Do I Need to Cover My Air Conditioner?

With cold weather coming in Moline, you may be wondering when you should cover your outdoor air conditioner. Of if you have to cover it at all.

Your AC unit is a sturdy piece of equipment. It’s designed to resist severe weather, including intense temperatures and heavy precipitation.

Sometimes covers do more harm than good, because they can trap water. Extra wetness inside your unit can cause internal components to rust or turn moldy.

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

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can accumulate and lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more energy to cool your home.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Freed Heating & Air Conditioning heating and cooling professionals can help. We’ll clean and lubricate your equipment, and take a close look at essential pieces. This often allows us to spot problems before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few ideas on choosing the best cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your unit, potentially eating away at metal parts. It could also make your AC an inviting home for vermin, which could sever wires.

Plastic or vinyl covers impede air, which could cause moisture to build up inside your system. The best type of fabric is one that allows airflow, 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 on the way. Snow and ice that accumulate inside your system can melt and refreeze, damaging condenser coils and lowering efficiency.

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