Do I Need to Cover My Air Conditioner?

With cold weather approaching in Saint Charles, you may be wondering 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 designed to withstand inclement weather, including intense temperatures and torrential precipitation.

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

While putting on 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 pile up and lower your system’s airflow. Decreased airflow means your air conditioning unit works more and may use more energy to cool your home.

Wanting other ways to make your air conditioner run efficiently? Annual AC maintenance from Air Alliance Team heating and cooling professionals can help. We’ll clean and lubricate your equipment, and inspect important pieces. This often allows us to pinpoint trouble before they begin.

How to Choose an Air Conditioner Cover

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

Avoid Full Covers

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

Total AC covers can trap condensation inside your equipment, potentially rusting metal components. It could also make your AC an inviting place for vermin, which could chew wires.

Don’t Use Plastic or Vinyl Covers

Plastic or vinyl covers block air, which could cause condensation to build up inside your air conditioner. The best type of cloth 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 approaching. Snow and ice that build up inside your system can melt and refreeze, damaging 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 coming in Saint Charles. Hail can seriously damage your system’s fins, impacting efficiency.
