Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Marshfield, 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 created to resist bad weather, including intense temperatures and relentless precipitation.

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

While installing an air conditioner cover is your own 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 debris during those seasons—grass clippings, twigs and leaves—can build up and lower your system’s airflow. Diminished airflow means your air conditioning unit works more and may use more electricity to cool your house.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from House of Heating Incorporated heating and cooling experts can help. We’ll clean and lubricate your system, and inspect essential parts. This often allows us to spot trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few ideas on picking the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap moisture inside your unit, potentially corroding metal components. It could also make your system an inviting place for rodents, which could sever wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is coming. Snow and ice that build up 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 strong storm is coming in Marshfield. Hail can critically damage your system’s coils, impacting efficiency.
