Preparing for the Cabin Cooling Transition: R-134a to R-1234yf


R-1234yf refrigerants for mobile air-conditioning systems have been widely used in passenger vehicles for several years, but they are just now gaining traction in medium and heavy-duty commercial vehicles. Environmental policies are driving the shift to R-1234yf, which has a Global Warming Potential (GWP) of <1 compared to R-134a’s GWP of 1,300. This 30-minute Webinar reviews the rationale for refrigerant transition, key regulatory drivers, and differences in the materials.

Topics include:

  • Why heavy-duty cabin-cooling refrigerants are transitioning to YF
  • The current regulatory landscape (Light Duty YF, AIM Act, SNAP for Off-Road Heavy Duty)
  • The difference between R-1234YF and R-134a (Flammability, Performance, GWP)

An audience Q&A follows the technical presentations.
