Requirements at a glance

Who must be licensed - Alaska licenses the mechanical CONTRACTOR and the individual who qualifies it: Alaska runs HVAC licensing through two linked state credentials, neither of which is an HVAC technician license. First, the contracting business must hold a certificate of registration as a contractor: 'A person may not submit a bid or work as a contractor until that person has been issued a certificate of registration as a contractor by the department' (AS 08.18.011(a)), and a business doing heating, air conditioning, ventilating, sheet metal, plumbing, or pipe fitting work registers in the MECHANICAL classification (AS 08.18.171(13)); the statute defines 'specialty contractor' as a contractor 'other than a mechanical contractor' (AS 08.18.171(17)), so HVAC does not fall in the specialty class. Second, that registration cannot issue unless the business 'is, or employs, a person currently licensed as a mechanical administrator under AS 08.40' (AS 08.18.028(a)), and 'a person may not act as a mechanical administrator without a license unless the person is covered by an exclusion under AS 08.40.390' (AS 08.40.260(a)). A mechanical administrator is the person responsible for installing or modifying mechanical piping and systems, devices, fixtures, equipment, or other mechanical materials subject to the Uniform Plumbing Code, Uniform Swimming Pool, Spa, and Hot Tub Code, Uniform Solar Energy Code, and Uniform Mechanical Code, or for certifying that such an installation or modification complies with the applicable codes (AS 08.40.490(3)). An HVAC installer or service technician working for a registered mechanical contractor is not required to hold a mechanical administrator license in order to do the hands-on work - the credential sits with the business and its administrator. One important exception runs the other way: fuel and gas piping is plumbing work in Alaska, and a plumbing certificate of fitness applies to the individual doing it (see the fuel-gas requirement below).
Mechanical administrator categories - you may only work in the category you hold: 'A person licensed under AS 08.40.210 - 08.40.490 may perform work only in a category for which the person is licensed' (AS 08.40.260(b)). The department publishes these mechanical administrator categories on its Mechanical Administrators program page and on its application forms: Heating, Cooling and Process Piping (HCPP); Unlimited HVAC/Sheet Metal (UHVCS); Residential HVAC (RHVC); Unlimited Refrigeration (UR); Mechanical Systems Temperature Control (CNTL); Unlimited Commercial and Industrial Plumbing (UCIP); and Residential Plumbing and Hydronic Heating (RPHH). For HVAC work the operative categories are UHVCS (the broad HVAC/sheet metal license), RHVC (single-family and duplex dwellings not exceeding three stories, warm air heating up to 240,000 B.T.U./hour input, and integral fuel gas or fuel oil piping), UR (the refrigerant cycle, unlimited as to capacity or refrigerant type), HCPP (hydronic and process piping, boilers), and CNTL (temperature controls). A licensee may add a category by filing the application and passing that category's examination (12 AAC 39.025), paying another $150.00 application fee (form 08-4905).
Examination - PSI Exams, 70 percent, valid one year, three attempts per 12 months: A complete application for a mechanical administrator license by examination requires 'verification that the applicant has obtained, within the 12 months immediately preceding the date of application, a score of at least 70 percent on a mechanical administrator examination approved by the department' (12 AAC 39.012(a)(4)). The department's Mechanical Administrator by Examination instructions (form 08-4903) state that mechanical administrator license examinations are currently conducted by PSI Exams, that a candidate should contact PSI for scheduling, that a list of reference materials is available in PSI's Candidate Information Bulletin, and that examination results are valid for one year. By statute the department conducts licensing examinations at least twice each year at appropriate places in the state (AS 08.40.250), and the examination tests the applicant's ability to understand plans, design specifications, and engineering terms commonly used in the mechanical field; knowledge of mechanical installations and piping; familiarity with the Uniform Plumbing Code, Uniform Swimming Pool, Spa, and Hot Tub Code, Uniform Solar Energy Code, and Uniform Mechanical Code currently in effect in the state; and personal skill and ability (AS 08.40.270(a)). An applicant may not take the written examination more than three times within a 12-month period (12 AAC 39.033).
One contractor per administrator, and 15 days to report a change of employer: 'A person may not qualify or operate as a mechanical administrator for more than one registered contractor, corporation, joint venture, or other business entity unless the municipality or community where the person qualifies or operates as a mechanical administrator is the principal place of business of fewer than three mechanical administrators' (AS 08.40.280). The department adds on its application instructions that a mechanical administrator must be assigned to one of the entities referenced in AS 08.40.280 in order to practice, and that a licensee not practicing as a mechanical administrator may hold the license in an 'unassigned' status. A licensed mechanical administrator must notify the department in writing within 15 days after a change in mechanical administration employment or company affiliation, using the change of employer/affiliation form and a notarized statement naming the previous company and end date, the new company and start date, each company's construction contractor license number, and the administrator's license number (12 AAC 39.912).
Personal inspection and records of supervised work: A licensed mechanical administrator responsible for the installation or modification of mechanical piping and systems, devices, fixtures, equipment, or other mechanical materials, or for certifying that the work complies with applicable codes, 'shall personally inspect those materials after installation and modification unless the installation or modification amounts to simple or highly standardized work performed in less than 24 man-hours by personnel generally under the supervision of the mechanical administrator' (AS 08.40.400). Completion of work conducted under the license constitutes the administrator's certification that the work performed and materials used conform to applicable codes and standards, and the administrator must keep a signed record of supervised work on a department form, produce it on request, and retain it for at least three years from the date the certification statement is signed (12 AAC 39.902).
Bond, insurance, and the Alaska business license: Every contractor applicant files a surety bond running to the state at the time of applying for a certificate of registration; the amount for a mechanical or specialty contractor is $10,000 (AS 08.18.071(a), (b)(3)). A contractor whose work on one project has an aggregate contract price of $10,000 or less - where the work is not part of a larger operation or split up to evade a higher bonding requirement - bonds at $5,000 (AS 08.18.071(b)(4)); a cash deposit or other negotiable security acceptable to the commissioner may be filed in lieu of the bond (AS 08.18.071(c)). Insurance: public liability and property damage insurance covering Alaska contracting operations of not less than $20,000 for damage to property, $50,000 for injury including death to any one person, and $100,000 for injury including death to more than one person, which does not apply to an applicant whose projects each have an aggregate contract price of $2,500 or less; plus workers' compensation insurance to the extent required under AS 23.30 (AS 08.18.101(a)). The department's bond and insurance guidance form (08-4954) repeats these amounts and requires that the bond and insurance documents be issued by the bond or insurance company within 30 days of the date received by the division. Separately, any business operating in Alaska needs an Alaska business license: 'For the privilege of engaging in a business in the state, a person shall first apply ... and obtain a license' (AS 43.70.020(a)), at a fee of $50 a year, or $25 for a sole proprietorship whose sole proprietor is 65 or older during the license year or is a disabled veteran (AS 43.70.030(a)).
