Carrier Advances Sustainability, First to Make Lower GWP Refrigerant Heat Pumps Available for Order

Carrier’s latest single-stage heat pump launch marks the first heat pumps available to the field that are R-454B compatible well in advance of the 2025 regulatory shift. R-454B, known commercially as Puron Advance™, is Carrier’s refrigerant of choice for all ducted and ductless residential and light commercial applications. Additionally, Carrier was the first to announce its refrigerant of choice in 2018 and the first to publish AHRI ratings for R-454B equipment. Carrier is a part of Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions.

"Carrier distributors and dealers will lead the industry with our R-454B compatible units available for early training and installation," said Nick Arch, Vice President and General Manager, Residential HVAC Solutions, Carrier. "We continue to stress the importance of preparation and inventory management and are proud to be doing our part as the first manufacturer to get R-454B systems in the field."

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. The recent designation of its Collierville, Tennessee facility as its Center of Excellence for heat pump production further underscores Carrier’s commitment to sustainability.

In addition to heat pumps, Carrier also opened orders for R-454B compatible fan coils and evaporator coils. All available units will begin arriving in warehouses across the country in early April.
