Frequently asked about HVAC & mechanical permits.

What HVAC and mechanical permits does PermitCore cover?

Mechanical-trade work classifies across three segments today. Commercial MEP covers mechanical, electrical, and plumbing work on commercial buildings (service upgrades, plumbing reroutes, non-HVAC equipment changeouts). Residential MEP covers the same trades on residential structures, including HVAC replacements. Commercial HVAC is the split-out heating-and-cooling slice — RTU replacements, VAV / VRF installs, central-plant chiller work, ductwork retrofits, and equipment changeouts on commercial and multifamily buildings. Segments are overlap-free: a permit reclassified into Commercial HVAC is decremented from Commercial MEP at the source metro on the same regen, so cross-metro totals stay reconcilable.

Can PermitCore tell me which brand of equipment was installed?

Partly — and mechanical is the one vertical where we do. Where an HVAC or mechanical manufacturer is named in the permit description, we detect and surface it: see “Brands detected in permits” below and the /brands directory, both running at ≥99% precision. Two honest caveats. It is the detected subset — the permits that actually name a unit in the text, skewed to residential and small-commercial replacements — not a complete census, so a permit with no detected brand does not mean no equipment. And everything else we hold — address, scope, contractor, status, geocode, provenance, DQ flags, segment, and (for NYC) PLUTO geometry — is per-permit signal, not an install-base guarantee. Use the brand rail to find permits that name your equipment, and pair it with the segment × metro + contractor signal for full territory coverage.

Which metros have the deepest HVAC and mechanical coverage today?

Per-segment depth varies by metro. Austin leads Commercial MEP (428K permits in metro), Austin leads Residential MEP (1.1M), and New York City leads Commercial HVAC (182K). Each metro count is its own classified volume — never the cross-metro total — and every segment × metro landing page also surfaces its current count.

Why is HVAC split out from MEP?

Sales-ops queries for HVAC/mechanical equipment need just the heating-and-cooling slice, not the whole MEP rollup. Commercial HVAC was broken out so the HVAC-manufacturer and distributor audience can filter to RTU / VAV / VRF / chiller work directly. The reclassification is overlap-free — permits move from Commercial MEP into Commercial HVAC at source-metro regen — so totals reconcile. Re-roofing, envelope, and finer mechanical sub-segments continue to roll up into their parent segments until classifier precision lands per metro.

How fresh is the data?

Two signals, displayed side-by-side on every segment × metro page. Source-data freshness — a “Latest permit” date with a days-since count — is the issued date of the most recent permit we hold for that metro and segment; it tells you whether new mechanical permits are landing for the slice you care about. Index rebuilt — a separate “index rebuilt” date — is when our pipeline last recomputed the artifacts that back the page; it tells you when we last looked. We display both because a quiet segment (no recent issued permits) does not mean a stale index. Older history is queryable via the API once you sign up.

Can I integrate this into my CRM?

Yes. Every permit returns as JSON via /v1/permits — address, scope, contractor, status, geocode, provenance, DQ flags, segment, and (for NYC) PLUTO geometry are all queryable per row. Pro tier ($89/mo) includes 100K API calls/month and unlimited exports. Self-serve checkout; no sales call required.
