With cold weather approaching in New Castle, you may be questioning when you should cover your outdoor air conditioner. Of if you need to cover it at all.

Your AC unit is a strong piece of equipment. It’s engineered to resist bad weather, including intense temperatures and torrential precipitation.

Sometimes covers do more harm than good because they can trap condensation. Too much wetness inside your system can cause internal parts to rust or get moldy.

While installing an air conditioner cover is a personal choice, there are two seasons that are great for using a cover for a long 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 electricity to cool your house.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Central Heating & Plumbing heating and cooling experts can help. We’ll clean and lubricate your unit, and take a close look at critical components. This often allows us to identify problems before they begin.

How to Find Your Air Conditioner Cover

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

Avoid Full Covers

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

Complete AC covers can trap moisture inside your unit, potentially rusting metal parts. It could also make your system a cozy place for rodents, which could sever 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 material 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 heavy snow is coming. Snow and ice that accumulate inside your system can melt and refreeze, breaking condenser coils and reducing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your air conditioner if a severe storm is imminent in New Castle. Hail can seriously damage your system’s fins, affecting efficiency.
