4 Indications of a Faulty Car AC Compressor:

1. Unusual Sounds From the Running Compressor If you hear strange noises coming from your car's AC unit when the air conditioner is turned on, it may be a sign that the AC compressor is not functioning properly. The compressor is made up of various components and bearings, and if any of them break or seize operation, they can create squealing or grinding noises. These noises are an indication that the AC unit needs repair or replacement.

2.Abnormally High Interior Temperatures No one wants their car's AC to blow hot air, regardless of the season. If your AC is not blowing cold air, it could be a result of a faulty compressor. Checking the compressor is necessary to address the issue of hot air inside the car.

3.Fluid Leaks Another potential symptom of a malfunctioning AC compressor is fluid leakage. The compressor contains bearings that prevent refrigerant or other fluids from leaking. If a bearing becomes worn out, it can cause fluid leakage and ultimately lead to the compressor's malfunction. When looking for signs of AC repair, it is important to check for any leaks in the system.

4.Stuck AC Compressor Clutch The AC compressor clutch is connected to the engine by a pulley, allowing the engine's power to be used by the compressor only when necessary. If the clutch is broken, it will be unable to transfer power from the engine to the compressor, resulting in the compressor's failure to function. Therefore, it is advisable to have the clutch repaired or replaced to ensure proper functioning of the AC compressor.

The role of compressor

The compressor is an essential component of the air conditioning system in a vehicle. Its primary function is to circulate and compress the refrigerant gas, which is responsible for cooling and dehumidifying the air in the cabin.

The process starts with the compressor drawing in low-pressure refrigerant gas from the evaporator and then compressing it into a high-pressure, high-temperature gas.

This compressed gas is then sent to the condenser, where it releases heat and transforms into a high-pressure liquid. After leaving the condenser, the pressurized liquid refrigerant flows through the receiver drier or accumulator, which removes any moisture or debris from the refrigerant. From there, the refrigerant passes through the expansion valve or orifice tube, which regulates the flow of the refrigerant into the evaporator. Inside the evaporator, the high-pressure liquid refrigerant rapidly expands and evaporates, absorbing heat from the air passing over the evaporator's fins.

This cools the air and reduces its humidity. The cooled air is then blown into the cabin through the vents, providing a comfortable and refreshing environment for passengers. Overall, the compressor plays a crucial role in the refrigeration cycle of the air conditioning system, ensuring that the refrigerant is properly circulated, pressurized, and transformed to achieve effective cooling inside the vehicle.
