With cold weather on the horizon in Derby, 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 tough 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. Additional wetness inside your equipment can cause internal parts to rust or become moldy.

While installing an air conditioner cover is your own choice, there are two periods that are great 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 pile up and lower your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more energy to cool your house.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Giordanos Heating and Air Conditioning heating and cooling experts can help. We’ll clean and lubricate your equipment, and inspect essential components. This often allows us to identify trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple suggestions on selecting the ideal cover.

Avoid Full Covers

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

Full AC covers can trap moisture inside your unit, potentially corroding metal components. It could also make your system a welcoming place for vermin, which could eat through wires.
