Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Hodgenville, you may be questioning 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 resist bad weather, including intense temperatures and relentless precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Additional wetness inside your equipment can cause internal pieces to rust or get moldy.

While installing an air conditioner cover is your own choice, there are two times of year that are great for using a cover for a lengthy period of time—fall and summer.  

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

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Phelps Heating & Cooling heating and cooling professionals can help. We’ll clean and lubricate your unit, and examine important parts. This often allows us to spot problems 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 couple tips on selecting the right cover. 

Avoid Full Covers

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

Total AC covers can trap condensation inside your system, potentially corroding metal pieces. It could also make your system a cozy home for vermin, which could chew wires.
