With cold weather on the horizon in Manassas, you may be wondering when you should cover your outdoor air conditioner. Of if you have to cover it at all.

Your AC unit is a strong piece of equipment. It’s created to resist severe weather, including extreme temperatures and relentless precipitation.

Sometimes covers cause more problems because they can trap moisture. Extra wetness inside your equipment can cause internal pieces to rust or become moldy.

While installing an air conditioner cover is an individual choice, there are two times of year that are good to use a cover for a lengthy period of time—fall and summer.

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

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Fire & Ice HVAC heating and cooling professionals can help. We’ll clean and lubricate your unit, and examine essential parts. This often allows us to pinpoint problems before they begin.

Choosing the Right Air Conditioner Cover

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

Avoid Full Covers

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

Total AC covers can trap water inside your system, potentially corroding metal pieces. It could also make your system a cozy place for rodents, which could eat through wires.
