R-454B refrigerant 2025: EPA SNAP Rules & Michigan Guide
The EPA is phasing out R-410A for new HVAC systems starting in 2025, and R-454B refrigerant 2025 is the path forward. This guide covers the R-410A phase-out date, what the EPA SNAP refrigerant rules mean, why Puron Advance matters, and how to plan a compliant heat pump installation in Michigan.
EPA SNAP Refrigerant Rules & the R‑410A Phase‑Out Date
Starting in 2025, the EPA’s Significant New Alternatives Policy (SNAP) program limits which refrigerants can be used in new HVAC equipment. While existing R‑410A systems can still be serviced, new systems are moving to R-454B refrigerant 2025 and R‑32 to reduce environmental impact without sacrificing comfort.
Quick takeaway: If you’re replacing equipment after the R‑410A phase‑out date, quote R-454B refrigerant 2025 for most ducted homes.

Why Choose R‑454B (Puron Advance)
- ~78% lower GWP vs R‑410A with similar operating pressures
- Broad OEM availability for 2025+ models
- Efficient, quiet performance in modern heat pumps and A/C
- Best general‑purpose upgrade for Michigan homes
Where R‑32 Fits
R‑32 is excellent for ductless mini‑splits and compact applications. It’s efficient and widely used, but its A2L classification means it’s best in smaller, factory‑charged systems.
