Do I Need to Cover My Air Conditioner?

With cold weather coming in Rocky Mount, you may be thinking when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a tough piece of equipment. It’s created to withstand severe weather, including excessive temperatures and relentless precipitation.

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

While installing an air conditioner cover is your own choice, there are two seasons that are good to use 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 lower your system’s airflow. Diminished airflow means your air conditioning unit works harder and may use more electricity to cool your home.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from Davis Heating & Air Conditioning heating and cooling professionals can help. We’ll clean and lubricate your unit, and take a close look at critical parts. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap water inside your system, potentially corroding metal components. It could also make your system a welcoming area for vermin, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers block air, which could cause condensation 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 heavy snow is on the way. Snow and ice that build up inside your air conditioner can melt and refreeze, breaking condenser coils and reducing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your air conditioner if a severe storm is approaching in Rocky Mount. Hail can critically damage your system’s coils, altering efficiency.
