2025 Federal HVAC Mandate

The 2025 Refrigerant HVAC Mandate is a regulation introduced to reduce the environmental impact of refrigerants used in HVAC systems. Starting in 2025, manufacturers and installers must transition to using refrigerants with a lower global warming potential (GWP), such as R-32 and R-454B, instead of older, high-GWP options like R-410A. This mandate is part of broader efforts to comply with the Kigali Amendment to the Montreal Protocol, which aims to phase down hydrofluorocarbon (HFC) use. The change promotes energy efficiency and aligns with sustainability goals, but it may require HVAC professionals and consumers to update equipment and adapt to new installation and maintenance standards.
