How Maryland HVAC Technician license verification works
A HVAC Technician in Maryland is licensed by the MD Contractor Licensing Board. PrimaryCheck looks the license up live at the board's public verification system (board lookup) by license number, or by name when no number is supplied. The record the board publishes is captured as evidence, hashed, and rendered into a proof PDF.
Fields returned for this board: license_number full_name first_name middle_name last_name suffix former_name category expiration city state zip trade_name address insured status.
Board note: MD-DLLR: Home Improvement Commission (calling_app HIC: CONTRACTOR/SALESMAN; the MHIC licence 05-nnnnnn-nn is printed in the address column, the reg field is the person's own number; a claim carrying the MHIC form falls back to a name search), Master Electricians (ME, insurance Status column), Plumbing (PLM, Insured column), HVACR (HVAC) on the Maryland Labor Public Query; plain HTTPS, no captcha; active licensees only; no DOB, no discipline.