Fuel gas and fuel oil piping - a plumbing certificate of fitness applies to the individual: This is the Alaska trap for HVAC crews. Certificates of fitness are issued by a different agency - the Department of Labor and Workforce Development, Labor Standards and Safety Division, Mechanical Inspection Section - and by statute 'a person engaged in one of the following trades shall first obtain from the department the appropriate certificate of fitness in that trade: (1) electrical wiring subject to the standards established in AS 18.60.580; and (2) plumbing subject to the uniform plumbing code' (AS 18.62.070). HVAC and sheet metal work is not on that list, so there is no HVAC certificate of fitness in Alaska. But the regulation defining the plumber journeyman trade lists 'liquid and fuel gas piping' among the plumbing and drainage systems the certificate covers (8 AAC 90.900(14)(A)(vii)), and the department also issues a restricted certificate for exactly this work: 'A plumber restricted PG certificate of fitness authorizes the holder of the certificate to install fuel and gas piping within property lines of the premises' (8 AAC 90.135(a)), which requires at least 2,000 hours installing fuel and gas piping within property lines, a minimum of 4,000 hours of plumbing work subject to AS 18.60.705 and 8 AAC 63.010, and a passing examination (8 AAC 90.135(b)(1)). The department's own Mechanical Inspection pages state that its plumbing inspectors 'conduct inspections of work performed on new and altered plumbing, gas, and fuel piping installations in communities of 2,500 and above' and that 'with limited exceptions, to perform work subject to these standards a Certificate of Fitness is required.' Certificate fees are set by statute: a nonrefundable $50 application fee, $200 for the issuance of a trainee level certificate or renewal and $200 for the issuance of a journeyman level certificate or renewal, 'to be prorated if issued for less than two years', and $25 for a duplicate (AS 18.62.030(a); the proration clause trails the two-year journeyman certificate); a journeyman level certificate is valid two years and a trainee level certificate six years (AS 18.62.020(a)).
Where mechanical work stops and electrical work starts: A mechanical administrator in the unlimited HVAC/sheet metal category may supervise 'the installation or retrofitting of all pneumatic or electric controls and the retrofitting of all control wiring of 48 volts or less necessary for the operation of HVAC equipment or systems so long as those modifications do not alter the electrical characteristics of the mechanical system or controls. The original installation of control wiring, or the alteration or retrofitting of controls and control wiring that alters the electrical characteristics of the mechanical system, must be supervised by an electrical administrator licensed in the appropriate category under 12 AAC 32' (12 AAC 39.252(c)); the same boundary appears for the heating/cooling/process piping, refrigeration, temperature control, and residential HVAC categories (12 AAC 39.232(c), 39.272(b), 39.292, 39.332(c)). A mechanical administrator may not supervise the original installation of control wiring, or work that alters the electrical characteristics of the mechanical system, unless also licensed as an electrical administrator (12 AAC 39.942). Electrical wiring itself is a separate certificate-of-fitness trade under AS 18.62.070(1).
Renewal and continuing education: A mechanical administrator license is nontransferable and, unless revoked or suspended, may be renewed on a date set by the department upon proof of continued competency (AS 08.40.290(a)). To renew, the licensee submits a renewal application on a department form, the fee established in 12 AAC 02.245, and certification of compliance with the continuing education requirements of 12 AAC 39.400 - 12 AAC 39.460 (12 AAC 39.027). Continuing education is at least one eight-hour workshop, or an equivalent number of hours of a department-approved formal correspondence or individual study program, covering the applicable code for each category held - the Uniform Mechanical Code in effect in the state for the heating/cooling/process piping, unlimited HVAC/sheet metal, unlimited refrigeration, mechanical systems temperature control, and residential HVAC categories (12 AAC 39.410(b)(1)). The requirement is waived for a licensee who passed a licensing examination based on the appropriate codes or standards during the concluding licensing period (12 AAC 39.410(a)). A lapsed license may be reinstated on proof of continued competency plus all unpaid renewal fees and any penalty fee, but a license lapsed for more than two years requires the applicant to take the examination again (AS 08.40.290(b)).
Coming from another state - licensure by credentials: If an applicant submits proof satisfactory to the department that the applicant is licensed as a mechanical administrator or the equivalent by another state or territory, meets the qualifications established by the department for the category, and has passed an examination equivalent to the Alaska examination, 'the department shall waive all of the examination' (AS 08.40.270(b)). The corresponding application route is licensure by credentials (12 AAC 39.022; department form 08-4904), which requires verification of licensure sent directly to the department from every jurisdiction where the applicant holds or has held a mechanical administrator license, including an explanation of any disciplinary action, and verification of the out-of-state examination - including its content outline - sent directly by that state on the department's form. The department's own instructions caution that 'passing an exam in another state does not guarantee qualification of an applicant for an Alaska license' and that all other statutory and regulatory requirements must still be met.
Local government - permits, standards, and the bond rule: Alaska municipalities inspect and permit construction work, and the plumbing statutes expressly preserve local authority: they 'do not affect the authority of a municipality to prescribe by ordinance, rule, or order, standards for their respective areas of jurisdiction no less stringent than those established under AS 18.60.705' and 'are not intended to duplicate or preempt code administration or enforcement by municipalities' (AS 18.60.735). One state protection travels with the registration: 'A contractor or home inspector who is registered with the state under this chapter may not be required to give bond in applying for or holding a license issued by a political subdivision for a similar occupation' (AS 08.18.061). Confirm permit and inspection requirements with the municipality where the work will be performed.
Penalties for working unlicensed: A person who knowingly violates the mechanical administrator statutes, or a regulation or order of the department, or a code listed in AS 08.40.490(3)(A) that was in effect when the installation or repair was made, is guilty of a misdemeanor punishable by a fine of not more than $5,000 (AS 08.40.380(a)). The commissioner may issue a cease and desist order that remains in effect until the violation is corrected (AS 08.40.360) and may seek an injunction (AS 08.40.370); the department may also issue citations (AS 08.40.340). On the contractor side, a person acting as a contractor who knowingly violates the registration requirement in AS 08.18.011 after a prior conviction, citation finding, or administrative fine is guilty of a class B misdemeanor, and other violations of the chapter are punishable as violations (AS 08.18.141). The Department of Labor and Workforce Development's Mechanical Inspection Section investigates violations of Alaska's electrical and mechanical administrator requirements and forwards findings to the Division of Corporations, Business and Professional Licensing for enforcement.

