Do I Need to Cover My Air Conditioner?

With cold weather approaching in Marshalltown, you may be questioning when you should cover your outdoor air conditioner. Of if you have to cover it at all.

Your AC unit is a strong piece of equipment. It’s created to resist bad weather, including extreme temperatures and relentless precipitation.

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

While using an air conditioner cover is your own choice, there are two seasons that are good to use a cover for a lengthy period of time—fall and summer.  

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

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from B & G HVAC heating and cooling professionals can help. We’ll clean and lubricate your system, and take a close look at important pieces. This often allows us to identify problems 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 a couple suggestions on selecting the ideal cover. 

Avoid Full Covers

To keep air moving, a protective air conditioner cover should only surround the top of your unit and several inches on the side.

Complete AC covers can trap moisture inside your system, potentially corroding metal components. It could also make your air conditioner an inviting home for rodents, which could eat through wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know heavy snow is approaching. Snow and ice that collect 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 AC if a bad storm is coming in Marshalltown. Hail can severely damage your system’s coils, affecting efficiency.
