Requirements below are drawn from Vermont Department of Public Safety, Division of Fire Safety - Electricians' Licensing Board (26 V.S.A. ch. 15), Plumber's Examining Board (26 V.S.A. ch. 39), and the Division's certificates of fitness for gas and oil-burning equipment (20 V.S.A. 2731) (official site) and last verified July 25, 2026. Boards change fees and rules often — confirm before acting.

Requirements at a glance

What Vermont actually licenses - no HVAC licence, but several credentials an HVAC technician needs: Vermont issues no licence called an HVAC, air conditioning, refrigeration or mechanical-contractor licence. The Secretary of State's Office of Professional Regulation publishes what it calls 'a comprehensive list of the various professions regulated by the Vermont Office of Professional Regulation,' and no HVAC, mechanical, refrigeration or air-conditioning profession appears on it; the same page directs 'Plumbers and Electricians' to the Department of Fire Safety as outside OPR's jurisdiction. The Division of Fire Safety, in turn, publishes the full ledger of trade licences and certifications it administers, and there is no HVAC line there either. What Vermont does instead is regulate HVAC work through the trades it touches: the ELECTRICAL side through Type-S journeyman specialty classes A1 (automatic gas or oil heating, including geo-thermal and ground source heat pumps) and C3 (refrigeration or air conditioning, air to air heat pumps); the FUEL side through Division certificates of fitness for gas and for oil-burning equipment; the HYDRONIC side through the P2 Heating System Specialist plumbing licence; and, above a dollar threshold, the CONTRACTING relationship through OPR residential contractor registration.
Who must hold the credential - the individual technician: Every credential above is issued to an individual person, not to a company. Electrical licences are issued 'in the form of a wallet-size card' that 'shall be carried by the ... electrician while performing his or her trade and shall be displayed upon request' (26 V.S.A. 902(b), 903(c), 904(b); Electrical Safety Rules 3.1-3.3). Plumbing specialist licences are the same: the card 'shall be carried by the licensee at all times while performing the licensee's specialty and shall be displayed upon request' (26 V.S.A. 2192a(a)). The gas and oil credentials are certificates of fitness held by 'individuals performing activities related to fire or life safety' (20 V.S.A. 2731(c)(4)), and the Division states that 'all individuals engaged in the inspection, installation, and service of Propane (LP) or Natural Gas systems must be certified.' Employer licensure does not substitute: a specialty business 'may hire or employ only people licensed in the specialty of the business' (26 V.S.A. 2192a(c)). The one business-level credential is OPR residential contractor registration, which may be held by an individual ($75.00) or a business organization ($250.00) and which exempts 'an employee acting within the scope of his or her employment for a business organization registered under this chapter' (26 V.S.A. 5502(1)).
The residential two-unit line - where an electrical licence stops being required: This is the single most consequential boundary for HVAC work in Vermont. The 2025 Vermont Electrical Safety Rules open Section 3 with it: 'With limited exceptions, anyone performing electrical work in the State of Vermont, other than in a residential building containing two or fewer dwelling units or electrical work regulated under the National Electrical Code, article 800, Communications Circuits, is required to be licensed as an electrician.' The statute behind it is 26 V.S.A. 910(6), which requires no licence for 'any electrical work in a building used for dwelling or residential purposes that contains no more than two dwelling units.' So the electrical portion of a furnace, heat pump or air conditioner installed in a single-family home or a duplex needs no Vermont electrical licence - while the same work in an apartment building, a store, an office or a plant does. Nothing in that exemption touches the gas certificate of fitness, the oil certificate of fitness, the plumbing specialist licence, the residential contractor registration threshold, or federal refrigerant rules.
Gas and oil work - the certificate of fitness is the operative credential: The Division of Fire Safety states plainly that 'all individuals engaged in the inspection, installation, and service of Propane (LP) or Natural Gas systems must be certified as required under the Vermont Fire and Building Safety Code,' and 20 V.S.A. 2731(c)(4) establishes 'three-year initial certificate of fitness and renewal fees for individuals performing activities related to fire or life safety.' The gas categories track what an HVAC technician actually does - Natural Gas Installer (installation, inspection and service of natural fuel gas systems), LP Gas Installer (installation, inspection, service), and Both - and qualification is by documented completion of the AGA course of study and/or National Propane Gas Association CETP sections, now transitioning to the PEP module program with existing CETP certificates carried forward. Oil-fired heating is certified separately by NORA certificate level: Silver for the full Oil Burning Equipment Installer certification, Bronze for the Limited certification. Both the gas and oil certifications carry an 8-hour continuing education requirement over the previous three years, and both are $60.00.
Hydronic heating pulls in the plumbing side: Vermont splits hot-water and steam space heating away from the electrical and fuel credentials and puts it under the Plumber's Examining Board. The P2 Heating System Specialist covers 'installation, replacement, and repair of residential, industrial, or commercial hydronic space heating systems, including radiant, solar, and other types of hydronic system design,' with steam work 'limited to steam systems with operating pressure not to exceed 15 PSIG' (26 V.S.A. 2192a(b)(2)). The companion P1 Water Heater Specialist covers domestic hot water supply tanks. The Division's plumbing program describes its own purpose as protecting health and welfare 'in the fields of environmental sanitation, water treatment, domestic supply and hydronically related hot water heating ... by licensing qualified plumbers and qualified heating and water treatment specialists' (the current 2025 Vermont Plumbing Rules, Section 1, phrase the fields more broadly: 'domestic hot and cold water supply/distribution piping and hydronically related heating systems'), and states that the rules apply to all public buildings whether or not connected to public water or sewage systems, and to all other buildings or facilities connected to a public water or sewage system - and on coverage of owner-occupied homes the Division's plumbing PAGE and the current rules conflict, and the dated rules control: the page still says owner-occupied single-family residences not on public water or sewage systems 'are not covered by these rules', but the 2025 Vermont Plumbing Rules (effective 11/04/2025), Section 2 (Scope), state 'These rules shall apply to all public buildings, whether or not they are connected to a public water system or a public sewerage system', that 'This includes owner-occupied single-family residences', and that owner-occupied single-family residences which are not connected 'do not require a work notice' - so the rules DO cover owner-occupied homes; what an off-system owner-occupied residence is excused from is the work notice, not the rules.
Refrigerant handling is federal, not a Vermont credential: Vermont's C3 specialty class is an ELECTRICAL licence covering refrigeration and air conditioning work; it is not a refrigerant-handling credential. Under the Clean Air Act and 40 CFR part 82, subpart F, technicians who maintain, service, repair or dispose of equipment that could release refrigerant must hold EPA Section 608 certification. That is a federal credential held by the individual technician, it applies everywhere in Vermont, and it neither substitutes for nor is satisfied by any Division of Fire Safety licence or certificate of fitness.
The Vermont Energy Goals education module - a condition on every one of these credentials: Act S.220 of the 2020 legislative session added an education module requirement that reaches electricians, plumbers, gas certificants and oil certificants alike. The module 'shall be not more than two hours and shall be required as a condition of initial licensure and license renewal' (26 V.S.A. 905(h)(1) for electricians and 2193(f)(1) for plumbers - the latter adding that masters and journeymen who complete it need not repeat it for an additional specialty license; for gas and oil certificants, 20 V.S.A. 2731(a)(2)(B) phrases the same requirement as a condition of certification); the initial-licensure version provides general information regarding the State's energy goals, and the renewal version provides updates on the State's energy goals and corresponding State energy programs applicable to the profession (26 V.S.A. 905(h), 26 V.S.A. 2193(f), 20 V.S.A. 2731(a)(2)). The certificant categories named in the fire-safety statute are gas appliance installers, inspectors and servicers; oil burning equipment installers, inspectors and servicers; and limited oil burning equipment installers, inspectors and servicers (20 V.S.A. 2731(a)(2)(A)). The Division states that anyone applying for or renewing a licence or certification after July 1, 2021 must complete the module and include a copy of the completion certificate with the application. Master and journeyman plumbers who complete the module are not required to complete it again for any additional specialty licence (26 V.S.A. 2193(f)(1)).
Reciprocity and endorsement: On the electrical side, a person previously issued a master or journeyman electrician licence by another state whose standards are equivalent to Vermont's, where that state grants a similar privilege to Vermont licensees, shall be issued a licence without examination on payment of the required fee (26 V.S.A. 906(b)(1)); the Electrical Safety Rules describe this as a Universal licence and require the licence to have been held in good standing for 3 years. Beyond that, 'the Board shall issue a license to master and journeyman electricians who have been licensed in good standing in another jurisdiction within the United States for at least three years, regardless of whether that jurisdiction meets the reciprocity requirements' (26 V.S.A. 906(b)(2)(A)). The 2025 Electrical Safety Rules add two notes: 'Reciprocal agreements for residents of New Hampshire and Maine obtaining licenses in Vermont remain in place,' and 'Vermont has joined the National Electrical Reciprocal Alliance. An electrical license held in a NERA member state shall be held and in good standing for 1 year in order to apply for a Vermont electricians license.' A journeyman's licence shall also be issued to a service member or veteran who submits a complete application, has received U.S. Armed Forces designation as a 12R electrician or equivalent, and has completed a minimum of 8,000 hours and four years of active duty field work in that role (26 V.S.A. 906(c)). Note that the reciprocity provisions in 26 V.S.A. 906(b) speak to master's and journeyman's licences; the Division's application form offers two routes on the Specialist line - Reciprocal (Maine or New Hampshire residents only, with certified letters and license photocopies) and Universal; the Reciprocal Military route appears only under Master and Journeyman, matching 26 V.S.A. 906(c).