Legal basis

Alaska Department of Commerce, Community, and Economic Development - Division of Corporations, Business and Professional Licensing (CBPL), Mechanical Administrators Program and Construction Contractors Program administers HVAC contractor licensing in Alaska. Every figure below is verified against the board’s own official pages and dated. Who must personally hold a credential — the contractor, the business, or the individual worker — is set out under Requirements.

What it’s called

Alaska does not issue anything called an ‘HVAC license,’ an HVAC journeyman license, or an HVAC technician license. Searches for an ‘Alaska HVAC license,’ ‘AC license,’ ‘mechanical license,’ or ‘HVAC contractor license’ resolve to a pair of state credentials issued by the Division of Corporations, Business and Professional Licensing (CBPL): the MECHANICAL CONTRACTOR certificate of registration, held by the contracting business under AS 08.18, and the MECHANICAL ADMINISTRATOR license, held by an individual under AS 08.40 in one or more named categories - for HVAC work usually ‘Unlimited HVAC/Sheet Metal’ (category code UHVCS) or ‘Residential HVAC’ (RHVC), and sometimes ‘Unlimited Refrigeration’ (UR), ‘Heating, Cooling and Process Piping’ (HCPP), or ‘Mechanical Systems Temperature Control’ (CNTL). Because the registration is what authorizes the business to bid and work, and the administrator is the individual who qualifies that registration, an HVAC installer or service technician employed by a registered mechanical contractor needs no personal state HVAC credential. Two other Alaska credentials are commonly confused with the HVAC license and are issued by a different agency - the Department of Labor and Workforce Development’s Mechanical Inspection Section - as ‘certificates of fitness’: the plumber journeyman certificate and the plumber restricted PG certificate, which is what an individual needs to install fuel and gas piping within property lines. There is also an ’electrical administrator’ license (AS 08.40.005 - 08.40.200) that is the electrical-trade counterpart of the mechanical administrator and is not an HVAC credential. Separately, EPA Section 608 refrigerant-handling certification is a FEDERAL credential held by the individual technician; it is neither issued by Alaska nor a substitute for any Alaska license.

