With cold weather coming in Frederick, you may be questioning 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 severe} weather, including extreme temperatures and torrential precipitation.
Sometimes covers cause more problems because they can trap moisture. Extra wetness inside your system can cause internal parts to rust or turn moldy.
While installing an air conditioner cover is a personal choice, there are two times of year that are ideal 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 pile up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more electricity to cool your house.
