Everything including humans requires regular maintenance after a stipulated span of time. Then why leave the car AC? The air conditioning unit is one of the best features and one of the topmost priority of what you may look while buying a new car. After a few months or maybe a year, you may have felt that the car AC is not as effective as it used to be. You may even have experienced slight suffocation when the car AC is running. This is when the time for getting your car AC serviced has arrived. But what happens if you keep running the AC even after these problems? This is what we’ll be dwelling on in this article. Let’s get started.

Testing:

1. Vacuum testing: Connect the vacuum pump to the low-pressure side of the refrigerant system using a manifold gauge set. Evacuate the system by running the vacuum pump for the recommended amount of time specified by the manufacturer. Monitor the gauge readings to ensure that the system holds a vacuum.

2. Leak testing: Once the vacuum is achieved, close the valves on the manifold gauge set and turn off the vacuum pump. Allow the system to sit for a period of time and monitor the gauge readings. If the gauge readings remain stable, it indicates that the system is leak-free. Any significant drop in gauge readings would suggest a refrigerant leak and require further investigation.

3. Operational testing: With the vacuum still intact, proceed to recharge the system with the appropriate amount of refrigerant. Start the engine and turn on the air conditioning. Monitor the compressor operation, including the clutch engagement and refrigerant pressure on the gauge set. Ensure that the compressor operates smoothly and provides the desired cooling effect.

4. Performance testing: Measure the air temperature at the vents using a thermometer. It should be significantly lower than the ambient temperature. If the cooling effect is not satisfactory, it may indicate an issue with the compressor or other components that require further diagnosis.

In conclusion, the proper installation and regular testing of car air conditioning compressors are crucial for maintaining optimal performance. By following the steps outlined above, you can ensure a successful installation and reliable operation of the compressor.
