NYC HVAC Contractor Leads from Building Permit Data

Published 2026-05-06 · 6 min read · Audience: HVAC contractors in New York City

NYC's mechanical market is in the middle of a once-in-a-generation electrification wave. Local Law 154 (gas-equipment ban for new construction effective 2024) + Local Law 97 (carbon caps on large buildings) + state heat-pump incentives are driving heat-pump conversions, electric water heaters, and induction-cooking installations across the five boroughs. For HVAC contractors with ASHRAE + NYC DOB licensing, the permit feed is the play.
