can trap moisture inside your system, potentially eating away at metal components. It could also make your air conditioner a welcoming area for rodents, 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 a blizzard is coming. Snow and ice that accumulate inside your AC can melt and refreeze, harming condenser coils and decreasing efficiency.
