Changes in the HVAC Industry
Chiller manufacturers are facing a Jan. 1, 2024, implementation date to phase out the use of hydrofluorocarbons (HFCs) R-134a, R-410A, and R-407C in new liquid chillers, despite Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI’s) efforts to change the proposed effective date to Jan. 1, 2025.
Starting in 2024, the three HFC refrigerants will be deemed “unacceptable” in new liquid chillers under the U.S. Environmental Protection Agency’s (EPA’s) Significant New Alternatives Policy (SNAP) program.
AHRI and the National Resources Defense Council (NRDC) requested the EPA consider the 2025 effective date to ensure the safety of alternatives, the continued improvement of system efficiency, reasonable product development timelines, and the avoidance of market migration. The EPA, however, declined to extend the date.