Legal basis

Vermont Department of Public Safety, Division of Fire Safety - Electricians’ Licensing Board (26 V.S.A. ch. 15), Plumber’s Examining Board (26 V.S.A. ch. 39), and the Division’s certificates of fitness for gas and oil-burning equipment (20 V.S.A. 2731) administers HVAC technician licensing in Vermont. 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

Vermont issues nothing called an ‘HVAC licence’ - a search for one lands on whichever of four separate credentials the work requires, and Vermonters name them by their class codes. On the ELECTRICAL side the Division of Fire Safety’s licensing ledger lists ‘A1 - Automatic Gas / Oil Heating’ and ‘C3 - Refrigeration and Air Conditioning’; formally these are Type-S journeyman electrician specialty licences (26 V.S.A. 904), sometimes called specialist or ‘ES - Electrical Specialist’ licences, and the 2025 Electrical Safety Rules give the full class descriptions as ‘automatic gas or oil heating, including geo-thermal, ground source heat pumps’ and ‘refrigeration or air conditioning, air to air heat pumps.’ On the FUEL side, what people call a ‘gas licence’ or ‘propane licence’ is a Certificate of Fitness issued by the Division - Natural Gas Installer, Liquefied Propane (LP) Gas Installer, or Both - and the oil equivalent is the Oil Burning Equipment Installer certificate (or the Limited version), sometimes referred to by its programme abbreviation TQP. On the HYDRONIC side, a ‘boiler licence’ or ‘heating licence’ usually means the plumbing specialist class ‘P2 - Heating System Specialist,’ which is issued by the Plumber’s Examining Board and often held as a combined P1/P2 with the Water Heater Specialist class. Separately, ‘contractor licence’ in Vermont means the Office of Professional Regulation’s RESIDENTIAL CONTRACTOR REGISTRATION - and it is a registration, not a competency licence: the statute says the system ‘is not intended to establish standards for professional qualifications or workmanship.’ Finally, EPA Section 608 refrigerant certification is a FEDERAL credential held by the individual technician; it is neither issued by Vermont nor a substitute for any Vermont licence or certificate of fitness.

