Refrigerants, A2Ls and Regulations

Keeping Pace with changing regulations, system design, and safety protocols

HVACR continues to undergo significant changes in regulation. Central to these changes are A2L refrigerants, or refrigerants considered to be mildly flammable, safer and more environmentally friendly alternatives compared to traditional, High GWP options. Governments across the globe move to tighten regulations in an effort to phase out these high-GWP refrigerants, and the HVACR industry consistently faces new challenges and opportunities for system design and safety protocol.

What industry leaders are saying about Refrigerants, A2Ls and Regulations

(Excerpts from the 2026 AHR Expo Trend report)


“2026 will test the industry’s ability to adapt as much as it will reward those who’ve learned from the past two years. The refrigerant shortages of 2025 exposed the cost of weak forecasting and breakdowns in communication across the supply chain, but they also sharpened the industry’s awareness of what coordinated planning requires. The way distributors manage pricing impacts from tariffs will reveal — and strengthen — their value as partners to their customers. It will also be essential that we continue stay the course set by the AIM Act, even as uncertainty surrounding the Technology Transition Rule creates some unease. HARDI remains focused on ensuring distributors have the insight and tools to meet these challenges head-on.”

“Completing the global transition toward next-generation refrigerants remains high on our industry’s priority list. Our continued efforts to expand our global reach – we recently opened our 6th global office, in Singapore – will help policymakers there and in many other parts of the world use our standards and certification programs as paths to achieve sustainability goals. Other pressing issues include continued state efforts to regulate PFAS and plastics and packaging, and expand extended producer responsibility efforts.”

— Steve Yurek, AHRI


“Last year’s concerns for acceptance of new products brought forth by the refrigerant transition were proven to have been overstated. Prompt market acceptance of A2L products has created other supply side concerns for equipment and refrigerant availability, prompting more repair of existing systems than is typical for most contractors.”

— Cindy Sheridan, PHCC

One area that is being closely monitored is the evolving regulatory landscape, particularly concerning refrigerant regulations and energy efficiency standards. Staying compliant with these regulations while maintaining system performance and cost-effectiveness is a significant concern for industry stakeholders. The impact of climate change on HVACR system design and operation, including the need for more resilient and adaptable systems, is also a critical issue on the radar. (Source: ASHB)
