Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in Zelienople, you may be wondering 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 designed to withstand severe weather, including intense temperatures and torrential precipitation.

Sometimes covers cause more problems, because they can trap condensation. Extra wetness inside your system can cause internal parts to rust or turn moldy.

While installing an air conditioner cover is your own choice, there are two times of year that are ideal for using 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 build up and lower your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more energy to cool your residence.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Knoechel Heating Company heating and cooling technicians can help. We’ll clean and lubricate your unit, and examine essential parts. This often allows us to identify issues before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a couple suggestions on choosing the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap moisture inside your system, potentially rusting metal parts. It could also make your AC a cozy area for vermin, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers impede air, which could cause water to build up inside your unit. The best type of fabric 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 on the way. Snow and ice that build up inside your system 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 AC if a bad storm is approaching in Zelienople. Hail can severely damage your system’s exterior, impacting efficiency.
