With cold weather coming in Winnipeg, 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 strong piece of equipment. It’s engineered to resist inclement} weather, including extreme temperatures and relentless precipitation.

Sometimes covers do more harm than good because they can trap water. Extra wetness inside your equipment can cause internal parts to rust or become moldy.

While putting on an air conditioner cover is a personal choice, there are two seasons that are ideal 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 obstruct your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more electricity to cool your house.

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Kirkfield Heating & Air Conditioning heating and cooling professionals can help. We’ll clean and lubricate your system, and examine important pieces. This often allows us to spot issues 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 circulating, a protective air conditioner cover should only surround the top of your unit and a couple of inches on the side.

Complete AC covers can trap water inside your unit, potentially rusting metal components. It could also make your AC an inviting place for animals, which could sever wires.
