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

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

Sometimes covers create more issues because they can trap water. Additional wetness inside your equipment can cause internal components to rust or become moldy.

While using an air conditioner cover is an individual choice, there are two periods that are good to use 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 electricity to cool your residence.

Choosing the Right Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a couple tips on picking the right cover.

Avoid Full Covers

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

Complete AC covers can trap water inside your system, potentially rusting metal components. It could also make your air conditioner a cozy area for vermin, which could eat through 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 system can melt and refreeze, damaging condenser coils and reducing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your system if a strong storm is imminent in Los Angeles. Hail can seriously damage your system’s exterior, impacting efficiency.
