Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather on the horizon in Buellton, 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 tough piece of equipment. It’s created to take on severe weather, including excessive temperatures and heavy precipitation.

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

While installing an air conditioner cover is an individual choice, there are two seasons that are ideal for using a cover for an extended period of time—fall and summer.  

That’s because yard waste 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 longer and may use more energy to cool your house.

Wanting other ways to make your air conditioner run efficiently? Regular AC maintenance from Allstar Heating & Air Conditioning heating and cooling professionals can help. We’ll clean and lubricate your equipment, and examine important parts. This often allows us to identify problems before they begin.

How to Choose an Air Conditioner Cover

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

Full AC covers can trap condensation inside your unit, potentially eating away at metal parts. It could also make your AC a welcoming area for vermin, which could sever wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers stop air, which could cause condensation to build up inside your unit. The best type of fabric is one that lets in air, 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 approaching. Snow and ice that accumulate inside your air conditioner can melt and refreeze, breaking condenser coils and decreasing efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your AC if a severe storm is approaching in Buellton. Hail can seriously damage your system’s coils, altering efficiency.
