The #1 Way You May Accidentally Kill Your Air Conditioner This Summer


Every summer we get calls from Atlanta homeowners who have accidentally killed their air conditioners.

The cause of death? Suffocation

Air conditioners, like people, can suffocate when you restrict the airflow in or out of them. So how do homeowners suffocate their air conditioners? Well, there are 3 common ways.

Covering your air conditioner’s outdoor unit

Why this is bad: The outside unit’s job is to dump heat from your home to the outside air. And to do this efficiently, it needs a lot of air. A decorative cover (like the one below) restricts airflow to the air conditioner and can kill your AC’s compressor.

The compressor is the heart of your air conditioning system. If it dies and isn’t covered by warranty, the repair will be very expensive. In many cases, you’ll be better off replacing the whole outdoor unit.

How to fix it: Remove anything blocking airflow to your outdoor air conditioner unit, including bushes, overhanging tree branches or decorative covers.
