Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Pella, 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 inclement weather, including extreme temperatures and torrential precipitation.

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

While putting on an air conditioner cover is your own 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 waste 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 power to cool your residence.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Van Haaften Plumbing & Heating heating and cooling technicians can help. We’ll clean and lubricate your system, and take a close look at critical pieces. This often allows us to pinpoint trouble 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 selecting the right cover. 

Avoid Full Covers

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

Total AC covers can trap condensation inside your unit, potentially rusting metal parts. It could also make your AC a cozy area for vermin, which could sever wires.

Plastic or vinyl covers stop air, which could cause condensation to build up inside your air conditioner. The best type of material 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 heavy snow is approaching. Snow and ice that build up inside your system can melt and refreeze, breaking condenser coils and lowering efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your air conditioner if a severe storm is approaching in Pella. Hail can seriously damage your system’s coils, altering efficiency.
