Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Rock Hill, you may be wondering 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 inclement weather, including excessive temperatures and relentless precipitation.

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

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

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

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from US Air Heating and Cooling heating and cooling technicians can help. We’ll clean and lubricate your unit, and examine essential pieces. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few suggestions on picking the ideal cover. 

Avoid Full Covers

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

Complete AC covers can trap condensation inside your unit, potentially corroding metal pieces. It could also make your air conditioner a cozy area for animals, which could sever wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a blizzard is approaching. Snow and ice that build up inside your air conditioner can melt and refreeze, breaking condenser coils and decreasing efficiency.
