Your air conditioner may be making a noise due to damaged ducts, a clogged air filter, fan problems, coil damage, loose parts, faulty motor bearings and belts and even electrical issues. Some noises your air conditioner may make include:
A squeaking, squealing or screeching noise -  can be due to an issue with the compressor, fan motor, bearings or damaged blower belts.
A loud buzzing noise - is usually due to an electrical problem.
A clicking sound - can mean your system relays or contractors are failing.
A humming or rattling fan motor noise - can indicate that your AC unit needs to be cleaned, has a worn-out part or has bent or shifted blades.
A banging, whining or whistling noise - can signal poor airflow problems related to leaky air ducts or a clogged air filter.
A hissing noise - is usually due to a refrigerant leak.
Shaking and rattling noise - can be caused by loose air conditioner parts related to air movement.
Constant running noise -  can be due to bent outdoor coil fins.
