Checking an HVAC company in the Burlington area
HVAC licenses in Vermont
Licensing is split between the state and local governments.
Who licenses: Vermont Department of Public Safety, Division of Fire Safety (trade licensing and certification)
License types: Oil Burning Equipment Installer, Oil Burning Equipment Installer (Limited), Natural Gas Installer, Liquefied Propane (LP) Gas Installer, Both Natural and LP Gas Installer, Refrigeration and Air Conditioning (C3 license code), Automatic Gas / Oil Heating (A1 license code).
Companies: We found no single statewide HVAC contractor license in Vermont; instead the Division of Fire Safety certifies individuals who install or service oil-burning equipment, natural gas or propane systems, and lists refrigeration/air conditioning and gas/oil heating among its trade license categories, but we could not confirm the statute or which of these apply to a given HVAC job.
Local rules: The oil burner certification list is at the lookup URL, the gas installer list is at https://data.vermont.gov/Government/Gas-Certifications/6n8x-pr2k/data, and the Division says to call 802-479-7564 for other license verification; We did not read the statute so confidence is medium.
Check a license: data.vermont.gov
Ask the technician for their Vermont Division of Fire Safety certification or license number and check it against the state's published oil and gas certification lists or by calling the Division.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
We could not confirm every detail from Vermont’s own sources, so treat this as a starting point and check with the agency.
Sources: firesafety.vermont.gov, firesafety.vermont.gov, firesafety.vermont.gov, firesafety.vermont.gov. Checked October 2026 from official sources. This is not legal advice.
Questions to ask
Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
Seasonal care
Getting through a Burlington winter
Heating season is the long one in Burlington, so the furnace, boiler or heat pump does most of the work. Start with these before the first cold snap – and keep carbon monoxide alarms working.
