Maryland’s fitter card IS the HVACR journeyman (hydronic systems — liquids or steam — are inside its statutory scope), and that card holds the one verified two-way lane in this space: Maryland and Virginia each accept the other’s HVACR/HVA journeyman, per both boards’ own documents.

Maryland has no pipefitter-titled license - hydronic work is defined into HVACR practice, so the master tier for fitter work is the HVACR master.
Cómo traer tu licencia de otro estado
Maryland has no pipefitter card — the fitter's card here is the HVACR JOURNEYMAN, because the statute defines hydronic systems ('liquids OR STEAM to transmit or remove heat') straight into licensed HVACR services. And that card holds the one verified two-way lane in this whole trade: Maryland and Virginia each accept the other's HVACR/HVA journeyman, per both boards' own documents.
Coming from anywhere else, it is Maryland's own ladder.
¿Puedes trabajar mientras está en trámite?
Not established — no work-while-pending provision is recorded for the HVACR program. The licensed entry lane is the HVACR APPRENTICE license.
El examen y el horario
The Maryland HVACR ladder runs apprentice (a real license — the qualification clock runs on licensed years) to JOURNEYMAN to master, with PSI examinations; the board's requirements page carries the hour standards. Three boundary checks: GAS IS A DIFFERENT WORLD (fuel-gas piping belongs to the plumber/gas-fitter and natural-gas-fitter ladders, with their own Baltimore County and WSSC layers); the LIMITED license class is maintain-and-repair only — it cannot install; and industrial process piping outside comfort systems showed no personal card — confirm with the board before staffing on it.
Cómo funciona el programa de aprendizaje aquí
The HVACR APPRENTICE license — the mandatory entry tier and the clock: licensed apprentice years plus hours qualify you for the journeyman exam.
La situación local
The state HVACR license governs folded fitter work statewide. The local layer that matters in Maryland belongs to the PLUMBING/GAS world — Baltimore County and WSSC license plumbers and gas fitters in their territory — which does not create a fitter card but does own any fuel-gas piping your crew touches there.
Si quieres trabajar por cuenta propia
HVACR CONTRACTOR structure sits above the worker tiers, master-anchored. Verify the employing contractor alongside the worker's journeyman card, and read the actual license CLASS — a limited card on an install job is the mismatch to catch.
