• Refrigerant Lines: These lines transport refrigerant between the indoor and outdoor units. Leaks or restrictions in these lines can cause unusual noises.
• Evaporator Coil (Indoor Unit): This coil absorbs heat from the air inside your home, cooling it down.
• Condenser Coil (Outdoor Unit): This coil releases heat from the refrigerant to the outside air.
• Ductwork (Indoor Unit): The network of ducts distributes cooled air throughout your home. Issues within the ductwork can contribute to noise.
