Let’s review some of the most common noises with their corresponding causes:

  • Hissing. Depending on where it is, hissing often indicates a very small leak. In general, the sound of hissing requires pressure and two common places that may develop hissing leaks are your refrigerant coils and the ductwork. Your outdoor compressor unit pressurizes the refrigerant and circulates it through the expansion valve, evaporator coils, and condenser coils. The coils can often be intricate and, while often well protected, they are subject to the same wear and tear as other parts of the system. Ducts are often subject to physical damage, from other nearby construction projects, or by loose connections, which can lead to twisting and crimping.
  • Buzzing. Excessive buzzing is often the result of an electrical problem, perhaps from a circuit overload, or damaged wiring. If you think your outdoor or indoor unit is buzzing, this can be hazardous and dangerous.
  • Squealing. The air handler that blows cool air into your duct system relies on the operation of your blower motor, which has a fan belt. This belt connects to the fan blades, and when it becomes worn or damaged, it can begin to squeal, not unlike the fan belt that operates the radiator in your car.

Recognizing that there is something wrong with your air conditioning system is the first step to repair. The next step is calling your local technician. For comprehensive air conditioning repair in Washington, DC, call Service Doctors today!
