7. Practical Tips and Tricks for A/C Services

As vehicle technology evolves, air conditioning (A/C) systems also become more sophisticated. Here are some practical tips and tricks for technicians working on A/C services:

7.1. Refrigerant Identification

Always identify the type of refrigerant used in the vehicle’s A/C system before performing any service. Mixing different refrigerants can damage the system and is illegal. Refer to the owner’s manual or check under the hood for the manufacturer’s label.

7.2. Proper Recovery and Recharge Procedures

Follow the manufacturer’s recommended procedures for refrigerant recovery and recharge. Ensure the A/C service equipment is properly calibrated and maintained. According to Chemours, mixing R-134a and R-1234yf is illegal, unsafe, and may compromise systems, performance, equipment, and warranties.

7.3. Leak Detection Techniques

Use advanced leak detection techniques, such as forming gas leak detection, to identify refrigerant leaks quickly and accurately. Texa Forming gas leak detection is an emerging technology that is commonly used with high-end vehicle systems.

7.4. Valve Core Replacement

Replace the valve cores anytime you service an A/C system, especially if the recovered refrigerant charge is less than the OE recommendation. Leaks often occur through the valve cores.

7.5. Vacuum and Moisture Removal

Ensure the A/C system is properly evacuated to remove moisture and non-condensable gases. Insufficient vacuum can lead to acid formation and premature compressor failure. Vacuum readings should reach a minimum of 29.25 inches of mercury to ensure moisture boils and is removed from the system.

7.6. System Oil Management

Maintain the correct oil level in the A/C system. Excessive oil can reduce cooling performance, while insufficient oil can lead to compressor damage.

7.7. Filter Replacement

Replace the desiccant filter/receiver drier regularly to remove moisture and contaminants from the refrigerant. Doing so will aid in preventing premature compressor failure.

8. Future Trends in Automotive Diagnostics
