Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Monroe, you may be thinking when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a sturdy piece of equipment. It’s designed to withstand bad weather, including extreme temperatures and relentless precipitation.

Sometimes covers create more issues, because they can trap moisture. Additional wetness inside your system can cause internal parts to rust or become moldy.

While installing an air conditioner cover is your own choice, there are two periods that are great 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 pile up and obstruct your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more electricity to cool your home.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Lanz Furnace and Fireplace heating and cooling professionals can help. We’ll clean and lubricate your unit, and take a close look at critical parts. This often allows us to spot 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 picking the right cover. 

Avoid Full Covers

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

Total AC covers can trap moisture inside your system, potentially eating away at metal parts. It could also make your system an inviting area for vermin, which could chew wires.
