HVAC Leads From Live Mechanical Permits

Last updated May 16, 2026

Mechanical permits (M-permits) trail the building permit by 2-4 weeks. PermitGrab lets you watch a property's permit timeline — when the building permit is filed but the M-permit has not been issued yet, you have a window to bid before the GC locks in a subcontractor.

HVAC contractors waste budget chasing dead leads. Permits tell you exactly which homes need rough-in next month.

— Marcus Reeves, Head of Permit Research, PermitGrab

Generic lead aggregators (HomeAdvisor, Angi, Networx) sell the same HVAC service-call to 4 contractors. The economics never work for new-construction work — those homeowners aren't on Angi yet, they're working through the GC.

Permit data gives you the new-construction pipeline before the GC has assembled the sub list. Phoenix and the surrounding Maricopa cities file 800-1,100 new single-family residential permits per month. Every one needs HVAC.

Frequently asked questions

Can I find HVAC leads before the contractor is selected?

Yes. Mechanical permits typically lag the building permit by 2-4 weeks. That is your bid window.

PermitGrab tracks each property's permit timeline. When the building permit is filed but the M-permit has not been issued, the GC is still finalizing the subcontractor list.

Example: A Houston builder pulls a new SFR permit Monday. The M-permit typically follows 14-21 days later. PermitGrab subscribers have 2-3 weeks to introduce themselves to the GC of record before the M-permit locks in a different HVAC sub.

How many new construction homes are built in Phoenix per month?

Approximately 800-1,100 single-family residential permits across the Maricopa County metro per month.

Maricopa includes Phoenix, Mesa, Scottsdale, Chandler, Glendale, Tempe, Peoria, Surprise — PermitGrab tags each correctly so you can filter by city or the full county.

Example: Each new-construction permit represents one HVAC system installation worth $8K-$18K residential, $50K+ commercial.

What is the typical M-permit value in Miami-Dade?

$4,500-$18,000 for residential HVAC; $50K+ for commercial.

Filter by permit_type ILIKE '%mech%' OR '%HVAC%' OR '%air condition%' to isolate the trade. Description fields often carry equipment tonnage (3-ton, 5-ton) for pre-qualifying job size.

Example: A Miami-Dade $14,000 residential M-permit = a 4-5 ton system replacement, typical 2,200-2,800 sq ft home. High-margin retrofit work.

Does PermitGrab cover heat-pump conversions and electrification incentives?

Yes. Filter by description ILIKE '%heat pump%' OR '%mini-split%' to isolate the IRA-incentive subset.

Heat-pump conversions are running 3-5x year-over-year as IRA rebates land. Phoenix, Austin, Nashville lead by volume because of the cooling-load economics in those climates.

Example: Austin filed ~280 heat-pump-tagged permits in the last 90 days — most are $9K-$22K replacement jobs eligible for the IRS Section 25C credit.

Can I get a list of GCs that file the most new-construction permits in my city?

Yes. The "Top contractors" view on every city page ranks GCs by permit volume in the last 6 months.

Use it to prioritize relationship-building. The top 5 GCs in most metros pull 30-40% of all new SFR permits — winning a sub-contractor slot with one of them is worth more than 100 cold service calls.

Example: Phoenix top-5 builders pulled 38% of all SFR permits in the last 6 months. Subscribers use the ranked list to drive a builder-partnership program instead of chasing one-off jobs.

How does PermitGrab compare to ServiceTitan or JobNimbus?

ServiceTitan and JobNimbus are HVAC field-service management software. PermitGrab is a lead source. Different layer.

They run your dispatch, invoicing, and tech assignment. PermitGrab feeds them new leads. Many subscribers pipe PermitGrab leads into ServiceTitan via the export feature.

Example: A Phoenix subscriber pulls the weekly new-SFR permit list from PermitGrab, drops it into ServiceTitan as fresh opportunities, and assigns outreach to inside sales.
