Tennessee 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.

Tennessee does not issue a master HVAC license. The state-level HVAC credential is a contractor license with the CMC (full mechanical: plumbing and HVAC) or CMC-C (HVAC/refrigeration) classification from the Board for Licensing Contractors, which is issued to a business that names a qualifying agent and is required for any project of $25,000 or more. The qualifying agent passes the Tennessee Business & Law exam and the CMC or CMC-C trade exam (Prov from July 1, 2026; CMC candidates need Board pre-approval, $50), and the business files a reviewed or audited financial statement (or, from July 1, 2026, a surety bond of at least half the requested limit) that sets its monetary limit, proves general liability and workers' compensation insurance, and pays $250 ($200 biennial renewal). The Board's trade-exam-waiver agreements let a contractor licensed in Alabama (HVAC), Louisiana (mechanical), Mississippi (mechanical), Ohio (HVAC), South Carolina (HVAC) or West Virginia (mechanical) skip the trade exam but not the Business & Law exam or any other requirement; North Carolina's and NASCLA's waivers do not cover HVAC. Master-level licenses issued to individuals exist only locally: Nashville's Master Mechanical (six years) and HVAC&R (four years) certificates, Memphis/Shelby County's First-Class and Third-Class Mechanical Contractor licenses, and Chattanooga's Master Mechanical Contractor license. A master HVAC license from another state has no state-level recognition in Tennessee; its holder either registers a business for the CMC-C license or applies for the local master card where they will work. EPA Section 608 certification is required federally to handle refrigerants.
