Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Brookfield, you may be questioning 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 engineered to withstand bad weather, including extreme temperatures and relentless precipitation.

Sometimes covers create more issues, because they can trap moisture. Too much wetness inside your equipment can cause internal components to rust or get moldy.

While putting on an air conditioner cover is an individual choice, there are two periods that are good to use a cover for a long period of time—fall and summer.  

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can pile up and block your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more energy to cool your residence.

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Central Air LLC heating and cooling technicians can help. We’ll clean and lubricate your equipment, and take a close look at important components. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Full AC covers can trap water inside your system, potentially corroding metal pieces. It could also make your air conditioner an inviting place for vermin, which could eat through 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 material is one that allows airflow, 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 coming. 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 predict a hailstorm, you can temporarily cover your system if a bad storm is coming in Brookfield. Hail can severely damage your system’s fins, impacting efficiency.
