With cold weather approaching in Libertyville, you may be thinking 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 engineered to resist bad weather, including extreme temperatures and relentless precipitation.

Sometimes covers cause more problems because they can trap condensation. Extra wetness inside your unit can cause internal components to rust or become moldy.

While installing an air conditioner cover is an individual choice, there are two periods 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 build up and block your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more energy to cool your residence.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from TopTec heating and cooling technicians can help. We’ll clean and lubricate your equipment, and take a close look at important components. This often allows us to pinpoint issues before they begin.

Choosing the Right Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are a couple tips on selecting the right cover.

Avoid Full Covers

To keep air flowing, a protective air conditioner cover should only enclose the top of your equipment and a couple of inches on the side.

Complete AC covers can trap condensation inside your equipment, potentially rusting metal components. It could also make your AC a welcoming home for vermin, 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 a blizzard is coming. 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 expect a hailstorm, you can temporarily cover your air conditioner if a severe storm is coming in Libertyville. Hail can seriously damage your system’s exterior, impacting efficiency.
