R-454B Refrigerant 22 lb Cylinder — Low-GWP A2L R-410A Replacement

R-454B is a next-generation, low-GWP A2L refrigerant designed to replace R-410A in new air conditioning and heat pump systems. It delivers comparable performance with dramatically lower global warming potential — a smart, future-ready solution for residential and commercial HVAC.

A2L — mildly flammable. Requires A2L-compatible service equipment and trained technicians. Not for retrofitting existing R-410A systems — designed for new equipment engineered for A2L refrigerants.

Key Benefits

  • Ultra-low GWP (~466): reduces climate impact by nearly 80% vs R-410A (GWP ~2,088).
  • High efficiency, low emissions: similar cooling capacity and energy efficiency to R-410A with improved environmental performance.
  • Mildly flammable (A2L): non-toxic and mildly flammable; safe in properly designed systems.
  • Future-ready: compliant with evolving F-Gas and AIM Act restrictions on high-GWP refrigerants.
