Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Pacheco, you may be thinking when you should cover your outdoor air conditioner. Of if you should even cover it at all.

Your AC unit is a sturdy piece of equipment. It’s engineered to resist bad weather, including intense temperatures and torrential precipitation.

Sometimes covers cause more problems, because they can trap condensation. Too much wetness inside your equipment can cause internal components to rust or get moldy.

While using an air conditioner cover is your own choice, there are two seasons that are good to use a cover for a long period of time—fall and summer.  

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

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Clean Air HVAC heating and cooling professionals can help. We’ll clean and lubricate your unit, and inspect critical pieces. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

To keep air circulating, a protective air conditioner cover should only enclose the top of your system and a few inches on the side.

Complete AC covers can trap moisture inside your unit, potentially eating away at metal components. It could also make your system an inviting area for vermin, which could eat through wires.
