Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Wyandotte, you may be thinking 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 designed to resist bad weather, including excessive temperatures and relentless precipitation.

Sometimes covers create more issues, because they can trap moisture. Extra wetness inside your system can cause internal parts to rust or get moldy.

While installing an air conditioner cover is a personal 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 waste during those seasons—grass clippings, twigs and leaves—can pile up and block your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more electricity to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Gee & Missler Heating & Air Conditioning heating and cooling technicians can help. We’ll clean and lubricate your unit, and examine critical pieces. This often allows us to identify issues 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 choosing the right cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your unit, potentially eating away at metal components. It could also make your air conditioner an inviting area for animals, which could chew wires.

Cover Your Air Conditioner Before Severe Weather

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

Although it’s not always possible to expect a hailstorm, you can temporarily cover your system if a severe storm is approaching in Wyandotte. Hail can critically damage your system’s fins, affecting efficiency.
