Do I Need to Cover My Air Conditioner?

With cold weather on the horizon in Ballwin, you may be questioning when you should cover your outdoor air conditioner. Of if you should even cover it at all.

Your AC unit is a strong piece of equipment. It’s designed to take on severe weather, including intense temperatures and torrential precipitation.

Sometimes covers cause more problems, because they can trap moisture. Extra wetness inside your unit can cause internal pieces to rust or become moldy.

While putting on an air conditioner cover is an individual choice, there are two times of year that are great for using a cover for an extended period of time—fall and summer.  

That’s because yard waste during those seasons—grass clippings, twigs and leaves—can accumulate and lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more energy to cool your home.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from Holiday Heating & Air Conditioning heating and cooling experts can help. We’ll clean and lubricate your system, and examine essential components. This often allows us to pinpoint trouble 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 tips on picking the best cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your unit, potentially eating away at metal parts. It could also make your air conditioner a cozy home for rodents, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers stop air, which could cause water to build up inside your unit. The best type of cloth is one that’s breathable, like canvas or mesh.

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 air conditioner can melt and refreeze, harming condenser coils and lowering efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your system if a severe storm is coming in Ballwin. Hail can seriously damage your system’s coils, altering efficiency.
