With cold weather approaching in Pella, 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 tough piece of equipment. It’s designed to resist bad weather, including intense temperatures and heavy precipitation.

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

While using an air conditioner cover is an individual 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 rubbish during those seasons—grass clippings, twigs and leaves—can accumulate and block your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more electricity to cool your home.

Choosing the Right Air Conditioner Cover

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

Avoid Full Covers

To keep air moving, a protective air conditioner cover should only enclose the top of your equipment and several inches on the side.

Complete AC covers can trap water inside your equipment, potentially corroding metal components. It could also make your air conditioner a welcoming place for animals, which could chew wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is coming. Snow and ice that accumulate inside your air conditioner can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your air conditioner if a bad storm is approaching in Pella. Hail can seriously damage your system’s fins, altering efficiency.
