Dealing with a Noisy Air Conditioner

Common Air Conditioner Noises
The most common AC noises along with their likely causes include:
Excessive buzzing is often the result of an electrical problem—usually derived from a circuit overload or damaged wiring. If your outdoor or indoor unit is buzzing, call John Nugent & Sons so a professional can inspect your AC system and prescribe an appropriate solution.
Depending on where exactly they’re coming from, hissing sounds often indicate that the unit is leaking. Two common places that may develop leaks are the unit’s refrigerant coils and ductwork. The AC system’s 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, which can lead to twisting and crimping.
The air handler that blows air into your duct system relies on the operation of your blower motor, which has a fan belt. The belt connects to the fan blades—and when it becomes worn or damaged, it can begin to squeal.
Recognizing that there is something wrong with your air conditioning system is the first step to correcting the problem. The next step is calling your dependable HVAC technician! Contact us today for AC services in the Northern VA area.
