Arlington, Va. – The Air-Conditioning, Heating, and Refrigeration Institute (AHRI) today announced the release of a new interactive map of the United States listing state and local building codes and legislation passed to allow equipment using A2L refrigerants and a video series about the industry's transition to low-global warming potential refrigerants.

AHRI's interactive map is a valuable tool for original equipment manufacturers, authorities having jurisdiction, building inspectors, fire marshals, code or other officials, and lawmakers seeking information about applicable air conditioning, refrigeration, and warehousing codes, legislation, and standards currently referenced.

"As we learn more about US states' and territories' plans regarding the transition to A2Ls, it is important to have a trusted source of accurate, up-to-date information on building codes and legislation available to stakeholders. This is the benefit of the interactive map, which will be revised as codes and laws are updated," said Tom Deary, AHRI Director of Codes. Access the interactive map webpage here.

The A2L video series, developed by AHRI in partnership with the International Code Council (ICC) and the Plumbing-Heating-Cooling Contractors National Association (PHCC), provides brief explanations of some aspects of the refrigerant transition that are critical for contractors, distributors, technicians, fire and safety professionals, and other interested parties to know. Topics include An Overview of A2L Refrigerants, The A2L Refrigerant Transition Timeline for 2024 and 2025, Changes Made to Future Codes and Standards Addressing A2L Refrigerants, Preparing for the Transition to A2L Refrigerants: What Building Inspectors, Code Officials, and Contractors Need to Know, Restrictions on A2L Refrigerant Use, The Basics of Handling A2L Refrigerants, and How to Find A2L Refrigerant Training Resources.
