R-454B refrigerant 2025: EPA SNAP Rules & Michigan Guide | Cooley Mechanical

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.

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.
