Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Florissant, 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 tough piece of equipment. It’s created to take on severe weather, including intense temperatures and heavy precipitation.

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

While putting on an air conditioner cover is an individual choice, there are two periods that are great 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 pile up and block your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more energy to cool your house.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap condensation inside your unit, potentially eating away at metal pieces. It could also make your AC a welcoming 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 heavy snow is on the way. Snow and ice that accumulate inside your system can melt and refreeze, breaking condenser coils and decreasing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your air conditioner if a severe storm is approaching in Florissant. Hail can severely damage your system’s coils, affecting efficiency.