License types & fees

Type	Experience	Exam	Fee
Type-S Journeyman Electrician, specialty class C3 - Refrigeration or air conditioning, air to air heat pumps (the closest thing Vermont has to an AC/refrigeration licence)	An individual licence, carried as a wallet-size card while working. To be eligible an applicant shall '(1) complete an accredited training and experience program recognized by the Board; or (2) have had training and experience, within or without this State, acceptable to the Board; and (3) pass an examination to the satisfaction of the Board in one or more of the following fields,' of which subdivision (C) is 'refrigeration or air conditioning' (26 V.S.A. 904(a)). The 2025 Vermont Electrical Safety Rules restate the class as 'C3 Refrigeration or air conditioning, air to air heat pumps' (Section 3.3(a)(3)). The Division's electricians licence application (2026 JUNE edition) states the documentation route: 'Submit proof of completion of recognized training program PLUS one year (2,000 hrs) experience through signed affidavits for each specialty applying for.' Scope is bounded: a Type-S Journeyman Electrician 'is entitled to design, install, repair, maintain and replace electrical installations as an employee or an independent contractor only in connection with the specialty field designated on the person's license, and may only install branch circuits from the existing electrical service' (Electrical Safety Rules 3.3(c)). The holder may employ other licensed persons and supervise an apprentice or electrician's helper, and for an apprentice or helper 'supervise' means the Type-S journeyman is physically present on the work site and immediately available.	A board examination in the specialty field. The Electrical Safety Rules note the current examination fee as '$80 for the standard test, or $80 for the computer-based test, paid directly to the contracted testing agency ProV' (Section 3.4(a)). Examinations may be conducted in writing or computer based and include a practical skills examination covering theoretical and practical aspects of electrical work together with pertinent laws and rules (3.4(b)). Board approval to take the examination is valid for three years (3.4(d)). An applicant who fails may retake the exam two more times on payment of the required fees; after a third failure the applicant must reapply with a new application, additional fees and board approval, and the board requires a minimum of 8 hours of education on the National Electrical Code, National Fire Alarm Code or an exam prep course before retaking (3.4(e)).	$115.00 per specialty field for a three-year licence, initial and renewal alike - 'for a type-S journeyman's license (initial and renewal) per field $115.00' (26 V.S.A. 905(d)(1)(C)); the Division's own electricians application states 'Specialist- $115.00 (per field) 3 year license fee.' A certificate suitable for framing is $10.00, a lapsed licence renewed within one year costs $25.00 on top of the renewal fee, and replacing a lost or damaged licence is $20.00 (26 V.S.A. 905(d)(2), (e), (f)). Application fees are waived on request for qualified military members and military spouses under qualifications and procedures determined by the Commissioner (26 V.S.A. 905(g)).
Type-S Journeyman Electrician, specialty class A1 - Automatic gas or oil heating, including geo-thermal, ground source heat pumps	The companion specialty for heating work, on the same statutory footing: 26 V.S.A. 904(a)(3)(A) lists 'automatic gas or oil heating' among the fields, and the 2025 Vermont Electrical Safety Rules class it as 'A1 Automatic gas or oil heating, including geo-thermal, ground source heat pumps' (Section 3.3(a)(3)). Same eligibility route - an accredited training and experience program recognised by the Board, or training and experience acceptable to the Board, plus the examination - and the same documentation the Division asks for on the application: proof of completion of a recognised training program plus one year (2,000 hours) of experience by signed affidavit for each specialty applied for. Same scope limit: only the designated specialty field, and only branch circuits from the existing electrical service (Rules 3.3(c)). Note that A1 covers the ELECTRICAL side of gas and oil heating work; the fuel side is separately certified (see the certificate of fitness entries below).	Board examination in the specialty field; ProV administers, currently $80 (Electrical Safety Rules 3.4(a)).	$115.00 per field for a three-year licence, initial and renewal (26 V.S.A. 905(d)(1)(C)). A technician licensed in both A1 and C3 pays the per-field fee for each.
Master Electrician / Journeyman Electrician (the full electrical licences a mechanical contractor may hold instead of specialty classes)	A master electrician must have been licensed as a journeyman electrician under chapter 15 for at least two years, or have had comparable experience and training within or outside Vermont acceptable to the Board, and pass an examination to the satisfaction of the Board (26 V.S.A. 902(a)); the 2025 Electrical Safety Rules state the first route slightly more tightly, as having 'been licensed as, and working as, a journeyman electrician under this chapter for at least two years' (Rules 3.1(a)(1)). A master 'is entitled to design, install, repair, maintain and replace electrical installations INCLUDING WORK IN THE SPECIALTY FIELDS designated in Section 3.3 of these rules' (Rules 3.1(c)) - so a master electrician's licence subsumes A1 and C3. A journeyman electrician must provide verification by the Vermont Apprenticeship Council of completion of an apprenticeship in electrical wiring that included both instruction and practice in work processes, or have had equivalent training and experience within or outside Vermont acceptable to the Board, and pass an examination (26 V.S.A. 903(a); the Rules render the second route as 'equivalent training acceptable to the board', Rules 3.2(a)(2)); a journeyman performs electrical installations under the direction of a master electrician or a Type-S journeyman in connection with that specialty field.	Board examination; the master electrician's examination 'shall contain questions on all specialty fields designated for type-S journeyman electricians' (Electrical Safety Rules 3.4(b)). ProV administers, currently $80.	Master $150.00 and journeyman $115.00, each a three-year fee covering both initial licence and renewal (26 V.S.A. 905(d)(1)(A)-(B)); the Division's electricians application states the same amounts.
Certificate of Fitness - Gas (Natural Gas Installer, Liquefied Propane (LP) Gas Installer, or Both) - required for gas heating work	Issued by the Division of Fire Safety, not by a licensing board. The Division states that 'all individuals engaged in the inspection, installation, and service of Propane (LP) or Natural Gas systems must be certified as required under the Vermont Fire and Building Safety Code.' Qualification is by completed industry training rather than a state examination. Natural Gas Installer, covering 'the installation, inspection and service of natural fuel gas systems': successful completion of the American Gas Association (AGA) course of study including the Fundamentals of Combustion, Gas Appliance Venting, Electricity, Gas Controls and Gas Appliances. Liquefied Propane (LP) Gas Installer, covering installation, inspection and service: successful completion of National Propane Gas Association Certified Employee Training Program (CETP) sections 1.0, 4.1, 4.2, 4.3, 4.4. Both Natural and LP Gas Installer, covering 'the installation, inspection and service of natural fuel gas and LP gas systems and equipment': the AGA course of study plus CETP books 1.0, 4.1 and 4.2. A separate Liquefied Propane (LP) Delivery Driver certification covers connection of a disconnected line, testing, appliance pilot lighting, and delivery and transfer of product, and requires CETP sections 1.0 and 2.2/2.4 as required. The Division is transitioning from CETP to the Propane Education & Research Council's PEP program: existing CETP certificates 'will be given credit and carried forward,' PEP training is accepted where certificates of completion show full completion of each required module, and a combination of CETP and PEP records may be submitted for evaluation. The Division's current gas application lists PEP paths including Delivery of LP Gas, LP Gas Tech (installation, inspection and service), Plant Operations LP Gas, and 'HVAC Tech- Limited Interior.'	No state examination is published for the gas certificate of fitness; qualification is documented completion of the AGA course of study and/or the CETP or PEP modules for the category sought, submitted with the application.	$60.00. The statute sets 'three-year initial certificate of fitness and renewal fees' and lists 'Gas appliance installation, inspection, and service: $60.00' (20 V.S.A. 2731(c)(4)(C)); the Division's Certificate of Fitness Propane (LP) / Gas Application (2025 JAN edition) states 'Initial Application $60.00' and 'Renewal Application $60.00' - the two agree.
