Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather coming in Fort Lauderdale, 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 tough piece of equipment. It’s designed to take on inclement weather, including intense temperatures and relentless precipitation.

Sometimes covers cause more problems, because they can trap condensation. Additional wetness inside your equipment can cause internal pieces to rust or become moldy.

While installing an air conditioner cover is an individual 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 build up and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works harder and may use more power to cool your house.

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Solar Air Inc. heating and cooling experts can help. We’ll clean and lubricate your unit, and examine essential components. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap water inside your unit, potentially rusting metal components. It could also make your system a cozy 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 coming. Snow and ice that build up inside your AC can melt and refreeze, harming condenser coils and reducing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your air conditioner if a strong storm is coming in Fort Lauderdale. Hail can seriously damage your system’s exterior, impacting efficiency.