License types & fees

Type	Experience	Exam	Fee
Mechanical Contractor - certificate of registration (the business-level credential)	Held by the contracting business, not by a worker. 'A person may not submit a bid or work as a contractor until that person has been issued a certificate of registration as a contractor by the department' (Alaska Statute 08.18.011(a)), and a 'mechanical contractor' is defined as a contractor whose business operations involve 'plumbing, pipe fitting, sheet metal, heating, air conditioning, ventilating, or sprinkler and dry chemical fire protection trades' in order to install or modify mechanical piping and systems, devices, fixtures, and equipment or other mechanical materials subject to the Uniform Plumbing Code, the Uniform Swimming Pool, Spa, and Hot Tub Code, the Uniform Solar Energy Code, and the Uniform Mechanical Code (AS 08.18.171(13)). The registration itself carries no experience requirement; instead, 'the department may not issue a certificate of registration as a mechanical contractor to an applicant unless the applicant is, or employs, a person currently licensed as a mechanical administrator under AS 08.40' (AS 08.18.028(a)). A mechanical contractor may employ more than one mechanical administrator (AS 08.18.028(b)); if the relationship with the only mechanical administrator ends, the registration is void 30 days after the next regularly scheduled mechanical administrator examination unless a licensed replacement is hired in the interim (AS 08.18.028(c)).	No examination is attached to the contractor registration itself. Trade competency is supplied by the mechanical administrator the business is or employs. (The residential contractor endorsement examination under AS 08.18.025 applies to general contractors building one-to-four-unit residential structures, not to the mechanical classification.)	Nonrefundable application fee for initial registration $100.00; certificate of registration and license enforcement support fee, for all or part of the initial biennial registration period, $250.00; biennial certificate of registration renewal and license enforcement support fee $250.00 (Alaska Administrative Code 12 AAC 02.180(a)(1)-(3)). Related charges in the same fee section: change from one specialty to another, or from specialty to mechanical or mechanical to specialty, $35.00; change between a specialty or mechanical registration and a general contractor registration $75.00; 'doing business as' (dba), owner, or entity change $65.00; bonding research $30.00. Beyond the fee, a mechanical contractor must file a $10,000 surety bond (AS 08.18.071(b)(3)) and proof of public liability and property damage insurance of at least $20,000 for damage to property, $50,000 for injury including death to any one person, and $100,000 for injury including death to more than one person, plus workers' compensation insurance to the extent required under AS 23.30 (AS 08.18.101(a); CBPL form 08-4954, 'Guidance on Required Bond or Insurance Documentation').
Mechanical Administrator - Unlimited HVAC/Sheet Metal (category code UHVCS)	An individual license. Qualifying paths, each proved to the department's satisfaction (12 AAC 39.242): practical experience as a journeyman in HVAC and sheet metal work for at least four of the six years immediately preceding the application; management experience in HVAC and sheet metal work as a field superintendent or similar position for at least four of the six years immediately preceding the application; a degree in mechanical engineering from a nationally or regionally accredited college or university plus practical experience as a journeyman or field engineer in HVAC and sheet metal work for at least one of the three years immediately preceding the application; or registration in the state as a professional mechanical engineer plus management experience in the mechanical contracting industry as a field engineer or similar engineering position for at least one of the three years immediately preceding the application. A 'year of experience' means at least 1,500 hours worked in the required field or position within a 12-consecutive-month period (12 AAC 39.950). Scope (12 AAC 39.252): installation, alteration, or retrofitting of all components of the air handling and refrigeration cycle - fans, coils, evaporative cooling units, self-contained packaged air conditioning and heating units, air handling units, condensing units, furnaces, flues, chimneys, duct work, cooled mechanical air handling and ventilation applications and related accessories - plus fuel oil tanks and piping and fuel gas piping, plus heating/cooling/process piping and mechanical-systems temperature-control work where integral to work on an HVAC system (12 AAC 39.252(a)(2)-(3)), and the residential HVAC category in full (12 AAC 39.252(a)(4), which carries no such qualifier).	A score of at least 70 percent on a mechanical administrator examination approved by the department, obtained within the 12 months immediately preceding the date of application (12 AAC 39.012(a)(4)). The department's Mechanical Administrator by Examination application instructions (form 08-4903) state that the examinations are conducted by PSI Exams and that examination results are valid for one year. An applicant may not take the written examination more than three times within a 12-month period (12 AAC 39.033).	Nonrefundable application fee $150.00 for each license category applied for separately, plus a license fee of $200.00 for all or part of the initial biennial license period - $350.00 total to apply, as stated on the department's own application instructions (form 08-4903, new 08/30/2024) and matching the fee regulation 12 AAC 02.245(1) and (3). Biennial renewal $200.00 (12 AAC 02.245(4)); the current renewal form (08-4296, revised 10/23/2025) shows $200.00 for licenses first issued on or before December 31, 2024 and a prorated $100.00 for licenses first issued on or after January 1, 2025. Adding a category to an existing license costs another $150.00 application fee (form 08-4905).
Mechanical Administrator - Residential HVAC (category code RHVC)	The applicant must furnish proof satisfactory to the department of 'practical experience as a journeyman in residential HVAC work for at least two of the four years immediately preceding the date of the application' (12 AAC 39.322). Scope (12 AAC 39.332(b)): residential HVAC work includes the installation, alteration, or retrofitting of fuel gas piping downstream of the gas meter, or fuel tank and fuel oil piping that is integral to work on an HVAC system for a single-family dwelling or a duplex dwelling not exceeding three stories; and warm air heating systems not exceeding 240,000 B.T.U./hour input. A mechanical administrator licensed in the unlimited HVAC/sheet metal category may also perform or supervise mechanical work on a residential dwelling (12 AAC 39.332(d)).	Same requirement as every mechanical administrator category: at least 70 percent on a department-approved mechanical administrator examination within the 12 months before applying (12 AAC 39.012(a)(4)), taken through PSI Exams per the department's application instructions. Adding this category to an existing mechanical administrator license requires passing the examination for that category (12 AAC 39.025).	$150.00 nonrefundable application fee per category applied for separately plus the $200.00 license fee for all or part of the initial biennial period (12 AAC 02.245(1), (3); form 08-4903); $200.00 biennial renewal (12 AAC 02.245(4)).

