Plumbing & HVAC contracts — common questions

How do I get government HVAC or plumbing contracts?expand_more

Register free on SAM.gov under NAICS 238220, then watch the installations near you — bases and VA facilities post this work year-round. Licensed, insured, and able to pass base access requirements covers most of the entry bar; federal past performance in any mechanical trade helps you win the next one.

What NAICS code covers HVAC and plumbing work?expand_more

NAICS 238220 (Plumbing, Heating, and Air-Conditioning Contractors) covers both trades in one code. The SBA size standard for it is receipts-based — most independent mechanical contractors qualify as small.

Is this work set aside for small business?expand_more

Heavily. Facility mechanical work fits the Rule of Two almost everywhere, so a large share is small-business set-asides, with frequent 8(a) and SDVOSB set-asides on top. No certification is needed for the plain small-business ones — just self-certified size.
