Causes for a Clicking Air Conditioner

  1. Expansion and Contraction: 

If your ductwork is warm or at room temperature when the cool air starts to flow through it, the fluctuations in temperature in the air conditioning system can cause the various metal components to expand and contract. This expansion and contraction can sometimes result in clicking sounds vary in tempo or speed as the system adjusts to the temperature changes. 

  1. Loose or Damaged Parts: 

Over time, certain parts of the air conditioner, such as fan blades, panels, or fasteners, can become loose or damaged. Loose components may vibrate or rattle, leading to clicking sounds when the system is in operation. Similar to expansion and contraction, this kind of clicking will also present as inconsistent with a varied speed or tempo. 

  1. Electrical Issues: 

Clicking sounds could be caused by electrical problems within the air conditioning system. Faulty wiring, loose connections, or damaged components such as relays or capacitors can generate clicking noises. These clicking noises are often consistent in sound and tempo, and only occur when the unit is turned on. 

  1. Faulty Fan Motor: 

The air conditioner’s fan motor plays a crucial role in circulating the air. If the motor is malfunctioning or has worn-out bearings, it may produce clicking sounds as it struggles to function properly. Faulty fan motor clicks will most often present a consistent sound and tempo, especially over time. 

  1. Defective Compressor: 

The compressor is a vital component responsible for pressurizing the refrigerant in the air conditioner. If the compressor is faulty or damaged, it might produce clicking or clanking noises when it tries to start or shut down. You also will notice no cold air blowing from your air conditioner in this case.
