How to Get an HVAC License, State by State

There is no national HVAC license, and the credential is often not held by the technician. Across the 51 US jurisdictions in this atlas, 19 license the individual technician, 19 license only the HVAC or mechanical contractor (the business and its qualifying individual), 2 require a statewide business registration or bond while individual competency is set locally or is voluntary, 10 have no state HVAC credential at all and leave it to cities and counties, and Montana licenses HVAC at no level. Getting that distinction right is the whole job: in a contractor state, the “HVAC license” people search for is not something the state issues to an individual.

Every figure below comes from that jurisdiction’s own board or statute, is dated on its state page, and is re-checked automatically — see what changed and our corrections .

Separately from any state license, federal law applies in all 50 states. EPA Section 608 certification is required of technicians who service equipment that could release refrigerants, it is typed to the equipment rather than the job title, and it does not expire — and car A/C work for payment falls under Section 609 instead. Neither is a state license. See EPA 608 certification and how 609 differs .

Who the license is actually issued to

• The individual worker — 19 jurisdictions: Arkansas , Connecticut , Delaware , District of Columbia , Idaho , Iowa , Kentucky , Maine , Maryland , Massachusetts , New Hampshire , New Mexico , Oklahoma , Rhode Island , Texas , Vermont , Virginia , Washington , West Virginia .

• The contractor, not the worker — 19 jurisdictions: Alabama , Alaska , Arizona , California , Florida , Georgia , Hawaii , Louisiana , Michigan , Mississippi , Nevada , New Jersey , North Carolina , North Dakota , Ohio , Oregon , South Carolina , Tennessee , Utah . In these states the state credential belongs to the business and its qualifying individual; employees generally work under it rather than holding their own state license.

• A statewide business registration or bond — 2: Minnesota , Wisconsin . A mandatory statewide filing exists, but individual competency is licensed elsewhere (locally) or is voluntary; the state pages say which.

• No state license — city or county rules — 10: Colorado , Illinois , Indiana , Kansas , Missouri , Nebraska , New York , Pennsylvania , South Dakota , Wyoming . There is no statewide credential to apply for; the page for each of these names the local authorities that do license, and what they require.

• Not licensed at any level — Montana . There is no state credential and no local one to fall back on; the state page proves the negative from the state’s own code and agency listings.

What the credential takes where a state issues one

There is no standard experience requirement, and most states do not state one in hours. Only 12 of the 40 jurisdictions with a state credential publish an hours figure for the entry-level tier, and no single figure dominates them — they run from 2,000 to 10,000 hours. The other 28 state experience in years, or as an apprenticeship, degree or combination; each state page carries its board’s own wording. Note too that in the 19 jurisdictions that license the contractor, whatever the requirement is, it attaches to the business’s qualifying individual — not to every technician doing the work.

The exam is usually run by a third-party vendor, not by the board. Where a record names exactly one vendor — 29 of the 40 jurisdictions with a state credential — it is PSI in 20, Prov in 7, Pearson VUE in 1, Prometric in 1. The other 11 name more than one approved vendor, administer the exam themselves, or attach no exam to the mandatory credential; a page saying “See page” in the table below means the record does not reduce to one vendor, never that there is no exam.

Fees, renewal periods and continuing-education hours are not summarised here on purpose. Boards publish fee schedules (application, exam, license, reinstatement) rather than a single price, and renewal is written per credential tier. Each state page lists what its board publishes, with the date it was last verified — the averages you find elsewhere are the thing this atlas exists to replace.

How getting licensed works

The order is close to identical wherever a state issues its own credential; what varies is who qualifies and how much of it is required. Each state page sets out the steps in the board’s own words.

1. Confirm which credential your state issues — to the individual, to the contractor, or only locally. Every state page below states which, with the board’s own wording.
2. Accumulate and document the experience the board recognises — supervised on-the-job hours, years in the trade, an approved apprenticeship or a degree, depending on the state, and evidenced the way that board asks for it.
3. Apply to the board and be approved to sit the exam — the application, its evidence of experience, and its fee generally come before exam scheduling.
4. Pass the exam, where the credential has one, through whichever vendor or in-house process that board uses.
5. Hold the license current — renewal on the board’s cycle, plus any continuing education, and any separate registration a city or county requires before you work there.

Every jurisdiction compared

“Set locally” marks a jurisdiction with no statewide credential — its page names the local authorities instead. “See page” means the record does not reduce to one value (several approved exam vendors, or a requirement stated in another form), not that there is no requirement.
