Do I Need to Cover My Air Conditioner?

With cold weather approaching in Waterloo, 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 tough piece of equipment. It’s designed to take on bad weather, including extreme temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap moisture. Too much wetness inside your equipment can cause internal parts 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 lengthy 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 residence.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from Cronin-Verheul Heating & A/C Ltd heating and cooling technicians can help. We’ll clean and lubricate your unit, and examine critical components. This often allows us to pinpoint trouble 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 several ideas on choosing the ideal 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.

Complete AC covers can trap moisture inside your unit, potentially corroding metal components. It could also make your system an inviting place for animals, which could chew wires.
