Tackling a Noisy Air Conditioner

Posted On: June 05, 2013

Do you hear odd noises coming from your AC unit? Noises coming from an air conditioning unit can be due to a variety of reasons—depending on the type of unit. These noises should not be ignored and are almost always a sign that your unit requires professional AC repair service. In some cases, an air conditioning unit is beyond repair by the time it starts producing loud noises. This means you’ll need to consider complete AC replacement.

Homeowners throughout Lenexa, Olathe, Overland Park, and nearby areas in KS depend on their air conditioning systems all summer long to provide high quality cooling performance and energy efficiency. A noisy AC unit should be inspected immediately by a professional Kansas HVAC technician.

Common Air Conditioner Noises

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

Hissing

Depending on where exactly it’s 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.

Buzzing

Excessive buzzing is often the result of an electrical problem—perhaps from a circuit overload or damaged wiring. If your outdoor or indoor unit is buzzing, call Top Notch Heating, Cooling & Plumbing so a professional can inspect your AC unit and offer an appropriate solution.

Squealing

The air handler that blows air into your air 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. If you observe strange, loud noises coming from your unit—you know there’s a major problem. The next step is calling your dependable HVAC technician!
