riser box(es), provided such connections do not exceed 6 feet (1829 mm) in length.
▪ Provide Detail of Refrigerant Chase. - 2018 IECC Section C103.2Information on construction
documents. - 2018 IBC Section [A]107.2.1Information on construction documents.
▪ See Below State of Arizona adopted policy for Type A2 Refrigerants.
▪ Policy Title: Alternative Refrigerants
Applicable Code Sections: International Mechanical Code Chapter 11
International Residential Code Chapter 14
Purpose: To establish a common set of regulations for the design and installation of cooling systems
utilizing alternative refrigerants as mandated by the United States Environmental Protection Agency
(EPA).
Policy: Cooling systems may be designed and installed in accordance with the currently adopted
International Mechanical Code (or International Residential Code as applicable) or the most current
edition of ANSI/ASHRAE 15 with the companion standard ANSI/ASHRAE 34.
Background: On October 24, 2023, the EPA published a final rule restricting the production and use of hydrofluorocarbon (HFC) refrigerants for residential and light commercial heating ventilation and air
conditioning (HVAC) systems through the Technology Transitions Program. The rule, as originally
issued, placed restrictions on both the manufacture and installation of HVAC products and systems
beginning on January 1, 2025, utilizing HFC refrigerants. Alternative refrigerants that meet these new
requirements are also new to the building and mechanical codes. While the newest building safety
standards address how systems using these new refrigerants must be designed and installed, local
authorities having jurisdiction (AHJ) may not have the new regulations adopted or implemented yet. For
local AHJs to continue using their existing building safety codes, an option is needed for the refrigeration
sections of those codes.
Process: Permit applicants seeking to use alternative refrigerants that are not identified in the adopted
building safety codes shall declare the use of ANSI/ASHRAE 15 with the companion standard
ANSI/ASHRAE 34 for refrigerant system designs on permit application and/or the construction
documents prior to submitting a permit application.
