Vermont regulates HVAC by fuel and task rather than with one HVAC license. The Fire & Building Safety Code (§ 1:1.13.1) requires a certificate of fitness for anyone installing, modifying, or servicing gas- or oil-burning heating systems: LP gas (CETP/PEP training), natural gas (AGA course), both, a limited interior LP certificate for HVAC technicians, oil burning equipment (NORA Silver), and limited oil (NORA Bronze). Each costs $60 for three years (20 V.S.A. § 2731(c)(4)) and renews with 8 hours of instruction, including 2 hours on carbon monoxide, plus the Vermont Energy Goals module.
Hydronic space heating and water heaters are plumbing specialties — a $50 heating system or water heater specialist license from the Plumber's Examining Board, or a plumbing license (26 V.S.A. § 2192a). HVAC wiring outside one- and two-unit homes needs a type-S electrician license (A1 gas/oil heating and ground-source heat pumps; C3 refrigeration, AC, and air-to-air heat pumps). Refrigerant work needs federal EPA Section 608 certification. Holders of these Department of Public Safety credentials are exempt from OPR residential contractor registration within their scope (26 V.S.A. § 5502(2)).
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
Fuel-gas and oil certificates, plumbing licenses, and electrician licenses are all issued by the state through the Division of Fire Safety. Plumbing and electrical work notices and inspections come from the Division unless a town holds an assigned inspection program (26 V.S.A. §§ 898, 2174); a town plumbing program may set standards stricter than the state's only with Plumber's Examining Board approval.
The local offices section below names the exact permit desk for every Vermont county on file.
Each row names the issuing authority, cost, timeline, citation, and status behind the requirement — verified against the official source.
Published fees from the issuing authorities, as of October 2026. Local permit fees vary by project and jurisdiction — the basis is stated where a flat number does not exist.
Vermont credentials HVAC work by task — fuel gas, oil, hydronic, electrical, refrigerant — not by trade title.
Certificates rest on national programs: CETP/PEP for propane, the AGA course for natural gas, NORA Silver or Bronze for oil.
Tradespeople licensed, registered, or certified by the Department of Public Safety are exempt from OPR registration within their scope (§ 5502(2)).

Pending verification: Whether the certificate-of-fitness requirement reaches work in owner-occupied single-family homes: the Division's gas page says 'all individuals' must be certified, but 20 V.S.A. § 2730(c) limits the subchapter's rules to public buildings · Continuing education hours for plumbing heating and water heater specialists (26 V.S.A. § 2195(d) sets 8 hours per 24 months for license renewal generally) · Training and exam costs for CETP/PEP, AGA, and NORA programs
