How do I verify a HVAC contractor is licensed in New York?

Instead, licensing is handled by NYC (Department of Consumer and Worker Protection), and individual counties such as Nassau, Suffolk, Westchester, and Rockland — each with its own license lookup. For NYC, verify Home Improvement Contractor (HIC) status at the DCWP Citizen Access portal; elsewhere, contact the county Consumer Affairs office. Confirm active status, insurance on file, and any required bond.
