Do I Need to Cover My Air Conditioner?

With cold weather approaching in New Castle, 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 strong piece of equipment. It’s designed to withstand severe weather, including excessive 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 get moldy.

While using an air conditioner cover is a personal choice, there are two times of year that are good to use a cover for an extended 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. Reduced airflow means your air conditioning unit works more and may use more energy to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Central Heating & Plumbing heating and cooling experts can help. We’ll clean and lubricate your equipment, and take a close look at important components. This often allows us to identify issues before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple suggestions on selecting the right cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your unit, potentially corroding metal pieces. It could also make your system a cozy place for vermin, which could eat through wires.

Cover Your Air Conditioner Before Severe Weather
