Do I Need to Cover My Air Conditioner?

October 18, 2019

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

Your AC unit is a tough piece of equipment. It’s engineered to resist inclement weather, including extreme temperatures and heavy precipitation.

Sometimes covers cause more problems, because they can trap moisture. Too much wetness inside your system can cause internal pieces to rust or get moldy.

While putting on an air conditioner cover is your own choice, there are two seasons that are good to use 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 pile up and block your system’s airflow. Reduced airflow means your air conditioning unit works harder and may use more energy to cool your residence.

Wanting other ways to make your air conditioner run efficiently? Routine AC maintenance from Controlled Comfort HVAC Inc heating and cooling experts can help. We’ll clean and lubricate your equipment, and take a close look at essential components. This often allows us to identify trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are several suggestions on picking the ideal cover. 

Avoid Full Covers

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

Complete AC covers can trap condensation inside your system, potentially eating away at metal parts. It could also make your air conditioner a cozy home 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 collect inside your system can melt and refreeze, breaking condenser coils and reducing efficiency.
