Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Franklin Lakes, you may be wondering 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 engineered to resist inclement weather, including excessive temperatures and relentless precipitation.

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

While using an air conditioner cover is a personal choice, there are two times of year that are good to use 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 block your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more energy to cool your house.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Total Comfort heating and cooling professionals can help. We’ll clean and lubricate your equipment, and take a close look at important components. This often allows us to spot trouble before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap moisture inside your system, potentially corroding metal parts. It could also make your AC a welcoming place for rodents, 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 snowstorm is approaching. Snow and ice that build up inside your air conditioner can melt and refreeze, breaking condenser coils and lowering efficiency.
