How to Win NAICS 238220 Contracts

Federal agencies classify solicitations using NAICS codes to identify the type of work or product being procured. NAICS 238220 (Plumbing, Heating, and AC Contractors) must be listed on your SAM.gov registration to appear in searches and receive notifications for matching opportunities.

Each NAICS code has a small business size standard, which determines whether your firm qualifies as "small" for set-aside competitions. Check the SBA's size standards table for NAICS 238220 — the threshold may be based on annual revenue or number of employees.

Many Plumbing, Heating, and AC Contractors contracts are awarded through multi-award indefinite delivery/indefinite quantity (IDIQ) vehicles. Winning a spot on an IDIQ allows you to compete for task orders over 5–10 years, providing a predictable pipeline of work.

Past performance is critical for NAICS 238220 opportunities. Start with smaller contracts (micro-purchases under $10,000 or simplified acquisitions under $250,000) to build your track record, then pursue larger opportunities as your CPARS ratings improve.
