Do I Need to Cover My Air Conditioner?

October 18, 2019

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

Your AC unit is a strong piece of equipment. It’s created to take on severe weather, including extreme temperatures and torrential precipitation.

Sometimes covers create more issues, because they can trap water. Too much wetness inside your system can cause internal components to rust or turn moldy.

While installing an air conditioner cover is an individual choice, there are two times of year that are good to use a cover for a lengthy period of time—fall and summer.  

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

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from North Mechanical Heating and Cooling heating and cooling professionals can help. We’ll clean and lubricate your equipment, and examine essential parts. This often allows us to identify trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple tips on picking the best cover. 

Avoid Full Covers

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

Complete AC covers can trap water inside your system, potentially corroding metal components. It could also make your air conditioner an inviting place for vermin, which could sever wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers stop air, which could cause condensation to build up inside your unit. The best type of fabric is one that’s breathable, like canvas or mesh.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is approaching. Snow and ice that build up inside your system can melt and refreeze, damaging condenser coils and lowering efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your air conditioner if a bad storm is approaching in Payson. Hail can critically damage your system’s fins, altering efficiency.
