Symptoms of a bad AC compressor include:

1.Lack of cooling: If the air conditioning system is not cooling the car's interior, it could be a sign of a faulty compressor. A worn-out or damaged compressor may have difficulty regulating the refrigerant flow necessary for effective cooling.

2.Warm air blowing: When the AC compressor is not working properly, hot air may be blown from the vents instead of cool air. This is a clear indication that the compressor needs to be repaired or replaced.

3.Weak or no airflow: Another symptom of a bad compressor is weak or no airflow from the AC vents. This could be due to a malfunctioning compressor not being able to generate sufficient air pressure.

4.Unusual noises: A loud clattering or rattling noise coming from the air conditioner when it's turned on is indicative of a problem with the compressor. This noise can occur when one or more components of the compressor assembly are broken or damaged.

5. Fluid leakage: Leaking fluid from the AC compressor is a clear sign of a malfunction. The compressor has bearings that prevent fluid leakage, but if these bearings become worn out or damaged, fluid can start to leak. Refrigerant leakage can cause the AC system to stop working and may also pose health risks. If any of these symptoms are experienced, it is recommended to have the AC compressor inspected and repaired by a qualified technician.

Working Principle

The AC compressor is a crucial component of the air conditioning system in your vehicle. It works by compressing the refrigerant vapor, which allows it to circulate and release cold air. The AC compressor is typically attached to the front of the engine using a bracket. It is powered by a belt that drives the compressor's pulley. When you turn on the AC, the AC compressor clutch engages, activating the compressor. This allows the compressor to compress the refrigerant vapor and convert it into a high-pressure gas. When the AC is not in use, the compressor pulley free spins, meaning it does not engage with the compressor. This can result in better gas mileage since the engine does not have to power the compressor. If either the compressor or the clutch fails, you may hear strange noises such as squealing or grinding coming from under the hood when you try to use the AC. This indicates a potential issue that should be addressed to ensure proper functioning of the air conditioning system.

Car AC Compressor working principle

The AC compressor is an essential component of the vehicle's air conditioning system. When you turn on the AC, the compressor begins the process of circulating refrigerant and cooling the air. The compressor works by compressing gaseous refrigerant, which increases its pressure and temperature. This high-pressure gas is then sent to the condenser, where it is cooled and condensed into a high-pressure liquid. The liquid refrigerant then flows through the dryer, which removes any impurities and moisture. Next, the refrigerant passes through the expansion valve, which reduces its pressure and temperature. This low-pressure, low-temperature refrigerant then enters the evaporator, where it absorbs heat from the surrounding air. The now-cooled air is then blown into the vehicle's cabin by the air conditioning system. Without a functioning AC compressor, the entire process of cooling the air cannot happen. If the compressor is damaged or faulty, the AC system will not be able to provide cool air to the cabin. This can result in discomfort during hot weather and decrease the effectiveness of defrosting the windshield. If you suspect an issue with your AC compressor, it is important to have it inspected and repaired by a qualified technician to ensure optimal performance of your vehicle's air conditioning system.