Certificate of Fitness - Oil Burning Equipment Installer, and Oil Burning Equipment Installer (Limited)	Also issued by the Division of Fire Safety. The Division states that 'a Certification of Fitness (TQP) is required for all individuals performing activities related to fire or life safety' in oil burner work, based on published qualifications. Oil Burning Equipment Installer, covering 'the installation, inspection and service of oil burning equipment': successful completion of the examination for the Silver Certificate from the National Oil Heat Research Alliance (NORA). Oil Burning Equipment Installer (Limited), covering 'the limited installation, inspection and service of oil burning equipment': successful completion of the examination for the NORA Bronze Certificate. The Division publishes the codes it enforces for this program, which include NFPA 31 (Installation of Oil-Burning Equipment), NFPA 90A (Installation of Air-Conditioning and Ventilating Systems) and NFPA 90B (Installation of Warm Air Heating and Air Conditioning Systems), each at the current Vermont adopted edition. The Division names five training organisations for this program: Carlin Combustion Technology (Carlin University Training), Local 693 Training Center, System 2000 Energy Kinetics, the Vermont Fuel Dealers Association, and VLPA.	The NORA Silver certificate examination for the full certification, or the NORA Bronze certificate examination for the limited certification - taken through NORA, not through a Vermont board.	$60.00 for either, as a three-year initial certificate of fitness and renewal fee: 'Oil burning equipment installation, inspection, and service: $60.00' (20 V.S.A. 2731(c)(4)(D)) and 'Limited oil burning equipment installation, inspection, and service: $60.00' (20 V.S.A. 2731(c)(4)(F)).
Plumbing Specialist licence, class P2 - Heating System Specialist (hydronic space heating)	An individual licence issued by the Plumber's Examining Board through the Division of Fire Safety, carried as a wallet-sized card 'at all times while performing the licensee's specialty' and displayed on request (26 V.S.A. 2192a(a)). The P2 field is defined as 'Installation, replacement, and repair of residential, industrial, or commercial hydronic space heating systems, including radiant, solar, and other types of hydronic system design. Any work on steam systems shall be limited to steam systems with operating pressure not to exceed 15 PSIG' (26 V.S.A. 2192a(b)(2)). Eligibility is by application documenting successful completion of instruction, training and experience in or out of the State acceptable to the Board, plus an examination fee and the examination (2192a(a)). The Division's plumbers licence application states the two documented routes for P1 and P2: be a registered apprentice with the Vermont State Apprenticeship Council and provide documentation of 2,000 hours of experience covered by a completion certificate from the Vermont Department of Labor; OR document 4,000 on-the-job training hours by affidavits from a P1 or P2 licensed Specialist or a licensed Master Plumber, together with formal instruction greater than or equal to 144 hours (one year of school). Scope is bounded the same way as the electrical specialty: 'A person duly licensed as a specialist under this section may perform specialty work, either as an employee or as an independent contractor only in connection with the specialty field designated on the person's license,' a specialist may make a supply connection to an existing water supply for test and related system operation, 'but at no time shall any specialist perform any plumbing or heating work that is not specified or permitted under the specialist's license,' and 'a specialty business may hire or employ only people licensed in the specialty of the business' (2192a(c)-(d)). A specialist licence 'does not take the place of any other license required by law' (2192a(a)). Master and journeyman plumbers are exempt from paying licence or renewal fees as specialists (26 V.S.A. 2193(d)), and a journeyman plumber installs 'plumbing and water treatment or heating specialties under the direction of a master plumber' (26 V.S.A. 2172(3)).	A board examination, in whole or in part in writing, covering the theoretical and practical nature of plumbing or specialties and knowledge of State laws, the rules of the Departments of Health and of Environmental Conservation, and other rules the Board determines necessary; examinations must be relevant to the instructional material taught in classes, codes used, and new developments and procedures within the trade (26 V.S.A. 2193(a)(2)). The examination fee is determined by the Board based on the costs associated with administering the examination and, where an outside testing service conducts the examination, may be paid directly to that service (2192a(a); 2193(a)(1)). An applicant who fails may retake the examination on payment of the examination fee (2193(b)). The Division points plumbing candidates to the International Code Council for testing information and publishes a PROV bulletin for online testing.	$50.00 for the specialist licence and $50.00 for the specialist renewal (26 V.S.A. 2193(c)(3), (6)); the Division's plumbers licence application states 'Limited Licensure; Specialists (P1 and P2) - Application Fee - $50.00 per Specialty Field' and notes that a combined P1/P2 licence covers two specialty fields and therefore carries two specialty field licence fees (2025 Vermont Plumbing Rules). For comparison on the same fee schedule: master plumber $120.00 and journeyman plumber $90.00, initial and renewal alike, with a $10.00 licence certificate. Reinstatement within 90 days of expiration costs $15.00 in addition to the renewal fee (26 V.S.A. 2195(b)).
Residential Contractor registration (Office of Professional Regulation) - required above $10,000, not an HVAC competency licence	Separate from every Division of Fire Safety credential and administered by the Secretary of State's Office of Professional Regulation. 'A person shall register with the Office of Professional Regulation prior to contracting with a homeowner to perform residential construction in exchange for consideration of more than $10,000.00, including labor and materials' (26 V.S.A. 5501(a)), and 'residential construction' expressly 'includes interior and exterior construction, renovation, and repair; painting; paving; roofing; weatherization; INSTALLATION OR REPAIR OF HEATING, plumbing, solar, electrical, water, or wastewater systems' in a residential dwelling unit or a building or premises with four or fewer residential dwelling units (5501(b)). OPR states that registration for residential contractors has been required as of April 1, 2023. The registration is deliberately NOT a competency credential: 'The system of mandatory registration established by this chapter is intended to protect against fraud, deception, breach of contract, and violations of law but is not intended to establish standards for professional qualifications or workmanship that is otherwise lawful' (26 V.S.A. 5503(a)(1)). A registrant must maintain minimum liability insurance of $1,000,000.00 per occurrence and $2,000,000.00 aggregate, evidence of which may be required as a precondition to issuance or renewal, and must execute a written contract before receiving a deposit or commencing work where the estimated value of labour and materials exceeds $10,000.00, specifying price, estimated start and completion dates, scope of work and a change-order provision (26 V.S.A. 5509).	None. Eligibility is compliance with the chapter and applicable State law and satisfaction of any judgment order related to the provision of professional services to a homeowner (26 V.S.A. 5508).	Paid at initial application and biennial renewal: registration, individual $75.00; registration, business organization $250.00; State certifications $75.00 for a first certification and $25.00 for each additional certification (26 V.S.A. 5507).

