A journeyman HVAC license is the mid-level license a state issues to an HVAC worker who has documented the required supervised experience and passed that state's journeyman exam.
Getting one means 2 years of field work in Kentucky, 3 in Oklahoma, at least 4 years on an apprentice licence with 6,000 training hours in Maryland — every state writes its own number.
Only about a quarter of U.S. jurisdictions license HVAC workers at all; this page covers the rung where they do.
What is a journeyman HVAC license?
A journeyman HVAC license is an individual work licence — the credential that says you may perform HVAC work as a qualified worker, past the apprentice stage but below master and contractor.
It is issued by a government body: a state board in states that license workers, or a city or county where licensing is local.
No federal agency defines the rung — what "journeyman" means, how many hours it takes and what it legally allows are written in each state's own licensing law, and they differ state by state.
Where the rung exists, it sits on a ladder.
The District of Columbia licenses refrigeration and air-conditioning mechanics individually at apprentice, journeyman and master levels, with "limited" versions for equipment at or below 25 compressor horsepower.
Idaho runs four HVAC classifications: apprentice, journeyman, HVAC contractor and HVAC specialty contractor.
Iowa's ladder is apprentice, then journeyperson, then master.
The apprentice below you works under supervision — in Idaho an apprentice may do HVAC work only under the supervision of an HVAC journeyman or contractor; the journeyman licence is what marks you as the qualified worker on the crew.
The name changes by state, so read the licence list literally.
Kentucky issues a journeyman HVAC mechanic licence through its Department of Housing, Buildings and Construction.
Maryland's HVACR board lists Journeyman and Journeyman Restricted among its licence types.
New Mexico's HVAC worker credentials are JR — Journeyman Refrigeration — and JSM, Journeyman Sheet Metal.
If the job ads in your state ask for a "journeyman's license," the licence they mean is whichever of these your state actually issues — and if you're not sure what the work at that level looks like, browsing live HVAC technician jobs shows how employers describe it.
Which states have a journeyman HVAC license?
There is no national list, because most of the country never created the rung.
As of September 2026, 13 U.S. jurisdictions license HVAC workers at an apprentice, technician or journeyman rung — only about a quarter of jurisdictions; the rest license the contractor, license only masters, license pieces of the work, or leave HVAC to cities.
Among those 13, the middle rung is a journeyman (or journeyperson) licence in several:
- Kentucky — journeyman HVAC mechanic, under a master HVAC contractor
- Maryland — Journeyman and Journeyman Restricted HVACR licences
- Oklahoma — journeyman licences under the Construction Industries Board's Mechanical Licensing Act
- Virginia — journeyman among the DPOR tradesman levels for HVAC
- Idaho — journeyman classification under the HVAC Board
- Iowa — journeyperson licences by discipline
- Rhode Island — journeyperson licences through the Department of Labor and Training's mechanical board
- New Mexico — JR and JSM journeyman certificates of competence
- Connecticut — journeyperson licences through the Department of Consumer Protection, led by the S-2 Unlimited Heating, Piping and Cooling Journeyperson licence
- District of Columbia — journeyman among the Refrigeration and Air Conditioning Mechanic levels
The other three of the 13 are worker-licence jurisdictions without a journeyman title, which surprises job seekers in each.
Texas's tiers are Registered Technician, Certified Technician and ACR Contractor (Class A/B) — there is no journeyman or master HVAC tier in Texas.
West Virginia certifies HVAC Technician, HVAC Residential Technician and Technician in Training.
And Arkansas requires every individual who designs, installs, services or repairs an HVACR system to hold a state licence or registration — workers who are not class holders carry a registrant and may work only for an HVACR licensee — a worker-licence model with no journeyman title either.
Two more jurisdictions sit at the top of the ladder only: Delaware and New Jersey license masters alone, with no journeyman licence beneath — Delaware's board issues Master HVACR and Master HVACR Restricted and nothing else.
One route to Delaware's master licence runs through the journeyman certificate earned in a federally registered apprenticeship plus 2 years under a master — on that route the certificate is a prerequisite, not a licence of its own; the other route is 7 years under a master plus the apprenticeship equivalency ("by-pass") test.
Where the state stays out, the journeyman card can still exist locally.
Kansas has no state HVAC licence, but its counties and cities license journeyman HVAC mechanics under uniform state standards.
Florida law authorizes counties and municipalities to issue journeyman licences in the mechanical and HVAC trades, and Denver issues Heating and Ventilating Journeyman certificates.
A broader group of states — Illinois, Indiana, Kansas, Minnesota, Missouri, Montana, Nebraska, North Dakota and Wyoming — have no state HVAC licence at all, so any licence is a city or county one.

How many hours and how much training does it take?
No federal hour total exists — experience hours are set state by state.
The verified state rules show three structures, often mixed: a stretch of years in supervised work, an hour count, or completion of a registered apprenticeship.
Trade school usually substitutes for only part of it, and every state caps that substitution differently.
- Kentucky — 2 years of HVAC work under a master HVAC contractor (or 2 years of verifiable HVAC work); one academic year of a department-approved HVAC curriculum counts toward at most one year of it
- New Mexico — 2 years of experience within the 10 years before applying; accredited technical or apprenticeship training counts at half credit and may cover at most half the requirement
- Oklahoma — 3 years of verifiable experience in the category, with one year counted as 2,000 hours, or a CIB-approved school program plus reduced experience (for example a 1,000+ hour program plus one year)
- Maryland — an apprentice licence held for at least 4 years with at least 6,000 hours of training under a licensed contractor
- Idaho — 8,000 hours as an apprentice plus 576 hours of board-approved instruction, or 16,000 hours of HVAC experience without them
- Virginia — 4 years of experience plus 240 hours of vocational training, or 2 years plus an associate degree, or 8 years with no formal training
- Iowa — at least 4 years of practical experience as an apprentice in a program registered with the U.S. Department of Labor's Office of Apprenticeship; you may sit the exam up to 12 months before finishing
- Rhode Island — a 10,000-hour registered apprenticeship for the journeyperson refrigeration technician licence
- Connecticut — the equivalent-experience route to the S-2 unlimited journeyperson licence takes 576 classroom hours plus 8,000 hours of on-the-job training
The local cards follow the same logic at city scale.
