With cold weather on the horizon in Tucson, 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 sturdy piece of equipment. It’s engineered to resist severe} weather, including extreme temperatures and heavy precipitation.

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

While putting on an air conditioner cover is an individual choice, there are two seasons that are ideal for using a cover for an extended period of time—fall and summer.

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

Looking for other ways to make your air conditioner run efficiently? Routine AC maintenance from Ambient Air heating and cooling experts can help. We’ll clean and lubricate your equipment, and examine essential components. This often allows us to spot problems before they begin.

How to Choose an Air Conditioner Cover

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