Who does NOT need this license — exemptions

Vermont has no single HVAC exemption list, because it has no single HVAC licence - the carve-outs sit in four separate places, and each one exempts only its own credential. Reading one and assuming it covers the rest is the classic Vermont mistake.

ELECTRICAL - 26 V.S.A. 910 (‘License not required’). ‘A license shall not be required for the following types of work: (1) Any electrical work, including construction, installation, operation, maintenance, and repair of electrical installations in, on, or about equipment or premises, that are owned or leased by the operator of any industrial or manufacturing plant, if the work is done under the supervision of an electrical engineer or master electrician in the employ of the operator. (2) Installation in laboratories of exposed electrical wiring for experimental purposes only. (3) Any electrical work by an owner or his or her regular employees in the owner’s freestanding single unit residence, in outbuildings accessory to such freestanding single unit residence, or any structure on owner-occupied farms. (4) Electrical installations performed as a part of a training project of a vocational school or other educational institution. However, the installation shall be inspected if the building in which the installation is made is to be used as a “complex structure”. (5) Electrical work performed by an electrician’s helper under the direct supervision of a person who holds an appropriate license issued under this chapter. (6) Any electrical work in a building used for dwelling or residential purposes that contains no more than two dwelling units. (7) Installation of solar electric modules and racking on complex structures to the point of connection to field-fabricated wiring and erection of net metered wind turbines.’ Subdivision (6) is the one that governs most residential HVAC electrical work. The 2025 Vermont Electrical Safety Rules restate the boundary from the other direction: ‘With limited exceptions, anyone performing electrical work in the State of Vermont, other than in a residential building containing two or fewer dwelling units or electrical work regulated under the National Electrical Code, article 800, Communications Circuits, is required to be licensed as an electrician.’

ELECTRICAL, CHAPTER-LEVEL - 26 V.S.A. 882 (‘Exceptions’). Chapter 15 as a whole ‘does not apply to: (1) The construction, installation, operation, repair, or maintenance of electrical installations that are used by a public utility in rendering its authorized service; nor to the installation, operation, repair, and wiring associated with telecommunication services and equipment used for the transmission of information by electricity regardless of the location of such electrical installations, equipment, or facilities. (2) Electrical installations in ships, pipeline systems, railway rolling stock, automotive equipment, or portable sound equipment. (3) The manufacture, testing, or repair of electrical equipment in the plant of the manufacturer of the equipment. (4) The construction, repairs, or maintenance of buildings used exclusively for agricultural purposes on owner-occupied farms.’ The penalty section confirms both lists are operative: a person who installs, replaces or repairs any electrical installation ’except as provided in sections 882 and 910 of this title’ without an appropriate licence is subject to a fine of not more than $500.00 for each offence (26 V.S.A. 911).

PLUMBING AND HEATING SPECIALTIES - 26 V.S.A. 2198 (‘Exceptions; license not required’). ‘All plumbing and specialty work performed in Vermont shall be performed by persons licensed under this chapter except that a license shall not be required for the following types of work: (1) Any plumbing and specialty work performed by an owner or the owner’s regular employees in the owner-occupied, freestanding single family dwelling or in outbuildings accessory to the owner-occupied, single family dwelling. (2) Installations of plumbing systems in laboratories for experimental purposes only. (3) A person who regularly employs a maintenance person whose duties include the maintenance of plumbing on the property of that person. (4) Plumbing or specialty installations performed as part of a training project of a vocational school or other educational institution. However, the installation shall be inspected if the building is to be sold as a private dwelling or public building. (5) A person who performs miscellaneous jobs of manual labor on the person’s own property in the course of which plumbing repairs or alterations are made. (6) For the construction, repair, or maintenance of buildings used exclusively for agricultural purposes and animal housing located on owner-occupied farms. (7) Work performed by employees of any public or private water company, who in the main course of their employment install, maintain, or repair water supply pipes, meters, or control valves.’ The section does not stop there: subsection (b) provides that ‘Plumbing installed or maintained by persons included in this section shall conform to State law’ - being exempt from the licence does not exempt the work from the code. The Division adds a scope boundary of its own for the plumbing program: the rules apply to all public buildings whether or not connected to public water or sewage systems and to all other buildings or facilities connected to a public water or sewage system, and on coverage of owner-occupied homes the Division’s plumbing PAGE and the current rules conflict, and the dated rules control: the page still says owner-occupied single-family residences not on public water or sewage systems ‘are not covered by these rules’, but the 2025 Vermont Plumbing Rules (effective 11/04/2025), Section 2 (Scope), state ‘These rules shall apply to all public buildings, whether or not they are connected to a public water system or a public sewerage system’, that ‘This includes owner-occupied single-family residences’, and that owner-occupied single-family residences which are not connected ‘do not require a work notice’ - so the rules DO cover owner-occupied homes; what an off-system owner-occupied residence is excused from is the work notice, not the rules. Note also that the plumbing statute’s scope reaches specialty work, so the P2 heating specialist carve-outs are these same seven and no others.

