How to Win Plumbing, Heating & HVAC Government Contracts

Federal agencies spend billions annually on plumbing, heating & hvac services under NAICS code 238220. Opportunities are posted on SAM.gov with response windows of 14-30 days — most small businesses miss them because they don't check daily.

Requirements to bid: You need an active SAM.gov registration (free), a DUNS/UEI number, and in most cases the relevant trade licenses for your state. Many plumbing, heating & hvac contracts are set aside exclusively for small businesses, 8(a) firms, HUBZone, WOSB, or service-disabled veteran-owned businesses.

Why use GovBidScope: We aggregate SAM.gov postings under NAICS 238220into one browsable feed with plain-English titles and set-aside tags so you can scan the list quickly instead of clicking through 40-page solicitations one at a time.

Frequently Asked Questions

What is NAICS 238220?

NAICS 238220 covers plumbing, heating & hvac businesses. The federal government uses this code to classify contracts by industry, so agencies can find qualified vendors for specific types of work.

How many plumbing, heating & hvac contracts are posted per month?

Typically 50-200+ opportunities per month under NAICS 238220, depending on the fiscal year cycle. Volume spikes in Q4 (July-September) as agencies spend remaining budgets.

Can I bid if I'm a small business?

Yes. The federal government is required to award at least 23% of contracts to small businesses. Many contracts under NAICS 238220 are set aside exclusively for small businesses or disadvantaged categories (8(a), HUBZone, WOSB, SDVOSB).
