Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Middletown, 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 tough piece of equipment. It’s engineered to withstand bad weather, including excessive temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap moisture. Too much wetness inside your system can cause internal pieces to rust or get moldy.

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

That’s because yard rubbish during those seasons—grass clippings, twigs and leaves—can build up and lower your system’s airflow. Reduced airflow means your air conditioning unit works harder and may use more power to cool your house.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from SchagrinGAS Company heating and cooling technicians can help. We’ll clean and lubricate your unit, and inspect critical components. This often allows us to spot problems before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are several suggestions on selecting the best cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your equipment, potentially eating away at metal components. It could also make your system a welcoming area for rodents, which could sever 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 build up inside your air conditioner can melt and refreeze, harming condenser coils and reducing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your air conditioner if a strong storm is approaching in Middletown. Hail can severely damage your system’s exterior, impacting efficiency.
