California to Alaska: master HVAC technician license reciprocity

Alaska has no master HVAC license; its highest person-held HVAC credential is the Mechanical Administrator license issued under AS 08.40.210-08.40.490 by the Division of Corporations, Business and Professional Licensing (CBPL), which is treated here as the master level. It is a supervisory license: a person may not act as a mechanical administrator without it, every registered mechanical contractor must hold or employ one, and the administrator is responsible for all mechanical work done under the contractor's license (AS 08.40.260, 08.40.280; 12 AAC 39.902). The license is issued in categories; the HVAC-related ones are Unlimited HVAC/Sheet Metal (UHVCS), Residential HVAC (RHVC), Unlimited Refrigeration (UR), Heating, Cooling and Process Piping (HCPP) and Mechanical Systems Temperature Control (CNTL), with plumbing categories (UCIP, RPHH) alongside. Qualification is by experience (for example four of the last six years as a journeyman or field superintendent in HVAC and sheet metal work for UHVCS, or two of the last four years as a journeyman for UR and RHVC, where a year means at least 1,500 hours) plus a PSI-administered examination passed at 70% within the prior 12 months, or by credentials for administrators licensed in another state. Fees are $150 to apply plus $200 for the license ($350); the license is biennial, expiring December 31 of odd-numbered years, and renews for $200 with an eight-hour Uniform Mechanical Code workshop per category. The administrator license does not by itself let the holder install fuel gas piping (that needs a DOLWD Plumber Gas certificate) or original control wiring (that needs an Electrical Administrator), and anyone handling refrigerants needs federal EPA Section 608 certification.

California does not issue a master HVAC or master refrigeration license, and the credential that sits above the (non-existent) journeyman level is a CSLB contractor license in classification C-20 Warm-Air Heating, Ventilating and Air-Conditioning or C-38 Refrigeration. That license is issued to a business (sole owner, partnership, corporation or LLC) and qualified by a named individual rather than held by the mechanic personally, so an out-of-state master HVAC license transfers to nothing unless the holder intends to contract; a master who only wants to work for an employer needs no California license at all. To contract, the qualifying individual must document at least four years of journeyman-level or higher experience within the past 10 years, pay the $450 application fee, pass both the CSLB Law and Business exam and the C-20 (or C-38) trade exam through PSI within 18 months, be fingerprinted, post a $25,000 contractor's bond (plus a $25,000 bond of qualifying individual where applicable), carry workers' compensation or file an exemption, and pay the initial license fee of $200 (sole owner) or $350 (non-sole owner) for a two-year license. CSLB's reciprocity program can waive the trade exam for a contractor who has held an active license in good standing for the previous five years in a classification on the Reciprocal Classifications List: for C-20 the mapped classifications are Arizona C-39, C-39R (as printed), K-39, K-79, L-39 and L-79 Air Conditioning and Refrigeration and Nevada C-1f Heating, Cooling and Circulating Air and C-21 Refrigeration and Air Conditioning; for C-38 they are Arizona L-49 Commercial and Industrial Refrigeration and Nevada C-21a Refrigeration. The Louisiana, Mississippi and North Carolina reciprocity entries cover only general building. Even where reciprocity is granted CSLB retains the right to require the trade exam, decides comparability case by case, and always requires the Law and Business exam, bond, fingerprinting and every other licensure requirement. EPA Section 608 certification is a federal prerequisite for handling refrigerants and is not part of the CSLB application.
