Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Ronkonkoma, 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 created to take on inclement weather, including intense temperatures and relentless precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Additional wetness inside your equipment can cause internal parts to rust or get moldy.

While installing an air conditioner cover is a personal 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 rubbish during those seasons—grass clippings, twigs and leaves—can pile up and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works harder and may use more energy to cool your house.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Cool Power LLC heating and cooling technicians can help. We’ll clean and lubricate your system, and take a close look at essential parts. This often allows us to pinpoint 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 tips on picking the ideal cover. 

Avoid Full Covers

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

Total AC covers can trap water inside your system, potentially corroding metal components. It could also make your AC an inviting place for vermin, which could chew 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 cloth 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 on the way. Snow and ice that accumulate inside your system can melt and refreeze, breaking condenser coils and reducing efficiency.

Although it’s not always possible to expect a hailstorm, you can temporarily cover your air conditioner if a strong storm is approaching in Ronkonkoma. Hail can severely damage your system’s fins, altering efficiency.
