HVAC Permit Leads in Chicago: 2,008 Mechanical Permits in 90 Days (2026)
Chicago is a mechanical-trade town by climate and by code. In the last 90 days the city filed 2,008 HVAC permits, the second-busiest trade behind electrical, inside a feed that tracks 12,981 contractors and 4,052 verified phone numbers.
No market rewards an HVAC contractor for paying attention like Chicago does. The climate alone guarantees year-round mechanical work — brutal winters drive heating installs and replacements, and the humid summers keep cooling demand high. The data backs it up: in the trailing 90 days, Chicago filed 2,008 HVAC permits, the second-busiest trade category in the city behind electrical.
PermitGrab tracks 13,211 indexed permits in Chicago with 2,669 filed in the last 30 days, the most recent dated June 15, 2026. Underneath that sit 12,981 named contractor profiles, 4,052 of which carry a verified phone number, and 6,732 permits that publish a contractor contact phone.
Where the HVAC Work Is
Chicago's 2,008 HVAC permits over 90 days are not evenly spread — they cluster in exactly the property types the city is full of. The aging housing stock of greystones, two-flats, and brick walk-ups means furnace and boiler replacements are a constant. Commercial rooftop-unit work follows the city's warehouse-to-residential conversions and tenant build-outs. And new construction adds full mechanical systems to the pipeline. Every one of those permits is a property where a mechanical system was just touched — and where the next service contract, warranty, or follow-on job is up for grabs.
The Full Chicago Trade Picture
HVAC sits inside a deep, multi-trade feed. The busiest Chicago trade categories over the last 90 days:
- Electrical — 2,335 permits.
- HVAC — 2,008 permits.
- Interior Renovation — 600 permits.
- Landscaping & Exterior — 497 permits.
- Signage — 469 permits.
- Plumbing — 422 and Roofing — 412 permits.
For an HVAC contractor, the electrical and renovation volume matters too: those permits flag properties undergoing the kind of work that often pulls a mechanical contractor in next.
Why HVAC Contractors Use Permit Data Over Lead Marketplaces
A permit is a record of work that already happened on a real, addressable property — not a shared "lead" sold to four competitors at once. When you see a mechanical permit on a building, you know the system, the address, and the date, and on thousands of Chicago records you get the contractor phone too. That lets you build genuine business-development lists: subs looking for overflow work, suppliers targeting active shops, and service companies chasing the install base that just turned over.
