With cold weather approaching in Warrenton, 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 sturdy piece of equipment. It’s designed to resist bad weather, including intense temperatures and relentless precipitation.

Sometimes covers cause more problems because they can trap moisture. Additional wetness inside your unit can cause internal components to rust or turn moldy.

While installing an air conditioner cover is a personal 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 accumulate and obstruct your system’s airflow. Diminished airflow means your air conditioning unit works more and may use more energy to cool your house.

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

Choosing the Right Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are several suggestions on selecting the best cover.

Avoid Full Covers

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

Complete AC covers can trap condensation inside your system, potentially rusting metal pieces. It could also make your AC a cozy area for animals, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers block air, which could cause moisture to build up inside your air conditioner. The best type of material 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 on the way. Snow and ice that accumulate inside your AC can melt and refreeze, damaging condenser coils and lowering efficiency.

Although it’s not always possible to anticipate a hailstorm, you can temporarily cover your air conditioner if a bad storm is coming in Warrenton. Hail can severely damage your system’s coils, impacting efficiency.
