Montana to Georgia: master HVAC technician license reciprocity

Georgia has no 'master HVAC' license; its highest person-held HVAC credential is the statewide Conditioned Air Contractor license issued by the Construction Industry Licensing Board's Division of Conditioned Air Contractors to an individual who documents experience and passes the PSI-administered exam with a score of at least 70. It comes in two classes: Class I (Restricted) covers systems up to 175,000 BTU of heating and 60,000 BTU of cooling, and Class II (Non-Restricted) is unrestricted, so Class II is the master-level equivalent used here. A Class II applicant needs five years of experience under Rule 121-3-.04 (two years of installation as a lead mechanic with at least one commercial year, one year as a service technician or supervisor, two years of commercial supervisory experience), EPA Section 608 certification of Type II or higher, a Board-approved heat loss and gain and duct design course (Manuals J&D) plus Manuals N&Q or Carrier Design 1-3, three notarized references from licensed professionals, and a local law-enforcement background check; the exam application fee is $110 through the GOALS portal, and the PSI exam fee is paid to the vendor. The licensee then serves as the qualifying licensee for a registered conditioned air company. The Board's FAQ states that 'Reciprocity with other states is not offered at this time' and its online guide has no reciprocity application type; the Board's 2022 paper reciprocity form, which is no longer accepted, named Louisiana as the sole reciprocal state and recorded that South Carolina and Texas reciprocity stopped on April 15, 2022 pending renegotiation. An out-of-state HVAC contractor therefore applies by examination, with experience earned elsewhere documented on the experience record. Licenses renew by November 30 of odd-numbered years with 4 hours of continuing education per year; applications are generally processed within 20 business days.

Montana has no master HVAC, master mechanical, refrigeration or HVAC contractor license; MCA Title 37 chapter 70 (Heating, Ventilation, Air Conditioning) is repealed and the Department of Labor & Industry runs no HVAC program. The nearest state credential is the construction contractor license that every contractor with employees must hold from January 1, 2026 under MCA Title 37 chapter 45 (formerly the $70 construction contractor registration under MCA 39-9): it is issued to the business on proof of workers' compensation compliance with no examination, experience or trade qualification, and a sole operator with no employees instead obtains a $125 Independent Contractor Exemption Certificate, for which 'a test is not required'. Licensed electricians and plumbers are exempt from that chapter, which is why Montana's larger cities license those two trades by their state cards but treat HVAC firms as ordinary contractors: Missoula issues a contractor business license (expires February 28) on $300,000 liability insurance, background checks and state registration, with a $3,000 bond only for gas fitting; Great Falls issues a 'Mechanical' contractor license type for $45 a year on proof of state registration or ICEC, $1,000,000 liability insurance and, for gas fitting, a city-licensed gas fitter of record; Billings and Bozeman require only a city business license ($75 in Bozeman). Boiler operation is separately licensed by the state under MCA 50-74 (six engineer classes, exam-based, no reciprocity provision), and mechanical permits under the state-adopted International Mechanical and Fuel Gas Codes are open to any permit applicant. A master HVAC or HVAC contractor license from another state therefore transfers to nothing in Montana; the holder who wants to run an HVAC business applies for the state construction contractor license (or ICEC), a city business/contractor license where required, and keeps federal EPA Section 608 certification for refrigerant work.
