Preparing for R-410A Phase-Down: Guidance for the Seychelles RAC Sector
R-410A, the dominant refrigerant in residential and light commercial air conditioning, has a GWP of 2,088. As HFC consumption caps tighten, availability and pricing of R-410A will be affected.
Alternatives available now
R-32 (GWP 675): drop-in for many split AC systems, widely available from manufacturers. R-290 propane (GWP 3): used in self-contained commercial refrigeration, requires A3-rated equipment. R-454B (GWP 466): emerging replacement for R-410A in ducted systems, requires minor equipment modifications.
Recommendations
When replacing equipment, choose models designed for lower-GWP refrigerants. Ensure technicians servicing new-generation equipment hold current certification. The Ozone Unit can advise on permit requirements for new refrigerant types.
