Do you hear strange noises coming from your AC system? 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. In some cases, an air conditioning unit is beyond repair by the time it starts being noisy. This means you’ll need to consider complete AC replacement.
Homeowners throughout the Valley-Metro area depend on their air conditioning systems all summer long to provide high-quality cooling performance and energy efficiency. A noisy AC should be inspected immediately by a professional HVAC technician.

Most 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 also 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 Cooper Climate Control Heating & Air Conditioning so a professional can inspect your AC system and prescribe 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. The next step is calling your dependable local AC technician! Contact us today for AC services in the Valley-Metro area.
