What matters most when comparing refrigerants
GWP (Global Warming Potential) measures a refrigerant's climate impact relative to CO2 over 100 years. R-410A has a GWP of 2,088; its successor R-454B has a GWP of 466 — a 78% reduction. R-32 has a GWP of 675, and R-22 has a GWP of 1,810.
ODP (Ozone Depletion Potential) measures damage to the stratospheric ozone layer. R-22 has an ODP of 0.055 — the primary reason it was banned. All HFCs (R-410A, R-454B, R-32, R-134a, R-404A) have an ODP of zero.
Phase-out status determines how long a refrigerant will be available at stable prices. R-22 is fully phased out (production banned in 2020). R-410A and R-404A are subject to AIM Act phase-down with tightening allowances through 2036. R-454B and R-32 are considered long-term options.
EPA Section 608 leak thresholds apply to all refrigerant systems containing 15 lbs or more (as of January 1, 2026). Commercial refrigeration systems must stay below a 15% annual leak rate; comfort cooling systems below 30%.
