Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Pflugerville, you may be thinking when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a sturdy piece of equipment. It’s designed to take on bad weather, including excessive temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap moisture. Too much wetness inside your unit can cause internal parts to rust or get moldy.

While using an air conditioner cover is your own 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 debris during those seasons—grass clippings, twigs and leaves—can accumulate and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works more and may use more power to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Evenaire Heating & Air Conditioning heating and cooling experts can help. We’ll clean and lubricate your equipment, and inspect important parts. This often allows us to pinpoint issues before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are several tips on picking the best cover. 

Avoid Full Covers

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

Complete AC covers can trap condensation inside your system, potentially rusting metal parts. It could also make your AC an inviting area for animals, which could eat through wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is coming. Snow and ice that build up inside your air conditioner can melt and refreeze, harming condenser coils and reducing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your AC if a strong storm is approaching in Pflugerville. Hail can severely damage your system’s exterior, impacting efficiency.
