With cold weather approaching in Cambridge, 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 resist inclement weather, including excessive temperatures and relentless precipitation.

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

While using an air conditioner cover is a personal choice, there are two periods that are great for using a cover for a long period of time—fall and summer.

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

Choosing the Right Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few suggestions on picking the right cover.

Avoid Full Covers

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

Total AC covers can trap condensation inside your unit, potentially eating away at metal components. It could also make your system an inviting area 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 heavy snow is approaching. Snow and ice that accumulate inside your AC can melt and refreeze, breaking condenser coils and lowering efficiency.
