Air conditioning systems don’t run in silence, and even with
advances in technology to dampen the sounds they make, there is no way to avoid
some noise coming from the compressor and the motors powering the fans and the
blowers. When you have your AC operating—which in Florida is “most of the time”—you’ll
have a background of white noise to which you’ll become accustomed.

But then… some odd sound you don’t expect interrupts your semi-peace and quiet. A grinding, a hissing, a rattling. You might feel tempted to ignore it and just deal with it, sort of like a barking dog in a neighbor’s yard. But those noises are more than distractions. They often indicate something is wrong with the cooling system and you need to call us for AC repair services in West Palm Beach, FL.

A breakdown of some of these noises and what they mean can help
you identify when it’s time to reach out for technician assistance.


These are mechanical noises that are probably coming from the
motors. A shrieking sound is the bearings in the motors wearing down. When the
bearings completely wear down, the motors will take severe damage and burn out.
Moving fast to have professionals replace the bearings can rescue you from a
much more expensive motor replacement. Grinding, however, is usually a sign
that the motors are already burning out and you’ll soon have a non-working air
conditioning system.


This is a sound associated with hard starting, when the motor for the compressor must draw on a larger amount of electricity than normal to overcome the initial resistance. The sound comes from the capacitors, the electrical components responsible for sending voltage to the motor to start it and keep it running. Capacitors are prone to failure before the end of the air conditioning system’s service life and often need replacements. Call to have the capacitors looked at when you hear this clicking sound during start-up.


If you hear this sound coming from the indoor HVAC cabinet,
it may be as simple as a loose latch on the cabinet door. But it can also warn
of more serious problems: loose fan blades, loose parts in a motor, debris
caught inside the blower housing, or the unit becoming unstable on the floor.
If you can’t find a basic issue behind this noise, have our technicians take a
look at it.


No, you probably don’t have a snake inside your air
conditioner. The sound you’re hearing is the escape of high-pressure refrigerant
gas from a hole in the copper refrigerant lines. A small sound, a serious problem.
Refrigerant leaks put the entire air conditioning system in jeopardy because
they will eventually cause the compressor to break down. Solving the problem
requires experts to locate the leaks, seal them, and then replace the lost refrigerant
so the AC is restored to its proper charge. (It’s important it isn’t overcharged,
a common problem with amateur repair people.)
