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]

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]

  • Minimum age

    State law: registered apprentices must be at least 16 (unless another law sets a higher age). UA Local 693 requires 18. [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]

  • Credit for prior school or military

    Registered program standards must give advanced standing (credit) for proven skills, experience or training. The Electricians' Licensing Board may also recognize prior experience or qualifications. [1][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]

Vermont splits heating and cooling work among several credentials, all handled by the Division of Fire Safety:
