With cold weather approaching in Long Island, 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 sturdy piece of equipment. It’s created to resist inclement weather, including excessive temperatures and relentless precipitation.

Sometimes covers do more harm than good because they can trap moisture. Additional wetness inside your unit can cause internal components to rust or become moldy.

While putting on an air conditioner cover is a personal choice, there are two seasons that are good to use 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 accumulate and block your system’s airflow. Reduced airflow means your air conditioning unit works longer and may use more power to cool your house.

Seeking other ways to make your air conditioner run efficiently? Regular AC maintenance from Airmax Long Island heating and cooling technicians can help. We’ll clean and lubricate your equipment, and examine essential parts. This often allows us to identify trouble before they begin.

Find the Right Air Conditioner Cover

If you come to the conclusion you want to cover your air conditioner, here are several ideas on picking the right cover.

Avoid Full Covers

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

Full AC covers can trap condensation inside your unit, potentially eating away at metal parts. It could also make your air conditioner a welcoming area for vermin, which could chew wires.

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 build up inside your air conditioner can melt and refreeze, damaging condenser coils and decreasing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your system if a strong storm is approaching in Long Island. Hail can severely damage your system’s exterior, altering efficiency.
