Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Alliance, you may be thinking 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 created to resist bad weather, including intense temperatures and heavy precipitation.

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

While using an air conditioner cover is an individual choice, there are two periods that are great for using 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 lower your system’s airflow. Reduced airflow means your air conditioning unit works harder and may use more energy to cool your house.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Jack's Heating, Cooling, Stoves & Fireplaces heating and cooling professionals can help. We’ll clean and lubricate your system, and examine critical pieces. This often allows us to spot issues before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Full AC covers can trap condensation inside your equipment, potentially corroding metal components. It could also make your system a welcoming place 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 on the way. Snow and ice that build up inside your AC 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 air conditioner if a severe storm is imminent in Alliance. Hail can severely damage your system’s fins, affecting efficiency.
