On August 14th, nearly 30 Synergy members tuned in for a focused, high-impact webinar on A2L refrigerants led by John and Chris from Chemours. With looming EPA regulations and a major market transition away from R-410A, the goal was simple: get the facts straight and equip contractors with what they need to know now.

Why A2Ls Matter
Due to environmental regulations, R-410A is being phased out in favor of A2L refrigerants like R-32 and R-454B. These new refrigerants offer a much lower global warming potential (GWP) – R-454B comes in under 500 compared to R-410A’s ~2,000—but they’re also classified as “mildly flammable.” That’s led to confusion in the field about safety, compatibility, and servicing.

Key Takeaways from the Webinar:

• Safety + Storage: A2Ls are safe when handled properly. There have been no reported fire events globally. Storage limits have increased dramatically – up to 20,000 pounds without sprinklers.

• Training + Certification: No new certification is required beyond EPA 608, but techs must understand cylinder adapters, leak sensors, and new labeling.

• Service Equipment: Most existing tools will still work, but make sure they’re rated for A2Ls. Vehicles can transport up to 440 pounds without special DOT compliance.

• No Retrofits: R-410A systems cannot be retrofitted to A2Ls. Reclamation of R-410A will be critical after 2029.

• Supply Chain: Supply issues with R-454B are improving as manufacturers ramp up packaging and production. Chemours expects strong availability through 2026.

The Bottom Line
This transition is happening now, and our members are in a prime position to lead the way with clear communication, technician readiness, and a firm grasp of best practices.
