Do I Need to Cover My Air Conditioner?

With cold weather approaching in Rochester, you may be wondering 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 created to resist bad weather, including intense temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap water. Extra wetness inside your unit can cause internal components to rust or become 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 lengthy period of time—fall and summer.  

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

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few suggestions on picking the best cover. 

Avoid Full Covers

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

Complete AC covers can trap water inside your unit, potentially eating away at metal pieces. It could also make your AC a cozy home for vermin, which could eat through wires.
