With cold weather on the horizon in Milwaukee, you may be thinking 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 designed to resist inclement weather, including intense temperatures and torrential precipitation.

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

While using an air conditioner cover is a personal choice, there are two seasons that are good to use a cover for an extended period of time—fall and summer.

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can pile up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works more and may use more electricity to cool your house.

Choosing the Right Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are several ideas on selecting the best cover.

Avoid Full Covers

To keep air flowing, a protective air conditioner cover should only encompass the top of your unit and a few inches on the side.

Complete AC covers can trap water inside your equipment, potentially rusting metal parts. It could also make your air conditioner a cozy home for animals, 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 coming. Snow and ice that build up inside your AC can melt and refreeze, breaking condenser coils and reducing efficiency.