GAS AND OIL CERTIFICATES OF FITNESS - no exemption list is published. The Division states without qualification that ‘all individuals engaged in the inspection, installation, and service of Propane (LP) or Natural Gas systems must be certified as required under the Vermont Fire and Building Safety Code,’ and that for oil burner work ‘a Certification of Fitness (TQP) is required for all individuals performing activities related to fire or life safety.’ The statute behind the program allows the Commissioner to grant variances or exemptions from rules adopted under the subchapter where strict compliance would entail practical difficulty, unnecessary hardship, or is otherwise found unwarranted, provided the variance or exemption secures the public safety and health and the petitioner demonstrates methods, means or practices that in the Commissioner’s opinion provide equal protection - but that is a case-by-case petition, not a standing exemption, and it expressly excludes the energy goals education module (20 V.S.A. 2731(e)).

RESIDENTIAL CONTRACTOR REGISTRATION - 26 V.S.A. 5502 (‘Exemptions’). ‘This chapter does not apply to: (1) an employee acting within the scope of his or her employment for a business organization registered under this chapter; (2)(A) a professional engineer, licensed architect, or a tradesperson licensed, registered, or certified by the Department of Public Safety acting within the scope of his or her license, registration, or certification; or (B) a business that performs residential construction if the work is performed primarily by or under the direct supervision of one or more employees who are individually exempt from registration under subdivision (2)(A) of this section; (3) delivery or installation of consumer appliances, audio-visual equipment, telephone equipment, or computer network equipment; (4) landscaping; (5) work on a structure that is not attached to a residential building; or (6) work that would otherwise require registration that a person performs in response to an emergency, provided the person applies for registration within a reasonable time after performing the work.’ Subdivision (2)(A) is the HVAC-relevant one: Division of Fire Safety credentials are Department of Public Safety credentials, so a technician working within the scope of an electrical, plumbing, gas or oil credential is outside the registration requirement - but only within that scope.

And one thing no Vermont exemption reaches: EPA Section 608 refrigerant certification is a federal requirement under the Clean Air Act and 40 CFR part 82, subpart F, and applies to anyone who maintains, services, repairs or disposes of equipment that could release refrigerant, everywhere in the state.

Fees

Every fee below is set in Vermont statute, and in each case the Division of Fire Safety’s own live application form states the same amount - the two were compared and agree. ELECTRICAL, three-year licence fees identical for initial and renewal (26 V.S.A. 905(d)(1)): master electrician $150.00; journeyman electrician $115.00; Type-S journeyman electrician $115.00 PER FIELD, so a technician holding both A1 and C3 pays $115.00 for each. The Division’s electricians licence application (2026 JUNE edition) states ‘Master- $150.00 3 year license fee’, ‘Journeyman - $115.00 3 year license fee’ and ‘Specialist- $115.00 (per field) 3 year license fee’, and notes that examination fees are not included in the application. Add-ons: certificate suitable for framing $10.00; a lapsed licence renewed within one year of expiration costs $25.00 in addition to the renewal fee; replacement of a lost or damaged licence $20.00 (26 V.S.A. 905(d)(2), (e), (f)). The electrical examination fee is currently $80, paid directly to ProV. PLUMBING, two-year licence and renewal fees (26 V.S.A. 2193(c)): specialist licence $50.00 and specialist renewal $50.00 - per specialty field, so a combined P1/P2 licence carries two specialty field fees; master plumber $120.00; journeyman plumber $90.00; licence certificate $10.00. Reinstatement within 90 days of expiration adds $15.00 to the renewal fee (26 V.S.A. 2195(b)). Master and journeyman plumbers are exempt from paying licence or renewal fees as specialists (2193(d)). GAS AND OIL CERTIFICATES OF FITNESS, three-year initial and renewal (20 V.S.A. 2731(c)(4)): gas appliance installation, inspection and service $60.00; oil burning equipment installation, inspection and service $60.00; limited oil burning equipment installation, inspection and service $60.00. The Division’s Certificate of Fitness Propane (LP) / Gas Application (2025 JAN edition) confirms $60.00 initial and $60.00 renewal. RESIDENTIAL CONTRACTOR REGISTRATION at OPR, paid at initial application and biennial renewal (26 V.S.A. 5507): individual $75.00; business organization $250.00; State certifications $75.00 for a first and $25.00 for each additional. Fee waivers: the electrical and plumbing boards shall, upon request, waive application fees for qualified military members and military spouses pursuant to qualifications and procedures determined by the Commissioner (26 V.S.A. 905(g), 2193(e)). Payment practicalities from the Division’s own forms: applications are mailed with payment, checks made out to Division of Fire Safety - electrical and plumbing to the Central Office, Licensing Division, 45 State Drive, Waterbury, VT 05671-8200; gas and oil to the Department of Public Safety, 100 Mineral Street Suite 307, Springfield, VT 05156. Some applications and renewals can be done through the Division’s licensing web portal. Electrical and plumbing applications must be signed and notarised, and the Division reviews them two weeks before the board meeting date.

