Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Eastland, you may be thinking 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 created to take on inclement weather, including extreme temperatures and heavy precipitation.

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

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

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

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from J & J Air Conditioning heating and cooling experts can help. We’ll clean and lubricate your unit, and inspect important pieces. This often allows us to identify 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 best cover. 

Avoid Full Covers

To keep air flowing, 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 condensation inside your system, potentially rusting metal components. It could also make your air conditioner an inviting home for rodents, which could sever wires.

Cover Your Air Conditioner Before Severe Weather

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

Although it’s not always possible to predict a hailstorm, you can temporarily cover your AC if a severe storm is coming in Eastland. Hail can severely damage your system’s fins, impacting efficiency.
