Goods Picture

Here are 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.

General system

Each system may vary slightly per vehicle. For example, some may include an orifice tube whereas others have an expansion valve. This means the system has up to 7 components including:

1.Compressor: compresses cool refrigerant gas into hot refrigerant gas

2.Condenser and fan: converts hot refrigerant gas into a hot liquid at high pressur

3.Receiver Dryer: temporarily stores refrigerant when not needed by the system

4.Expansion (TX) Valve / Orifice Tube: regulates refrigerant flow / creates pressure drop

5.Evaporator: cools air before entering cabin

6.Heater Core: warms air before entering cabin (uses engine coolant rather than refrigerant)

7.Blower Motor: fans hot or cold air into the cabin
