ASE to Hold Webinar on R‑1234yf Refrigerant Retrofits Thursday

The National Institute for Automotive Service Excellence (ASE) is hosting the free webinar “R‑1234yf Refrigerant Retrofits for R-134a Automotive A/C Systems” on Thursday, May 7 at 4 p.m. ET. 

In 2026, air conditioning service technicians will have an additional servicing option for R-134a automotive A/C systems. The Environmental Protection Agency’s (EPA) newest rulemaking, SNAP Rule #27, will allow the use of R-1234yf as a retrofit refrigerant. 

Kerry Gray from Chemours and MaryJo VandenBrink from Solstice will outline a new chapter coming in A/C service. Topics covered will include an overview of EPA SNAP Rule #27 and details involved with the retrofitting process, including specifics about new service fittings and labeling requirements.
