How to get licensed for HVAC work in Vermont
State law and licensing-board sources · Last reviewed October 11, 2026
Vermont doesn't issue one "HVAC license." Instead, the Department of Public Safety's Division of Fire Safety licenses or certifies each part of the job: Type-S journeyman electrician licenses for gas and oil heating and heat pumps (A1) or refrigeration and air conditioning (C3), gas installer and oil burner certifications, and plumbing specialist licenses for hydronic heating. Anyone who services equipment that could release refrigerant also needs federal EPA Section 608 (the U.S. Environmental Protection Agency's refrigerant rule) certification. [1][2][3][4][5]
New to the trade?
Starting from zero in Vermont
Start by getting hired by a Vermont heating and cooling company, as an apprentice in a registered program or as a helper working under a licensed electrician who is on site. A short pre-apprenticeship such as ReSOURCE's HVAC 101 (heating, ventilation and air conditioning), certified by the Vermont Department of Labor, feeds into a registered HVAC Technician apprenticeship. Federal rules also require EPA Section 608 certification for anyone who services equipment that could release refrigerant. [1][5][8][10][13]
High school diploma or GED
No diploma rule was found in Vermont's electrical, plumbing or gas and oil certification requirements The state apprenticeship law lets each sponsor set minimum qualifications. UA (United Association, the plumbers' and pipefitters' union) Local 693, whose apprentices train in plumbing, pipefitting and HVAC, requires a high school diploma or GED (General Educational Development test). Certified pre-apprenticeships can, where practicable, help you earn a diploma or equivalent. [1][4][10][11][15]
Register before you start work
No state HVAC trainee card exists. In a registered apprenticeship, your sponsor files your signed apprenticeship agreement with the Vermont Department of Labor for approval. [15]
Helper jobs
For electrical work, Vermont law exempts an electrician's helper working under the direct supervision of a licensee For Type-S work, the Type-S journeyman must be physically present on site. [1][8]
EPA Section 608
Federal rules require technicians who maintain, service, repair or dispose of equipment that could release ozone-depleting refrigerants to be certified. [5]
Pay while you learn
By law, an adult registered apprentice's starting wage must be at least the minimum wage or 50% of the journey-worker rate, whichever is higher, with raises as skills grow. [15]
Still in high school?
Vermont's apprenticeship law sets up registered youth apprenticeship programs for 16- and 17-year-olds. Since July 1, 2026 (Act 107 of 2026), they're for students who haven't finished high school and are enrolled in a career technical education (CTE) program, and a regional CTE center submits the program for registration. Regional career technical education (CTE) centers run state-approved technical programs, and the Agency of Education's Fast Forward and dual enrollment programs give college credit. No rule was found that counts high school CTE hours toward a Type-S, gas or oil credential. [15][17][18][19]

No single HVAC license in Vermont
Vermont splits heating and cooling work among several credentials, all handled by the Division of Fire Safety:
- Electrical work on heating and cooling equipment needs an electrician license. The Type-S journeyman license covers one specialty: A1 is automatic gas or oil heating, including geothermal and ground-source heat pumps; C3 is refrigeration or air conditioning, including air-to-air heat pumps.
- Gas appliances: all individuals who install, inspect or service propane or natural gas systems must be certified under the Vermont Fire and Building Safety Code.
- Oil burners: a Certification of Fitness is required for oil burner installers.
- Hydronic (hot-water) heating: the plumbing law's heating system specialist license.
Licensed master electricians and master plumbers can also do the work their licenses cover. Federal EPA Section 608 certification is separate and applies nationwide. [1][2][3][4][5][6]
Type-S A1 and C3 licenses
To qualify for a Type-S license, you complete an accredited training and experience program the Board recognizes (or training and experience it accepts) and pass an exam in each field. The application asks for proof of the training program plus one year (2,000 hours) of experience on signed affidavits.
Type-S holders may work only in their specialty and may only install branch circuits from the existing electrical service. The license costs $115 per field for three years. Renewal needs 8 hours of approved instruction on your specialty; someone licensed only in A1 and C3 needs no more than 8 hours in total. [1][7][8]
Gas and oil certifications
- Natural gas installer: complete the American Gas Association course of study (combustion, venting, electricity, gas controls and appliances).
- Propane (LP) gas installer: complete the required National Propane Gas Association CETP sections; the newer PERC (Propane Education & Research Council) Education Program (PEP) modules are also accepted.
- Oil burning equipment installer: pass the National Oil Heat Research Alliance (NORA) Silver certificate exam; the limited certification uses the Bronze exam.
Each needs 8 hours of related instruction every three years, including at least two hours on preventing carbon monoxide leaks, and the Vermont Energy Goals module. [2][3]
Apprenticeships and training
Employers sponsor registered apprenticeships through the Vermont Department of Labor. The Department lists ReSOURCE's HVAC 101 as a certified pre-apprenticeship that feeds VHV's registered HVAC Technician apprenticeship.
UA Local 693 in South Burlington runs a five-year apprenticeship covering plumbing, pipefitting, HVAC and welding, with free classes two nights a week. It requires age 18 and a high school diploma or GED. For more, see how to get an apprenticeship. [9][10][11]
