Commercial HVAC

What it covers

Commercial-grade HVAC work on commercial and multifamily buildings — RTU replacements, VAV / VRF system installs, central-plant chiller work, ductwork retrofits, and equipment changeouts. Building-character definition: HVAC permits on multifamily R-2 buildings classify here because the trade itself uses 'commercial HVAC' in the building-character sense (the contractor license class, manufacturer product catalog, and distributor territory plan all align this way). Split out of Commercial MEP + Multifamily Alteration on classifier reclassification.

How a permit lands in Commercial HVAC.

Every silver permit flows through a two-stage classifier. The deterministic stage maps the structured signals — work_class, the normalized permit type, and the building sub-type — into the segment vocabulary where the mapping is unambiguous. The machine-learning stage handles the cases that aren't direct lookups: multi-vocab permit-type strings, ambiguous occupancy spans, and jurisdictions that bundle categories. The segment is the classifier's output, the same axis across every metro — so commercial_hvac means the same thing in NYC as in LA even though the upstream jurisdictions emit completely different raw permit-type strings.

When the signal genuinely isn't there, we say so. A row with no assignable segment degrades honestly — to its work-nature, then to its raw source type, and only to “Unclassified” when truly nothing is known. We never guess a segment to fill a gap; an honest Unclassified is the floor, and field-level data-quality flags surface when the classifier had low confidence. That restraint is the point — the classification is only worth selling on if the “don't know” is honest.
