Arizona to Idaho: journeyman HVAC technician license reciprocity

Idaho issues a statewide HVAC Journeyman certificate of competency through the Heating, Ventilation and Air Conditioning Board at the Division of Occupational and Professional Licenses (DOPL); a journeyman works in the employ and under the direction of a licensed HVAC contractor. A new applicant pays a $35 application fee and qualifies either by completing 576 hours of instruction at a board-approved apprenticeship program plus 8,000 hours of supervised installation work while registered as an Idaho apprentice, or by documenting 16,000 hours of supervised HVAC installation work, and in both cases must pass the PSI-administered journeyman exam ($75) within a year of applying; the license costs $150 and renews for $75 every three years. DOPL also issues Specialty Journeyman and Limited Heating Specialty Journeyman certificates for hearth appliances, oil furnaces and gas piping. The HVAC board's FAQ states that Idaho has no reciprocal licensing agreement for HVAC. An out-of-state journeyman can instead use Idaho's universal licensure statute (Idaho Code 67-9409), under which the board must license a person holding a current, unrestricted license elsewhere who demonstrates competency, but may still require the Idaho exam; the HVAC application form itself offers no endorsement box, so applicants should contact DOPL before filing. EPA Section 608 certification is required nationwide to handle refrigerants.

Arizona has no state journeyman HVAC license; the Registrar of Contractors licenses only air conditioning and refrigeration contractors (C-39, R-39 and CR-39), and individual technicians work under a licensed contractor without a personal state license. The one large jurisdiction that does license individuals is Phoenix, whose building code requires permitted mechanical work to be done by a City of Phoenix Mechanical Journeyman or a registered apprentice: the journeyman card requires four years of documented experience and passing a $100 mechanical exam based on the 2024 International Mechanical Code, costs $50 for three years, and is not required of an ROC-licensed contractor's qualifying party. Other Arizona cities were not verified for this entry, and the Registrar's pages describe no journeyman credential. An out-of-state journeyman HVAC license has no state-level recognition; Phoenix publishes no reciprocity and requires its own exam, while outside Phoenix a journeyman simply works for a licensed contractor. Federal EPA Section 608 certification is required to handle refrigerants.