A Kansas journeyman HVAC certificate takes at least 2 years of documented field experience under a journeyman or master, with up to 1 year in trade school of at least 930 program hours.
Florida's local journeyman licence takes a registered state-approved apprenticeship or at least 12,000 hours of on-the-job training.
Denver's Heating and Ventilating Journeyman certificate takes 4 years — a minimum of 7,000 hours — of field installation experience.
Because each of these numbers lives in that state's (or city's) law and gets amended, treat them as the shape of the requirement and confirm the current figure with the board before you plan around it.
What is the journeyman HVAC license exam like?
Every example jurisdiction above uses an exam as the standard route to the journeyman rung (with apprenticeship exemptions in a couple, covered below); the vendors, passing scores and fees are set by each licensing body.
A few verified specifics show the range.
Maryland scores its journeyman exam at 70%.
New Mexico's journeyman exams are run through PSI, are open book, require 75% to pass, and cannot be retaken more than twice in 30 days — candidates must be pre-approved and test within 6 months of eligibility.
Oklahoma's mechanical exams are also PSI and open book at the journeyman level, testing the statewide codes Oklahoma has adopted.
Local jurisdictions standardize differently.
Any Kansas city or county that licenses HVAC must use ICC, IAPMO or Prometric exams, set the passing score at 75%, and may not add questions of its own; Denver's journeyman certificate requires the ICC F31 National Standard Journeyman Mechanical exam.
Florida requires at least 75% on a proctored journeyman exam — Block and Associates or another board-approved vendor.
Kentucky's journeyman HVAC mechanic exam costs $50, non-refundable.
Fees stack from both sides elsewhere: Iowa charges a $35 exam application plus licence fees, Oklahoma charges a $25 application and $50 for the initial journeyman licence, and Connecticut charges a $90 journeyperson application with exam fees paid separately to the exam vendor.
Two exits from the exam exist where apprenticeships are strong.
Maryland grants the HVACR journeyman licence without the exam to graduates of a program approved by the Maryland Apprenticeship and Training Council who hold the certificate of completion.
The District of Columbia waives the journeyman exam entirely for graduates of a nationally certified apprenticeship — classroom plus 8,000+ hours, or 4 years, of on-the-job training under a master.
Note the federal layer sitting next to all of this: DC also requires EPA CFC Universal certification to sit its journeyman exam, and New Mexico's JR certificate requires proof of EPA refrigerant-recovery compliance.
EPA 608 is a federal refrigerant-handling certification, separate from the state licence — the exam that gets you the card is not the exam that gets you the licence.

What does a journeyman HVAC license let you do?
The licence makes you the qualified individual worker — and in the states examined, it keeps you tied to a licensed employer rather than making you a business.
An Idaho HVAC journeyman works in the employ and under the direction of an HVAC contractor.
A New Mexico journeyman may work only when employed by an entity licensed — or holding an annual permit — for that type of work, and the certificate is individual and non-transferable.
Denver's journeyman certificate is valid only while you are employed by a Heating and Ventilating Contractor Class A or an HVAC contractor.
The rung also puts you on the supervising side of the apprentice relationship.
In Idaho, an apprentice may do HVAC work only under the supervision of an HVAC journeyman or contractor — the journeyman licence is what makes you one of the people an apprentice may legally work under.
Kentucky draws the boundary from the other side: unlicensed employees working under a master HVAC contractor, who are not journeymen or apprentices and do not contract on their own, are exempt from the licensing law — the licence is required of those who hold themselves out as journeymen, not of every pair of hands.
What it does not do is make you a contractor.
The journeyman licence is not a contracting licence: in these schemes the employer holds the contractor credential, and who may pull a permit is its own rule — permit rules differ by state, and our research found no federal answer, so check with the local building department before you promise permit-covered work.
Portability is likewise a patchwork.
Maryland's HVACR board has reciprocal agreements only with Delaware and Virginia.
Florida's counties and municipalities must recognize a journeyman HVAC licence issued by any other Florida county or municipality.
A Kansas licence based on a designated standard exam is valid in every other Kansas jurisdiction that licenses HVAC, while a licence based on a city's own exam is valid only in that city unless a reciprocal agreement says otherwise.
Reciprocity agreements in general differ state by state.
The licence's other job is as the rung you step off from.
Maryland's master HVACR licence requires at least 3 years of active experience as a licensed journeyman plus 1,875 hours worked in the year before applying.
Rhode Island requires at least 1 year as a licensed journeyperson before you can sit its mechanical master exams.
A Kansas master certificate takes 2 years as a journeyman or 4 years of field experience, and Delaware's Master HVACR takes the apprenticeship journeyman certificate plus 2 years under a master.
If contracting or the master tier is your destination, the journeyman years are how the states that use the rung make you earn it.
This page is career information, not legal or licensing advice. Journeyman licensing is set by state boards and, where licensing is local, by city and county offices — confirm the current requirements with the authority for where you work before you apply, sit an exam or turn down work.
