Banging

If you hear a loud banging noise from your outdoor unit, the problem is probably with the compressor. Ac compressor is responsible for circulating refrigerant.

Buzzing noise can be heard from both the indoor and outdoor units of your air conditioner. Buzzing sound is a tell-tale sign that indicates that you have an electrical issue. Common electrical AC problems include loose wiring, failing motor, malfunctioning compressor, arcing, and broken capacitor.

Hissing

Normally, a hissing sound indicates a refrigerant leak. However, it could be a sign of a duck leak, an air filter that doesn’t fit correctly in its slot, and a bad expansion valve. During the operation, the refrigerant runs in a closed loop within the cooling unit. But over time, the thin copper lines and coils that carry refrigerant can form leaks and cause the refrigerant to leak.

Squealing

Loud squealing and screeching sounds are caused by a faulty blower motor, a bad compressor, and a bad outdoor fan motor. If the sound is coming from an outdoor unit, then a faulty fan motor and a bad compressor are the major causes.
