Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Macon, 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 engineered to resist bad weather, including extreme temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap moisture. Too much wetness inside your system can cause internal components to rust or become 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 rubbish during those seasons—grass clippings, twigs and leaves—can accumulate and block your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more energy to cool your house.

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Air Temperature Control heating and cooling technicians can help. We’ll clean and lubricate your system, and examine essential 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 suggestions on selecting the ideal cover. 

Avoid Full Covers

To keep air circulating, a protective air conditioner cover should only encompass the top of your system and a few inches on the side.

Total AC covers can trap condensation inside your unit, potentially eating away at metal components. It could also make your system a cozy 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 collect inside your air conditioner can melt and refreeze, breaking condenser coils and reducing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your AC if a bad storm is imminent in Macon. Hail can severely damage your system’s coils, impacting efficiency.
