With cold weather approaching in Los Angeles, you may be wondering when you should cover your outdoor air conditioner. Of if you have to cover it at all.

Your AC unit is a sturdy piece of equipment. It’s created to resist severe} weather, including extreme temperatures and relentless precipitation.

Sometimes covers cause more problems because they can trap water. Extra wetness inside your system can cause internal components to rust or turn moldy.

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

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can build up and block your system’s airflow. Diminished airflow means your air conditioning unit works harder and may use more electricity to cool your residence.

How to Choose an Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a few suggestions on choosing the right cover.

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

Full AC covers can trap condensation inside your system, potentially corroding metal parts. It could also make your system an inviting place for vermin, which could eat through wires.
