After extensive testing and evaluation, Carrier has selected R-454B, sold as Opteon XL41 from the Chemours Company, to replace R-410A in ducted residential and light commercial packaged products in North America starting in 2023. 

R-454B enables Carrier to achieve their exacting performance standards while exceeding the anticipated requirements of future regulations. With a GWP of 466, Opteon™ XL41 (R-454B) reduces CO2 emissions by 78 percent and improves energy efficiency when compared to R-410A, and it provides over 30 percent reduction in GWP when compared to R-32, another industry candidate to replace R-410A. Opteon XL41 was specifically developed to achieve the maximum possible reduction in GWP to satisfy long-term regulatory requirements. 

"As the world moves toward more environmentally sustainable solutions, equipment manufacturers are searching for lower GWP options that will meet future regulations and can deliver on performance. Opteon XL41 achieves just that," says Diego Boeri, vice president of Chemours Fluorochemicals. "We are thrilled to work in collaboration with Carrier to bring about transformative change for the air-conditioning industry. Chemours is committed to delivering world-class technology through responsible chemistry that reduces impact on global climate change."

Opteon XL41 (R-454B) is an ASHRAE Class A2L (lower flammability), hydrofluoro-olefin based refrigerant and was chosen by Carrier for its balance of performance, energy use and safety, combined with the longevity and peace of mind it offers customers as a low GWP replacement for R-410A. Carrier will market R-454B as Puron Advance™ across North America.