Who does NOT need this license — exemptions

Alaska’s HVAC exemptions live in three separate places, and an exemption from one does not carry over to the others: AS 08.40.390 excludes people from the MECHANICAL ADMINISTRATOR requirement, AS 08.18.161 exempts people from the CONTRACTOR REGISTRATION requirement, and AS 18.60.735 and AS 18.60.715 limit the reach of the state PLUMBING CODE and, with it, the plumbing certificate of fitness. MECHANICAL ADMINISTRATOR EXCLUSIONS (AS 08.40.390): subsection (a) provides that the mechanical administrator statutes ‘do not apply to a utility, municipality, or local governing body whose employees are engaged in mechanical work on an integral part of a system owned and operated by the utility, municipality, or local governing body.’ Subsection (b) provides that they ‘do not apply to a person engaged in’ - (1) ’the manufacture or repair of mechanical apparatus or equipment’; (2) ‘mechanical work, the cost of which does not exceed $50,000, involving residences or small commercial establishments in communities that (A) have a population of under 5,000 according to the latest available federal or state census or other census approved by the department; or (B) are over 50 miles by air or water transportation from the business place of a mechanical administrator licensed under AS 08.40.210 - 08.40.490’; (3) ‘mechanical installation on a single-family residence or a two-family residence that is not intended for sale at the time of making the installation’; (4) ‘installation of water lines or sanitary, storm, or drain sewer lines more than five feet from a building’; (5) ‘mechanical maintenance or repair work if the work is performed by the person as an employee of an owner or tenant of commercial property as part of the employee’s work duties with respect to the property but is not offered or performed as a service to the public’; and (6) ‘design, installation, maintenance, or repair of fire extinguishing systems.’ Note how narrow (3) and (5) actually are: (3) turns on the residence not being intended for sale at the time of the installation, and (5) turns on the work being the person’s employee duties for the property owner or tenant and not being offered or performed as a service to the public. CONTRACTOR REGISTRATION EXEMPTIONS (AS 08.18.161) - ‘To the extent that this chapter governs contractors, this chapter does not apply to’: an authorized representative of the United States government, the state, or a political subdivision or agency of the state; an officer of a court when acting within the scope of office; ‘a public utility operating under the regulations of the Regulatory Commission of Alaska in construction, maintenance, or development work incidental to its own business’; construction, repair, or operation incidental to discovering or producing petroleum or gas, or to drilling, testing, abandoning, or other operation of a petroleum or gas well or a surface or underground mine or mineral deposit ‘when performed by an owner or lessee’; ’the sale or installation of finished products, materials, or articles of merchandise that are not actually fabricated into and do not become a permanent, fixed part of a structure’; ‘construction, alteration, or repair of personal property’; a person who only furnishes materials, supplies, or equipment ‘without fabricating them into, or consuming them in the performance of, the work of the contractor’; ‘an owner who contracts for a project with a registered contractor’; ‘a person working on an existing structure on that person’s own property, whether occupied by the person or not, and a person working on that person’s own existing residence, whether owned by the person or not’; ‘an owner or tenant of commercial property who uses the owner’s or tenant’s own employees to do maintenance, repair, and alteration work on that property’; an owner acting as the owner’s own contractor who performs the work independently or hires workers or subcontractors, purchases materials, and sees to paying for all labor, subcontractors, and materials - but ’the owner shall be limited to construction of one home, duplex, triplex, four-plex, or commercial building every two years,’ and an owner who advertises the structure for sale or sells it during construction or within two years after construction begins must file a notice on department forms that the owner is not engaged in a business requiring registration; and ‘a person performing construction work incidental to farming, dairying, agriculture, horticulture, stock or poultry raising, mining, logging, fishing, clearing, or other work on the land in rural districts for fire prevention purposes, or access road building, unless the person is a licensee.’ PLUMBING CODE AND CERTIFICATE-OF-FITNESS LIMITS: ‘An organized municipality or unorganized village having less than 2,500 population is exempt from the provisions of AS 18.60.705 - 18.60.740’ (AS 18.60.735), and ’nothing in AS 18.60.705 - 18.60.740 prohibits a person from performing plumbing work on the person’s own property’ (AS 18.60.715(c)). The department may also grant exceptions from specific code provisions ‘where distance or other factors make implementation impractical,’ with specific consideration for outlying villages and sparsely populated areas to ensure the code does not impose an undue financial burden (AS 18.60.710). On the certificate-of-fitness statute itself, AS 18.62.010 requires a certificate for work subject to the AS 18.60.580 electrical and AS 18.60.705 plumbing standards ’except that a certificate of fitness may not be required of employees of an electric utility that does not have within its service area any portion of a city or unified municipality having more than 2,500 population.’ Finally, one limit inside the licensing structure rather than outside it: ‘only sheet metal work directly related to heating, ventilation, and air conditioning systems, and any work covered by the Uniform Mechanical Code, is required to be supervised by a mechanical administrator licensed in the HVAC/sheet metal category’ (12 AAC 39.252(e)).