Exam

Vermont examines by credential, not by trade, so an HVAC technician’s testing burden depends on which credentials the work requires. ELECTRICAL: to be eligible for a Type-S journeyman licence in class C3 (refrigeration or air conditioning, air to air heat pumps) or class A1 (automatic gas or oil heating, including geo-thermal and ground source heat pumps), an applicant must complete an accredited training and experience program recognised by the Board, or have training and experience acceptable to the Board, and ‘pass an examination to the satisfaction of the Board’ in one or more specialty fields (26 V.S.A. 904(a)). Examinations may be conducted in writing or computer based and include a practical skills examination covering theoretical and practical aspects of electrical work together with pertinent laws and rules; the master electrician’s examination additionally contains questions on all specialty fields designated for Type-S journeyman electricians (2025 Vermont Electrical Safety Rules 3.4(b)); the statute’s own wording is narrower - 26 V.S.A. 905(b) says the master’s examination ‘shall contain questions on the installation of lightning rods, fire alarms, and fire detection systems’ - and both are stated because they differ. The examination fee is set by the Board but may be no greater than the cost of administering the examination and may be paid directly to the testing agency; the Rules note the current fee as ‘$80 for the standard test, or $80 for the computer-based test, paid directly to the contracted testing agency ProV’ (Rules 3.4(a); 26 V.S.A. 905(a)). Board approval to test is valid for three years (Rules 3.4(d)). A failed examination may be retaken twice more on payment of the required fees; after a third failure the applicant reapplies with a new application, additional fees and Board approval, and must first obtain a minimum of 8 hours of education on the National Electrical Code, the National Fire Alarm Code, or an exam prep course (Rules 3.4(e)). The Rules also note that the electrical examinations are now on the 2023 NEC. PLUMBING: a P2 Heating System Specialist takes a Board examination, in whole or in part in writing, on the theoretical and practical nature of plumbing or specialties and on State laws and the rules of the Departments of Health and of Environmental Conservation; the examination fee is determined by the Board based on administration cost and may be paid directly to an outside testing service, and a failed examination may be retaken on payment of that fee (26 V.S.A. 2193(a)-(b), 2192a(a)). The Division directs plumbing candidates to the International Code Council for testing information and publishes a PROV bulletin covering online testing. GAS AND OIL CERTIFICATES OF FITNESS: no Vermont state examination is published. Gas certification is granted on documented completion of the AGA course of study and/or National Propane Gas Association CETP sections (transitioning to PEP modules); oil certification is granted on successful completion of the NORA examination for the Silver Certificate (full) or the Bronze Certificate (limited) - those examinations are administered by NORA, not by Vermont.

Renewal & continuing education

Vermont runs three different clocks, and an HVAC technician holding credentials from more than one program will have more than one renewal date. ELECTRICAL - ‘All licenses expire on the last day of a month designated by the Board. A license shall be valid for three years’ (26 V.S.A. 908(a); 2025 Electrical Safety Rules 3.5(a)). A renewal notice and application are sent before expiration, and the signed renewal application, the certification of continuing education and the fee must be returned before the licence expires; the Board renews on receipt of the renewal application, certification of continuing education, child support certification, tax certification and the required fee on or before the expiration date. If a licence is allowed to lapse it may be renewed within one year of its expiration date by paying $25.00 in addition to the renewal fee (26 V.S.A. 905(e); Rules 3.5(c)). PLUMBING - ‘All licenses expire on the last day of a month designated by the Board. A license shall be valid for two years’ (26 V.S.A. 2195(a)). A licensee who fails to renew before expiration may reinstate within 90 days by paying a $15.00 reinstatement fee in addition to the renewal fee; a licensee who fails to renew within 90 days of expiration ‘shall appear before the Board to request reinstatement’ (2195(b)-(c)). GAS AND OIL CERTIFICATES OF FITNESS - the statute sets ’three-year initial certificate of fitness and renewal fees,’ so these run on a three-year cycle (20 V.S.A. 2731(c)(4)). RESIDENTIAL CONTRACTOR REGISTRATION - fees are paid ‘at initial application and biennial renewal,’ a two-year cycle (26 V.S.A. 5507). Across every one of these, the Vermont Energy Goals education module is a condition of renewal as well as of initial issuance (26 V.S.A. 905(h), 2193(f); 20 V.S.A. 2731(a)(2)). ELECTRICAL (36-month lookback, tied to the three-year licence): ‘All journeyman and master electricians shall, as a condition of license renewal, complete 15 hours of instruction, approved by the Board, on the national electrical code during the preceding 36-month period. All holders of a type-S journeyman license shall, as a condition of renewal, complete eight hours of instruction, approved by the Board, on the subject of the license holder’s specialty during the preceding 36 months, except that holders of multiple type-S licenses shall not be required to complete more than 15 hours of instruction during the preceding 36 months’ (26 V.S.A. 908(b)). The 2025 Vermont Electrical Safety Rules add a carve-out that matters to HVAC technicians specifically: ‘A person who is licensed in more than two fields of specialized competence shall not be required to complete more than a total of 15 hours of instruction. Exception: A person licensed only as a Type S A1 and C3 shall not be required to complete more than 8 hours of continuing education’ (Rules 3.5(b)). So a technician holding exactly the heating and the refrigeration/AC specialties - the common HVAC pairing - owes 8 hours per cycle, not 16. PLUMBING (24-month lookback, tied to the two-year licence): ‘applicants for license renewal shall provide to the Board evidence of completion of eight hours of continued training or instruction, approved by the Board, within the previous 24-month period’ (26 V.S.A. 2195(d)). GAS CERTIFICATES OF FITNESS: the Division requires, for each of the Natural Gas Installer, LP Gas Installer and Both categories, ’eight (8) hours of related instruction during the previous 3 years including at least two hours regarding the prevention of CO leakage and the procedure for safety inspection of an existing appliance - NFPA 54 (annex H).’ OIL CERTIFICATES OF FITNESS: for both the full and the limited Oil Burning Equipment Installer certifications, ’eight (8) hours of related instruction during the previous three (3) years including at least two hours regarding prevention of CO leakage and the procedure for inspection, or a current silver or gold certificate from NORA.’ ON TOP OF ALL OF THESE: the Vermont Energy Goals education module, not more than two hours, is required as a condition of both initial licensure and renewal for electricians, plumbers, and gas and oil certificants (26 V.S.A. 905(h), 2193(f); 20 V.S.A. 2731(a)(2)); master and journeyman plumbers who complete it need not repeat it for an additional specialty licence. The Division maintains a master list of approved continuing education providers and separate lists of approved electrical and plumbing continuing education seminars.

