Acoustic Diagnostics
What Do These Aircon Sounds Mean?
High-Pitched Squealing
Usually indicates a dry or damaged fan motor bearing or loose fan belt slipping against the motor pulley.
Loud Vibrating & Rumbling
Caused by deteriorated rubber mounting pads under heavy outdoor condenser units or loose internal brackets.
Hissing or Bubbling
Often points to active refrigerant leaks in copper joints or a faulty thermal expansion valve restricting refrigerant flow.