Fees

Two sets of state fees apply, one to the individual mechanical administrator and one to the contracting business. MECHANICAL ADMINISTRATOR (12 AAC 02.245): nonrefundable application fee $150.00 for each license category applied for separately; mechanical administrator license fee $200.00 for all or part of the initial biennial license period; biennial license renewal fee $200.00. The department’s own application instructions (form 08-4903 for licensure by examination and form 08-4904 for licensure by credentials, both new 08/30/2024) state the total due to apply as $150.00 application plus $200.00 license fee = $350.00, and the additional-category application (form 08-4905) charges the $150.00 application fee again. The current renewal form (08-4296, revised 10/23/2025) charges $200.00 to renew for the January 1, 2026 - December 31, 2027 period for licenses first issued on or before December 31, 2024, and a prorated $100.00 for licenses first issued on or after January 1, 2025. A license verification sent to another board or agency carries a $20 filing fee. MECHANICAL CONTRACTOR REGISTRATION (12 AAC 02.180(a)): nonrefundable application fee for initial registration $100.00; certificate of registration and license enforcement support fee for all or part of the initial biennial registration period $250.00; biennial renewal and license enforcement support fee $250.00; change from one specialty to another, or specialty to mechanical or mechanical to specialty, $35.00; change between a specialty or mechanical registration and a general contractor registration $75.00; dba, owner, or entity change $65.00; bonding research $30.00. An application fee is not refundable (12 AAC 02.010(e)). OTHER COST COMPONENTS an Alaska HVAC business must budget for: the $10,000 mechanical contractor surety bond (AS 08.18.071(b)(3)); public liability and property damage insurance of at least $20,000 property / $50,000 one person / $100,000 more than one person and workers’ compensation insurance where required (AS 08.18.101(a)); the PSI examination fee, which is paid to the testing vendor and is not set in the fee regulation; an Alaska business license at $50 a year, or $25 for a sole proprietor who is 65 or older during the license year or a disabled veteran (AS 43.70.030(a)); and, for anyone personally installing fuel and gas piping, the plumbing certificate of fitness fees set in AS 18.62.030(a) - a nonrefundable $50 application fee, $200 for a trainee level certificate or renewal and $200 for a journeyman level certificate or renewal ’to be prorated if issued for less than two years’, and $25 for a duplicate (the proration clause trails the two-year journeyman certificate).

Exam

Alaska’s HVAC examination belongs to the individual mechanical administrator, not to the contracting business - the mechanical contractor registration itself has no trade examination. A complete application for a mechanical administrator license by examination must include ‘verification that the applicant has obtained, within the 12 months immediately preceding the date of application, a score of at least 70 percent on a mechanical administrator examination approved by the department’ (12 AAC 39.012(a)(4)). The department’s Mechanical Administrator by Examination application instructions (form 08-4903, new 08/30/2024) state that mechanical administrator license examinations are currently being conducted by PSI Exams, that candidates contact PSI for scheduling, that a list of reference materials for the examination is available in PSI’s Candidate Information Bulletin, and that examination results are valid for one year. Each category has its own examination, and a licensee adding a category must pass the examination for that category (12 AAC 39.025). By statute the department conducts licensing examinations at least twice each year at appropriate places in the state (AS 08.40.250), and each applicant is examined on the ability to understand plans, design specifications, and engineering terms commonly used in the mechanical field; knowledge of mechanical installations and piping; familiarity with the Uniform Plumbing Code, Uniform Swimming Pool, Spa, and Hot Tub Code, Uniform Solar Energy Code, and Uniform Mechanical Code currently in effect in the state; and personal skill and ability (AS 08.40.270(a)). An applicant may not take the written examination more than three times within a 12-month period (12 AAC 39.033). An applicant already licensed as a mechanical administrator or the equivalent in another state or territory, who meets Alaska’s category qualifications and has passed an equivalent examination, has the Alaska examination waived (AS 08.40.270(b)) and applies by credentials instead (12 AAC 39.022; form 08-4904). The examination fee is paid to the testing vendor and is not published in the department’s fee regulation; confirm the current amount with PSI before scheduling.

