With cold weather approaching in Houston, 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 strong piece of equipment. It’s engineered to resist inclement weather, including extreme temperatures and torrential precipitation.

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

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

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can build up and obstruct your system’s airflow. Decreased airflow means your air conditioning unit works harder and may use more energy to cool your house.

Looking for other ways to make your air conditioner run efficiently? Regular AC maintenance from Air Current AC & Heat heating and cooling technicians can help. We’ll clean and lubricate your unit, and examine critical components. This often allows us to spot issues before they begin.

How to Find Your Air Conditioner Cover

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

Avoid Full Covers

To keep air flowing, 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 equipment, potentially corroding metal parts. It could also make your air conditioner a welcoming place for rodents, which could eat through wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers block air, which could cause moisture 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 snowstorm is on the way. 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 expect a hailstorm, you can temporarily cover your system if a bad storm is approaching in Houston. Hail can seriously damage your system’s fins, altering efficiency.
