Idaho accepts licenses fromRides the HVAC program — military lane only
Apply for your Idaho license →
Idaho’s fitter card IS the HVAC journeyman (hydronic and boiler piping are assigned to it by statute), and that program publishes no civilian partner list — plan on Idaho’s own route, except military members and spouses, whose current out-of-state license transfers with no exam. Open “Bringing your license from another state” below for the conditions, and confirm with the board before you travel.

The folded lane: hydronic and boiler piping is licensed HVAC work in Idaho, so green hands register as HVAC apprentices.
The master pipefitter license
No - Idaho has no separate master pipefitter license.
Bringing your license from another state
Idaho has no pipefitter card — but do not read that as unlicensed: the plumbing statute itself assigns gas piping, HYDRONIC SYSTEM PIPING, and boilers not subject to Industrial Commission inspection to LICENSED HVAC INDIVIDUALS. So the card a fitter needs on hydronic and boiler work is the Idaho HVAC JOURNEYMAN, and that program publishes no civilian reciprocity — plan on Idaho's route, unless you are a military member, veteran or spouse, whose current out-of-state license transfers with no exam and no fee.
Can you work while it is pending?
Not established for the HVAC journeyman card — do not start on silence. The supervised lane is HVAC apprentice registration ($10 a year) under a licensed contractor.
The exam and the hours
The Idaho HVAC journeyman exam on documented experience is the operative gate for folded fitter work (DOPL's program carries the hour standards). Two traps: do NOT try to route through the PLUMBER program — Idaho expressly refuses pipefitting hours toward plumber experience — and INSPECTED boilers are carved out of the HVAC assignment entirely, so on an Industrial Commission-inspected boiler job, confirm the required credentials with DOPL before quoting.
How apprenticing works here
HVAC apprentice registration with DOPL ($10, annual) feeding the journeyman exam — the folded entry lane for green hands on hydronic and boiler work.
The local picture
None — DOPL licenses statewide.
If you want to contract for yourself
The employing shop carries the Idaho HVAC CONTRACTOR license for hydronic and boiler scope. Pure industrial process piping with no hydronic surface showed no personal-card requirement — confirm with DOPL before staffing on that boundary.
Checked against the state board or statute. Rules change — confirm with the board before you travel or accept work. This is information, not legal advice.