Renewal & continuing education

MECHANICAL ADMINISTRATOR: a biennial license. A license is nontransferable and, unless revoked or suspended, may be renewed on a date set by the department upon proof of continued competency (AS 08.40.290(a)); the fee regulation sets a ‘biennial mechanical administrator license renewal fee’ and a license fee for ‘all or part of the initial biennial license period’ (12 AAC 02.245(3)-(4)). The department’s current renewal form (08-4296, revised 10/23/2025) identifies the license period as January 1, 2026 through December 31, 2027 and states plainly: ‘Your license lapses after December 31, 2025. There is no grace period - it is illegal to work if your license has lapsed.’ Renewal requires the renewal application, the fee, and certification of compliance with the continuing education requirements (12 AAC 39.027); for the period that closed on December 31, 2025 the continuing education had to be completed between January 1, 2024 and December 31, 2025 - though the renewal form also carries a late-completion attestation: as allowed under 12 AAC 02.965, a renewing administrator who did not complete all requirements during that period may certify continuing education completed on or after January 1, 2026. A lapsed license may be reinstated on proof of continued competency plus all unpaid renewal fees and any penalty fee established under AS 08.01.100(b), but ‘if a person’s license has been lapsed for more than two years, the person is required to take an examination under AS 08.40.270’ (AS 08.40.290(b)). MECHANICAL CONTRACTOR REGISTRATION: also biennial - the fee regulation sets a registration fee ‘for all or part of the initial biennial registration period’ and a ‘biennial certificate of registration renewal’ fee (12 AAC 02.180(a)(2)-(3)) - and renewal is under the same requirements as an original registration (AS 08.18.031(a)), including current bonding and insurance (12 AAC 21.070). The specific calendar expiration date of the contractor registration period is published on the division’s renewal notices and self-service portal rather than in the statutes or the fee regulation; confirm it with the Construction Contractors program before renewing. Renewal itself requires the 12 AAC 21.070 package: the renewal application, the fee under 12 AAC 02.180, current bonding, current public liability and property damage insurance, and workers’ compensation coverage where required. The five-year reinstatement window is narrower than it sounds and sits elsewhere: under 12 AAC 21.043(c), a registered contractor THAT HAS FILED THE WRITTEN NOTICE of dissolution or cessation of business activities under 12 AAC 21.043(a) may reinstate a lapsed registration not later than five years after the expiration date. Eight hours per licensing period, per code, for mechanical administrators. An applicant for renewal must document satisfactory completion of the continuing education requirements during the concluding licensing period, unless the licensee passed a licensing examination based upon the appropriate codes or standards during that period (12 AAC 39.410(a)). The requirement itself: ‘A mechanical administrator must satisfactorily complete at least one eight-hour continuing education workshop or an equivalent number of hours of a formal correspondence or individual study program approved by the department that covers the following codes or standards applicable to each category of license held’ - the Uniform Mechanical Code in effect in the state at the time the hours are completed, for the heating/cooling/process piping, unlimited HVAC/sheet metal, unlimited refrigeration, mechanical systems temperature control, and residential HVAC categories; the Uniform Plumbing Code as adopted under AS 18.60.705 for the unlimited commercial and industrial plumbing category; and either code for the residential plumbing and hydronic heating category (12 AAC 39.410(b)). A workshop must cover the edition of the applicable code in effect in the state when the workshop is presented (12 AAC 39.420(a)). Workshops sponsored by the Alaska Mechanical Contractors Association; the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States and Canada; the International Association of Plumbing and Mechanical Officials; the International Conference of Building Officials; the Sheet Metal and Air Conditioning Contractors’ National Association; or the Alaska Department of Labor and Workforce Development are considered approved if they meet that requirement, and any other sponsor’s workshop must be individually approved by the department (12 AAC 39.420(b)-(c)). Credit hours for a formal correspondence or individual study program are determined by the department on an individual basis (12 AAC 39.430). The licensee certifies compliance on a department form at renewal, and falsifying that evidence is grounds for disciplinary action (12 AAC 39.440). A licensee prevented from completing the hours by circumstances beyond the licensee’s control may request a waiver in writing, and the department may prescribe an alternative method of compliance (12 AAC 39.450). Continuing education attaches to the mechanical administrator license, not to the mechanical contractor registration.

Frequently asked questions

Does Alaska require an HVAC license?

Yes, but not a license in the technician’s own name. Alaska licenses HVAC at the state level through two linked credentials issued by the Division of Corporations, Business and Professional Licensing (CBPL): the contracting business must hold a certificate of registration as a MECHANICAL CONTRACTOR (AS 08.18.011(a); AS 08.18.171(13)), and that registration cannot be issued unless the business ‘is, or employs, a person currently licensed as a mechanical administrator under AS 08.40’ (AS 08.18.028(a)). The mechanical administrator is an individual license, and ‘a person may not act as a mechanical administrator without a license unless the person is covered by an exclusion under AS 08.40.390’ (AS 08.40.260(a)). An HVAC installer or service technician working for a registered mechanical contractor does not need a personal state HVAC credential - Alaska issues no HVAC journeyman or HVAC technician license.

What is a mechanical administrator, and which category covers HVAC?

A mechanical administrator is the licensed individual responsible for installing or modifying mechanical piping and systems, devices, fixtures, equipment, or other mechanical materials subject to the Uniform Plumbing, Uniform Swimming Pool/Spa/Hot Tub, Uniform Solar Energy, and Uniform Mechanical Codes, or for certifying that the work complies with those codes (AS 08.40.490(3)). CBPL publishes these categories: Heating, Cooling and Process Piping (HCPP); Unlimited HVAC/Sheet Metal (UHVCS); Residential HVAC (RHVC); Unlimited Refrigeration (UR); Mechanical Systems Temperature Control (CNTL); Unlimited Commercial and Industrial Plumbing (UCIP); and Residential Plumbing and Hydronic Heating (RPHH). For HVAC the usual license is Unlimited HVAC/Sheet Metal; Residential HVAC covers single-family and duplex dwellings not exceeding three stories with warm air heating up to 240,000 B.T.U./hour input. You may only perform work in a category you hold (AS 08.40.260(b)).

