How Delaware HVAC Technician license verification works
A HVAC Technician in Delaware is licensed by the DE 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 license_type board licensed_by status issued effective expires multistate city state zip actions documents flags.
Board note: Electrical Examiners (Master T1-, Journeyperson TJ-, Residential, Limited, Special-*), Plumbing/HVACR (Master Plumber PL-, Master HVACR HM-) on DELPROS. Delaware has no state general-contractor license (Division of Revenue business license only) → contractor_general has no source.
