Common causes of AC screeching and how to identify them
Understanding what is causing that screeching sound helps you make the right call. Here is how to diagnose the problem before the technician arrives.
Blower motor belt issues
The blower motor belt connects your indoor fan to the motor. When it gets loose worn or misaligned it creates a high-pitched squeal that gets louder as the system runs. You will hear this noise coming from your air handler inside the house.. Read more about Replacing a dead condenser fan motor in the middle of an Austin heatwave.
Common signs of belt problems include visible wear fraying or glazing on the belt surface. The screeching often starts when you first turn on the AC and may go away after a few minutes as the belt warms up.
Condenser fan motor bearings
The outdoor condenser unit has a fan motor with bearings that wear out over time. When these bearings fail they create a metal-on-metal screeching sound that gets progressively louder. This is often described as a grinding squeal that varies with fan speed.
You will hear this noise coming from the outdoor unit when the AC is running. If you place your hand near the unit you might feel excessive vibration along with the sound.
Compressor high-pressure problems
The compressor is the heart of your AC system. When refrigerant pressure gets too high or internal components fail the compressor can make a loud screeching or screaming noise. This is the most serious of the three problems.
High-pressure screeching often comes with other symptoms like the system shutting off unexpectedly or warm air blowing from vents. The noise may be accompanied by a burning smell or visible smoke from the outdoor unit.
