NASRC’s new event focuses on CO₂ RCUs — an emerging solution gaining traction in smaller-format applications.

Industry leaders say no new refrigerant transition is imminent, but state mandates and affordability pressures threaten the HVACR industry’s “hopeful calm.”  

As part of the court’s decision, the enforcement discretion pertaining to R-404A and R-507A, which was set to expire on Tuesday, March 31, is extended, and the NYSDEC is barred from enforcing the prohibition pending a decision on HARDI’s request for a preliminary injunction.

Despite regulatory uncertainty, A2L refrigerants are rapidly expanding across HVACR sectors, driven by EPA GWP limits and growing demand for sustainability.

New York’s refrigerant rules may cause supply shortages, raising costs for consumers and businesses, as industry groups push for regulatory alignment with federal standards to avoid disruptions. 

A petition filed on behalf of Choice Refrigerants asks the Supreme Court to reconsider a D.C. Circuit ruling that upheld the EPA’s implementation of the HFC phasedown program. 

CO₂ refrigeration avoids regulatory and environmental risks, while delivering long asset life and lower total cost of ownership. 

The shift to A2L refrigerants may seem daunting, but with proper tools, training, and safety know-how, contractors can handle the change with confidence.
