Carrier is redeveloping its portfolio of HVAC systems whit Puron Advance

Carrier is continuing to lead in sustainability efforts by phasing in the lower global warming potential (GWP) refrigerant R-454B, commercially known as Puron Advance, to its residential systems complete with new mitigation and reclamation components. Additionally, Carrier’s industry-leading training programs recently opened for enrollment as distributors and dealers ramp up for the changeover in products, navigating tough kitchen table conversations, and phasing-out inventory. 

“Our customers, employees and planet were top of mind when we started collaborating on what changes needed to be made to not just address the refrigerant phasedown in 2025, but to provide the best solution for residential ducted, ductless and light commercial applications for years to come,” said Nick Arch, Managing Director of Residential HVAC, Carrier. “We’re confident that Puron Advance is the lower-GWP, non-ozone depleting potential, solution that will help homeowners achieve their sustainability goals now and in the future.”

With a GWP of 466 – a 75% reduction from R-410A – and non-ozone depleting potential, Puron Advance refrigerant was selected as the best solution to minimize environmental impact and provide longevity based on the United Nations Montreal Protocol Kigali Agreement phasedown plan. Carrier worked closely with regulators and research groups to develop standards, codes and regulations that will help ensure the safe use of R-454B.

Additionally, Carrier has systematically rolled out multifaceted training programs through online courses, in-person training at its new technical training center in Indianapolis, advanced launch materials and webinars, reaching over 800 dealers so far. 

Carrier is redeveloping its portfolio of HVAC systems, enhancing from the inside out so units are lighter, technology-enabled, and equipped with new-refrigerant specific components to support with refrigerant transportation, handling, installation, and leak mitigation and reclamation – ahead of regulatory changes. Changes above and beyond regulatory requirements include lighter coils such as Vertex Technology, enhancements to communicating capabilities through InteliSense Technology, incorporating Near Field Communication for faster installation and servicing, and refrigerant-specific additions such as new leak sensors, differentiated labeling, and early training.
