With cold weather on the horizon in Crystal and Twin Cities, you may be wondering when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a sturdy piece of equipment. It’s created to resist inclement} weather, including intense temperatures and relentless precipitation.

Sometimes covers do more harm than good because they can trap moisture. Too much wetness inside your unit can cause internal parts to rust or get moldy.

While installing an air conditioner cover is your own 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 rubbish 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 more and may use more power to cool your house.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are several ideas on choosing the ideal cover.

Total AC covers can trap water inside your unit, potentially eating away at metal components. It could also make your system a cozy area for vermin, which could sever wires.
