In this Motor Age Tech Tip, Meg Richards breaks down everything technicians need to know about servicing vehicles equipped with R-1234yf refrigerant. Although automotive air conditioning systems using this refrigerant have been around for over a decade, many shops still haven’t invested in the proper tools or training to handle them. Richards explains how R-134a and R-1234yf systems differ — from the fittings and oils used, to the additional safety protocols required when working with this mildly flammable refrigerant. She also highlights why technicians should update their 609 certification J2845 to ensure compliance with manufacturer requirements and to better understand safe refrigerant safety and handling practices. 

Learn how the A/C recovery machine used for R-1234yf differs from older R-134a units, including built-in leak detection, identification testing and pre-service safety checks. Richards emphasizes the importance of preventing cross-contamination between refrigerants and following proper disposal procedures for empty canisters.
