Do I Need to Cover My Air Conditioner?

With cold weather approaching in Hattiesburg, you may be wondering when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a strong piece of equipment. It’s created to take on inclement weather, including intense temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap water. Too much wetness inside your equipment can cause internal parts to rust or turn moldy.

While putting on an air conditioner cover is a personal choice, there are two seasons that are great 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 build up and lower your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more electricity to cool your house.

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Oak Grove 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 spot issues before they begin.

How to Choose an Air Conditioner Cover

If you come to the conclusion 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 few inches on the side.

Full AC covers can trap condensation inside your unit, potentially corroding metal parts. It could also make your system a welcoming place for animals, 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 snowstorm is approaching. Snow and ice that build up inside your AC can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your air conditioner if a strong storm is coming in Hattiesburg. Hail can severely damage your system’s exterior, impacting efficiency.
