Do I Need to Cover My Air Conditioner?

With cold weather on the horizon in Ontario, you may be questioning when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a strong piece of equipment. It’s created to take on bad weather, including intense temperatures and heavy precipitation.

Sometimes covers do more harm than good, because they can trap moisture. Extra wetness inside your system can cause internal components to rust or get moldy.

While putting on an air conditioner cover is an individual choice, there are two times of year that are good to use 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 build up and lower your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more energy to cool your home.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Stan's Heating, Inc heating and cooling experts can help. We’ll clean and lubricate your unit, and take a close look at essential components. This often allows us to identify trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide 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 surround the top of your unit and a couple of inches on the side.

Total AC covers can trap condensation inside your equipment, potentially rusting metal parts. It could also make your AC a welcoming home for vermin, 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 accumulate inside your AC can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your AC if a severe storm is imminent in Ontario. Hail can critically damage your system’s coils, altering efficiency.