Frequently asked questions

Does Vermont require an HVAC licence?

Not under that name - Vermont issues no HVAC, air conditioning, refrigeration or mechanical-contractor licence. The Secretary of State’s Office of Professional Regulation publishes what it calls a comprehensive list of the professions it regulates, and no HVAC or mechanical trade appears on it; the Division of Fire Safety publishes the full ledger of trade credentials it issues, and there is no HVAC line there either. Instead Vermont regulates the pieces of HVAC work. The electrical side is covered by Type-S journeyman specialty classes A1 (automatic gas or oil heating, including geo-thermal and ground source heat pumps) and C3 (refrigeration or air conditioning, air to air heat pumps). Gas work needs a Division certificate of fitness; oil-fired heating needs the oil-burning equipment certificate. Hydronic space heating needs the P2 Heating System Specialist plumbing licence. And contracting with a homeowner for more than $10,000 needs residential contractor registration with OPR.

What are the A1 and C3 licences, and who issues them?

They are the two Type-S journeyman electrician specialty classes that cover HVAC work, issued by the Electricians’ Licensing Board through the Division of Fire Safety under 26 V.S.A. chapter 15. The Division’s own ledger names them ‘A1 - Automatic Gas / Oil Heating’ and ‘C3 - Refrigeration and Air Conditioning’; the 2025 Vermont Electrical Safety Rules spell them out as ‘A1 Automatic gas or oil heating, including geo-thermal, ground source heat pumps’ and ‘C3 Refrigeration or air conditioning, air to air heat pumps.’ Each is an individual licence carried as a wallet card. To qualify you complete an accredited training and experience program recognised by the Board (or training and experience the Board accepts) and pass a Board examination in the field; the Division’s application also asks for one year - 2,000 hours - of experience by signed affidavit for each specialty. A Type-S holder may work only in the designated specialty field and may only install branch circuits from the existing electrical service. A master electrician’s licence covers all the specialty fields.

Do I need an electrical licence to install a furnace or air conditioner in a Vermont home?

For the electrical work in a single-family home or a duplex, no. Vermont requires no electrical licence for ‘any electrical work in a building used for dwelling or residential purposes that contains no more than two dwelling units’ (26 V.S.A. 910(6)), and the 2025 Vermont Electrical Safety Rules restate the same line. The moment the building has three or more dwelling units, or is commercial or industrial, the A1 or C3 specialty licence (or a full journeyman or master electrician licence) applies. Be careful not to read that exemption too broadly: it covers only the electrical licence. Gas piping and gas appliance work still requires the Division’s gas certificate of fitness, oil-burning equipment work still requires the oil certificate, hydronic heating still requires the P2 specialist licence, and a homeowner contract over $10,000 still requires residential contractor registration.

What does a Vermont HVAC credential cost?

Each amount below is set in statute and matches the Division of Fire Safety’s own application forms. Type-S journeyman specialty licence (A1 or C3): $115.00 per field for a three-year term, initial and renewal alike - so holding both A1 and C3 costs $115.00 each. Full electrical licences: journeyman $115.00, master $150.00, also three-year. The electrical examination is currently $80, paid directly to ProV. Gas certificate of fitness: $60.00 initial and $60.00 renewal, three-year. Oil-burning equipment certificate of fitness, full or limited: $60.00, three-year. P2 Heating System Specialist plumbing licence: $50.00 per specialty field, two-year, with the same $50.00 at renewal - master and journeyman plumbers pay no specialist fee. Residential contractor registration with OPR: $75.00 for an individual or $250.00 for a business organization, biennially. Application fees are waived on request for qualified military members and military spouses on the electrical and plumbing sides.

How much continuing education does Vermont require?

It depends on the credential, and there is a favourable rule for HVAC technicians specifically. Type-S journeyman electricians complete eight hours of Board-approved instruction on their specialty during the preceding 36 months; holders of multiple Type-S licences are capped at 15 hours, and the 2025 Electrical Safety Rules add that ‘a person licensed only as a Type S A1 and C3 shall not be required to complete more than 8 hours of continuing education’ - so the common heating-plus-cooling pairing owes 8 hours, not 16. Master and journeyman electricians complete 15 hours on the National Electrical Code per 36 months. Plumbing licensees show eight hours of Board-approved training within the previous 24 months. Gas and oil certificate holders need eight hours of related instruction during the previous three years, including at least two hours on preventing carbon monoxide leakage and on safety inspection of an existing appliance. On top of all of these, every applicant and renewing licensee must complete the Vermont Energy Goals education module of not more than two hours.

Do I need to register as a residential contractor to do HVAC work in Vermont?

Possibly not, and the exemption is the reason. Registration with the Office of Professional Regulation is required before contracting with a homeowner for residential construction worth more than $10,000 including labour and materials, and ‘residential construction’ expressly includes installation or repair of heating systems (26 V.S.A. 5501). But the chapter does not apply to ‘a professional engineer, licensed architect, or a tradesperson licensed, registered, or certified by the Department of Public Safety acting within the scope of his or her license, registration, or certification,’ nor to a business whose residential construction is performed primarily by or under the direct supervision of such tradespeople (26 V.S.A. 5502(2)). Division of Fire Safety credentials are Department of Public Safety credentials, so a technician working within the scope of an electrical, plumbing, gas or oil credential falls inside that carve-out - and an employee of a registered business organization is exempt as well. Where registration does apply, it brings $1,000,000 per occurrence and $2,000,000 aggregate liability insurance and a written contract with specified price, dates, scope and change-order terms.
