Low riskResidential air conditioning refrigerants transitioning from R-410A (GWP 2088) to R-32 (GWP 675) and R-454B (GWP 466) under the AIM Act (2020) and Kigali Amendment.
What is this product?
Residential air conditioning refrigerants transitioning from R-410A (GWP 2088) to R-32 (GWP 675) and R-454B (GWP 466) under the AIM Act (2020) and Kigali Amendment. R-410A phase-down: 40% reduction by 2024, 80% by 2029. R-32 is mildly flammable (A2L classification) — requires updated installation practices but is not a consumer safety concern in properly installed systems. Refrigerant leaks contribute to both ozone depletion (legacy R-22) and climate forcing (current HFCs).
