Do I Need to Cover My Air Conditioner?

October 18, 2019

With cold weather approaching in New Castle, you may be thinking 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 engineered to withstand severe weather, including extreme temperatures and relentless precipitation.

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

While putting on an air conditioner cover is an individual choice, there are two times of year that are great for using a cover for an extended period of time—fall and summer.  

That’s because yard debris during those seasons—grass clippings, twigs and leaves—can pile up and block your system’s airflow. Diminished airflow means your air conditioning unit works longer and may use more electricity to cool your home.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Central Heating & Plumbing heating and cooling technicians can help. We’ll clean and lubricate your system, and inspect critical parts. This often allows us to identify trouble before they begin.

How to Choose an Air Conditioner Cover

If you decide you want to cover your air conditioner, here are a few ideas on choosing the right cover. 

Avoid Full Covers

To keep air moving, a protective air conditioner cover should only encompass the top of your system and several inches on the side.

Total AC covers can trap condensation inside your unit, potentially eating away at metal parts. It could also make your system a cozy area for vermin, which could chew wires.

Plastic or vinyl covers stop air, which could cause water to build up inside your air conditioner. The best type of fabric is one that’s breathable, 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 blizzard is approaching. Snow and ice that build up 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 system if a bad storm is imminent in New Castle. Hail can severely damage your system’s coils, affecting efficiency.
