Federal Contractors — Plumbing, Heating, and Air-Conditioning Contractors (NAICS 238220)
U.S. Location Dataset // 6,156

6,156 US federal contractors with primary NAICS 238220, Plumbing, Heating, and Air-Conditioning Contractors — active SAM.gov registrations for contract awards, from the 2026-09-06 SAM.gov public extract. 100.0% carry a street address, 62.6% a website, 100.0% a primary NAICS code with its title, 100.0% a CAGE code, 100.0% the name of the government business point of contact, and 39.2% are small businesses for their primary NAICS. Email addresses where the firm publishes one on its SBA profile. Every row carries the UEI and CAGE code, physical and mailing address, entity structure, state and country of incorporation, entity start date, every NAICS and PSC code with titles, the set-aside and ownership flags SAM records (woman-owned, veteran-owned, service-disabled veteran-owned, minority-owned, 8(a) and HUBZone certifications with expiry dates), the purpose of registration, and the initial, activation, last-update and expiration dates of the registration. Registrants who opted out of public display in SAM.gov (31,437 in this extract) are excluded from every product. Built from the SAM.gov public entity extract — the monthly file the General Services Administration publishes of every registration in the System for Award Management, decoded with GSA's own layout, the Census NAICS list and the GSA PSC manual.

All 6,156 records, as published — the complete set rather than a sample. That matters most for coverage and gap questions: put together the same list from partial searches and every location you miss reads as a gap that is not there, so the answer is wrong rather than merely late. Assembling the U.S.-wide coverage by hand also means one query per area against sources that cap what they return per search.
