Do I Need to Cover My Air Conditioner?

With cold weather approaching in Winnipeg, 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 tough piece of equipment. It’s designed to withstand severe weather, including excessive temperatures and relentless precipitation.

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

While using 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 debris during those seasons—grass clippings, twigs and leaves—can build up and lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more energy to cool your home.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Kirkfield Heating & Air Conditioning heating and cooling professionals can help. We’ll clean and lubricate your equipment, and take a close look at critical parts. This often allows us to spot trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple suggestions on picking the best cover. 

Avoid Full Covers

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

Full AC covers can trap condensation inside your unit, potentially corroding metal components. It could also make your AC a welcoming area for rodents, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers block air, which could cause moisture to build up inside your system. The best type of cloth is one that allows airflow, like canvas or mesh.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is coming. Snow and ice that collect inside your AC can melt and refreeze, harming condenser coils and decreasing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your system if a strong storm is coming in Winnipeg. Hail can seriously damage your system’s exterior, impacting efficiency.
