With cold weather coming in Mankato area, you may be wondering when you should cover your outdoor air conditioner. Of if you should even cover it at all.

Your AC unit is a sturdy piece of equipment. It’s designed to resist bad} weather, including excessive temperatures and heavy precipitation.

Sometimes covers cause more problems because they can trap water. Too much wetness inside your equipment can cause internal parts to rust or turn moldy.

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

That’s because yard rubbish 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 power to cool your house.

Full AC covers can trap moisture inside your system, potentially eating away at metal pieces. It could also make your system a cozy place for animals, which could eat through wires.
