HVAC Journeyman License Requirements by State

A journeyman HVAC license lets a technician install, service and repair heating and cooling systems with less direct supervision than an apprentice, usually still under a licensed contractor or master. Only about two in five states plus DC issue a distinct journeyman, journeyperson or technician license to the individual; most of the other states still regulate HVAC through a state contractor's license with no separate tier below it, and a smaller group leaves HVAC licensing to the city or county entirely.

At a glance

• About 20 states plus DC issue an individual HVAC journeyman, journeyperson or technician license, separate from the business-level contractor license.
• Colorado, Illinois, Indiana, Kansas, Minnesota, Missouri, Nebraska, New York, Pennsylvania, South Dakota and Wyoming have no state HVAC license at all. Florida's journeyman license is issued by the county or city, not the state.
• Experience requirements range from 2 years (North Carolina, Alabama) to 5 years (Ohio).
• Texas and Nevada issue no individual journeyman tier; the credential sits at the registered technician level (Texas) or inside the contractor license itself (Nevada).

What "journeyman" means in HVAC licensing

A contractor license qualifies a business to sell and warranty HVAC work. A journeyman (or journeyperson) license qualifies an individual to perform that work, typically after an apprenticeship and a trade exam, and typically while still working under a master or a licensed contractor rather than running jobs independently. Our contractor license guide covers the business side; this page covers the individual technician tier by state.

The terminology varies. Maryland, New Jersey, South Carolina and others use "HVACR" to include refrigeration. Vermont and Washington fold HVAC work into an electrical specialty license. Texas uses "registered" and "certified" technician instead of journeyman. Where a state has no state level tier at all, the city or county sets its own apprentice, journeyman and master structure, and a journeyman license from one city will not automatically transfer to the next.

HVAC journeyman license by state

Notes on rows that need more than the table allows:

• Florida's journeyman license is issued by a county or municipality, never the state, but under Fla. Stat. 489.1455 any Florida local journeyman license must be honored by every other Florida county and city.
• Texas has no apprentice, journeyman or master tiers at all. TDLR registers "registered technicians" and "certified technicians," who work under a licensed air conditioning and refrigeration contractor.
• Nevada and Arizona fold journeyman level experience into the contractor license itself; neither state issues a separate journeyman credential to individuals.
• Mississippi licenses HVAC contractors through MSBOC for residential remodeling or repair jobs over $10,000, and for new residential construction or commercial jobs over $50,000; below those thresholds, and for any individual technician credential, it is set by the city.
• New Hampshire licenses gas fitters as a distinct trade. Its oil heating technician certification, covering oil burner and solid fuel equipment, is voluntary under the state's mechanical rules; general electric heat pump and air conditioning work carries no state license.
• Vermont and Washington license HVAC work as an electrical specialty (Vermont's A1 gas/oil heating and C3 refrigeration and air conditioning; Washington's 06A and 06B HVAC/R specialties), not as a separate HVAC trade.
• Ohio's Construction Industry Licensing Board license is mandatory for commercial HVAC work; residential HVAC in Ohio is set by the city, and Columbus, Cleveland and Cincinnati each run their own program.

For the full application process, fees and renewal cycle in a state we already cover in depth, see our guides to the Kentucky, Maryland, Virginia, Indiana, Rhode Island and Massachusetts HVAC licenses. Every EPA certified technician in any state must also hold EPA Section 608 certification before handling refrigerant, which is a federal requirement and sits outside any state or local board.

Steps to reach journeyman level

1. Register as an apprentice with the state board or city department that licenses HVAC in your area, or confirm none exists and the work is unregulated there.
2. Work the required hours under a licensed journeyman, master or contractor, keeping your own signed, dated log; boards routinely ask for employer letters, not just a personal tally.
3. Complete any required classroom or vocational hours. Several boards, including Idaho, Maryland and Rhode Island, let a completed registered apprenticeship program waive part or all of the exam.
4. Apply to the board or city once your hours and training are documented, and pay the application fee.
5. Pass the journeyman trade exam, typically scored at 70% to pass; several boards also require a short business and law exam even at the journeyman level.
6. Renew on the board's cycle, which runs from one year (Texas registration) to three years (New Mexico) depending on the state; Idaho moved its own cycle to two years in 2026.

Qualifying agents and buyer services

None of this licenses a company to contract HVAC work on its own; that still runs through a qualifying agent. A qualifying agent qualifies the company itself, as an owner or a full time W-2 employee, to hold and supervise under the license, separate from any individual journeyman or master credential an employee might also carry. See What Is a Qualifying Agent and Hire a Qualifying Agent for how that works, or our contractor qualifier services if you need one placed. For a company licensing HVAC work in more than one state, our licensing services in all 50 states page covers coordinating that across boards.

The journeyman tier is also not the same credential structure as a master, which is the next step up in most states and generally the tier required to supervise or to qualify a contractor license. For how that same journeyman to master progression works in a related trade, see our guide to the journeyman vs master electrician distinction; the licensing logic runs in parallel across the mechanical trades.

FAQ

Is there a national HVAC journeyman license? No. Each state, or in many states each city or county, sets its own HVAC journeyman requirements, exam and renewal cycle, and a license from one jurisdiction does not automatically carry into another.

How many hours of experience does an HVAC journeyman license require? It ranges from about 2,000 hours (Vermont's trained path, Massachusetts's lowest tier) to 10,000 hours (Rhode Island's Journeyperson Class I), with most boards landing between 4,000 and 8,000 hours of documented, supervised work.

Can a journeyman HVAC technician work without a contractor? Generally no. A journeyman license lets someone perform HVAC work with less day to day supervision than an apprentice, but nearly every state and city still requires that work to run under a licensed contractor or master, not as an independent operator.

What if my state does not license HVAC journeymen at all? Check with the city or county where the work is performed. States including Colorado, Illinois, Indiana, Kansas, Minnesota, Missouri, Nebraska, New York, Pennsylvania, South Dakota and Wyoming leave HVAC licensing entirely to local government, and requirements can differ from one city to the next within the same state.

Does an HVAC journeyman license cover refrigerant work? Not by itself. Anyone who handles refrigerant, in any state, also needs EPA Section 608 certification under the federal Clean Air Act, regardless of what the state or local HVAC license requires.
