Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Magnolia, you may be thinking when you should cover your outdoor air conditioner. Of if you should even cover it at all.

Your AC unit is a tough piece of equipment. It’s engineered to withstand severe weather, including extreme temperatures and torrential precipitation.

Sometimes covers create more issues, because they can trap moisture. Additional 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 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 obstruct your system’s airflow. Diminished airflow means your air conditioning unit works more and may use more electricity to cool your residence.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from JTech Mechanical heating and cooling professionals can help. We’ll clean and lubricate your system, and examine important pieces. This often allows us to identify issues before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a couple tips on choosing the right cover. 

Avoid Full Covers

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

Full AC covers can trap water inside your unit, potentially corroding metal parts. It could also make your air conditioner a cozy home for vermin, which could eat through wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers impede air, which could cause moisture to build up inside your unit. The best type of material 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 a blizzard is approaching. Snow and ice that accumulate inside your air conditioner 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 bad storm is approaching in Magnolia. Hail can critically damage your system’s exterior, altering efficiency.
