Virginia licenses HVAC twice over: the individual mechanic needs a DPOR tradesman license (§ 54.1-1129), and the business needs a Class A, B, or C contractor license with the HVA classification, qualified by someone holding a Master HVAC license.
Two traps set Virginia apart. The HVA classification expressly excludes gas piping, so hooking up a gas furnace takes a gas-fitting designation on top of HVAC. And since April 1, 2025 there is a residential HVAC license — dwellings and townhouses only — reachable with as little as two years of experience plus 160 hours of training. Federally, anyone servicing refrigerant-containing equipment still needs EPA Section 608 certification.
The state sets the license floor; the county or city permit office controls filing, inspections, and local rules wherever the job site sits.
DPOR's license is statewide, but the application itself makes every firm affirm it will comply with local licensing in each city, county, and town where it works. Two local desks matter. First, the building department: Virginia's Uniform Statewide Building Code supersedes local building codes (§ 36-98) but is enforced locally (§ 36-105), and § 54.1-1111 bars the permit desk from issuing a permit without proof of a DPOR license or a written statement that you are exempt. Virginia cities are independent of counties (§ 15.2-102), so in Virginia Beach, Norfolk, Chesapeake, Richmond, or Alexandria the city's own building department is the desk — no county is involved — while in counties such as Arlington and Loudoun the county building department handles county permits. Towns sit inside their counties. Second, the commissioner of the revenue: the local business license (BPOL) is owed where your office is, and any other locality may require its own once your work there tops $25,000 in a year (§ 58.1-3715); that office also needs proof of your DPOR license or an affidavit of exemption.
The local offices section below names the exact permit desk for every Virginia 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.
The HVA classification excludes gas piping. A shop installing gas furnaces needs the gas-fitting designation on its technicians and the GFC specialty on its firm license.
The April 2025 residential HVAC license (dwellings and townhouses only) needs as little as 2 years plus 160 training hours; three years holding it qualifies you for master.
Under 2026's House Bill 30, DPOR adds a $7.25-per-year technology fee to certain fees from July 1, 2026 through June 30, 2030 — that is the $14.50 baked into each two-year application total.

Statutory consequences with their citations — not estimates, not “commonly cited” guesses.
Practicing as an HVAC tradesman or gas fitter without a DPOR license is a Class 1 misdemeanor.
Contracting or bidding on work for another without a license, or without the proper class for the value of the work, is a Class 1 misdemeanor — up to 12 months in jail and a $2,500 fine — plus a fine of up to $500 for every day in violation. In a consumer transaction it is also a Virginia Consumer Protection Act violation.
A construction contract entered by an unlicensed contractor is not enforceable by that contractor unless he substantially performed in good faith AND did not actually know a license was required. Letting a license lapse creates a rebuttable presumption that you knew.

Pending verification: DPOR's Tradesmen page describes continuing education per 'every 2-year term', but 18VAC50-30-120 (amended effective August 1, 2025) sets a three-year tradesman license term; this record follows the regulation · Whether the Refrigeration (REF) contractor specialty is needed in addition to HVA for any residential HVAC scope · Residential HVAC exam fee at PSI