What experience and exam does Alaska's HVAC mechanical administrator license require?

For the Unlimited HVAC/Sheet Metal category, the applicant must prove one of these to the department’s satisfaction: practical experience as a journeyman in HVAC and sheet metal work for at least four of the six years immediately preceding the application; management experience in HVAC and sheet metal work as a field superintendent or similar position for at least four of the six years; a mechanical engineering degree plus at least one of the three preceding years as a journeyman or field engineer in HVAC and sheet metal work; or registration in Alaska as a professional mechanical engineer plus at least one of the three preceding years of management experience in the mechanical contracting industry (12 AAC 39.242). A ‘year of experience’ is at least 1,500 hours within a 12-consecutive-month period (12 AAC 39.950). The applicant must also score at least 70 percent on a department-approved mechanical administrator examination within the 12 months before applying (12 AAC 39.012(a)(4)); CBPL’s application instructions say those examinations are conducted by PSI Exams and that results are valid for one year. The Residential HVAC category instead requires two of the four years immediately preceding the application as a journeyman in residential HVAC work (12 AAC 39.322).

How much does an Alaska HVAC license cost?

For the individual mechanical administrator: a $150.00 nonrefundable application fee for each license category applied for separately plus a $200.00 license fee for all or part of the initial biennial period - $350.00 total, as stated on CBPL’s own application instructions (form 08-4903) and in the fee regulation 12 AAC 02.245. Renewal is $200.00 biennially, or a prorated $100.00 for a license first issued on or after January 1, 2025 (renewal form 08-4296, revised 10/23/2025). Adding a category costs another $150.00. For the business: a $100.00 nonrefundable application fee plus $250.00 for the registration for all or part of the initial biennial period, then $250.00 biennially (12 AAC 02.180(a)). On top of those, budget the PSI examination fee (paid to the testing vendor), a $10,000 surety bond, public liability and property damage insurance of at least $20,000/$50,000/$100,000 plus workers’ compensation where required, and an Alaska business license at $50 a year.

Does Alaska require continuing education for HVAC licensees?

Yes, for the mechanical administrator. Each licensing period the administrator must complete at least one eight-hour continuing education workshop, or an equivalent number of hours of a department-approved formal correspondence or individual study program, covering the code applicable to each category held - the Uniform Mechanical Code in effect in the state for the HVAC/sheet metal, refrigeration, heating/cooling/process piping, temperature control, and residential HVAC categories (12 AAC 39.410(b)). Workshops sponsored by the Alaska Mechanical Contractors Association, the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry, IAPMO, the International Conference of Building Officials, SMACNA, or the Alaska Department of Labor and Workforce Development are pre-approved if they cover the code edition in effect; any other sponsor needs individual approval (12 AAC 39.420). The requirement is waived if the licensee passed a licensing examination based on the appropriate codes during the concluding period, and a licensee prevented by circumstances beyond their control may request a written waiver (12 AAC 39.410(a); 12 AAC 39.450). The mechanical contractor registration itself carries no continuing education requirement.

Do I need anything extra to run gas piping for a furnace in Alaska?

Very likely yes, and it is the requirement HVAC crews miss. Certificates of fitness are issued by a different agency - the Department of Labor and Workforce Development’s Mechanical Inspection Section - and by statute they are required in two trades: electrical wiring and plumbing (AS 18.62.070). There is no HVAC certificate of fitness. But Alaska’s definition of the plumbing trade puts ’liquid and fuel gas piping’ inside plumbing and drainage systems (8 AAC 90.900(14)(A)(vii)), and the department issues a restricted certificate for exactly this work: ‘A plumber restricted PG certificate of fitness authorizes the holder of the certificate to install fuel and gas piping within property lines of the premises’ (8 AAC 90.135(a)). The department’s own pages say its plumbing inspectors inspect plumbing, gas, and fuel piping installations in communities of 2,500 and above, and that with limited exceptions a certificate of fitness is required to perform work subject to those standards. Separately, EPA Section 608 refrigerant certification is a FEDERAL requirement for technicians who handle refrigerants and is not an Alaska license.

Are there places in Alaska where the HVAC licensing rules do not apply?

Yes, and the geography-based carve-outs are unusually broad. The mechanical administrator statutes do not apply to a person engaged in ‘mechanical work, the cost of which does not exceed $50,000, involving residences or small commercial establishments in communities that (A) have a population of under 5,000 according to the latest available federal or state census or other census approved by the department; or (B) are over 50 miles by air or water transportation from the business place of a mechanical administrator licensed under AS 08.40.210 - 08.40.490’ (AS 08.40.390(b)(2)), nor to ‘mechanical installation on a single-family residence or a two-family residence that is not intended for sale at the time of making the installation’ (AS 08.40.390(b)(3)). On the plumbing-code side, ‘an organized municipality or unorganized village having less than 2,500 population is exempt from the provisions of AS 18.60.705 - 18.60.740’ (AS 18.60.735). These exclusions do not waive the separate contractor registration requirement in AS 08.18, which has its own exemption list in AS 08.18.161.
