• Buzzing: Buzzing can be caused by several issues, including loose parts, electrical problems, or a malfunctioning fan motor.
• Squealing: A squealing noise often indicates a problem with the fan motor, such as worn-out bearings or a slipping belt.
• Rattling: Rattling sounds typically come from loose parts inside the unit, such as a fan blade that’s hitting something or debris caught in the unit.
• Banging/Clanging: Loud banging or clanging noises are often a sign of serious mechanical issues, such as a broken compressor or a loose component that’s hitting other parts.
• Whining: A whining sound can be a sign of compressor issues or motor problems.
• Gurgling: Gurgling sounds may indicate refrigerant leaks or problems with the drain line.
