NIGP Code 031-00 — Air Conditioning, Heating, and Ventilating Equipment, Parts, and Accessories — is a standardized State, Local, and Education (SLED) procurement classification within Class 031 — Air Conditioning, Heating, and Ventilating Equipment of the National Institute of Governmental Purchasing (NIGP) Commodity/Services Code taxonomy. Across all 50 states, over 33 state central purchasing offices and thousands of county governments, municipal utilities, public university systems, transit authorities, and K-12 school districts obligate approximately $3.2 Billion annually under NIGP 031-00, generating 710+ Bids active Invitations for Bid (IFBs), Requests for Proposals (RFPs), and informal quote requests each year. The NIGP taxonomy uses a hierarchical structure where the 3-digit Class (031) identifies the broad commodity or service family (Air Conditioning, Heating, and Ventilating Equipment) and the 5-digit Class-Item code (031-00) pinpoints the specific commodity (hvac equipment) deliverable. When state and municipal buyers post solicitations on portals such as Texas ESBD & BuyBoard, Florida MFMP, California Cal eProcure, and Virginia eVA, automated bid invitations are dispatched exclusively to vendors who have added NIGP Class 031 and Item 031-00 to their supplier registration profiles. Typical scopes of work under NIGP 031-00 include Direct OEM Replacement Rooftop Units (RTUs), Chillers, Boilers & Split Heat Pumps; VAV Terminal Boxes, Variable Frequency Drives (VFDs), Compressors, Motors & Coils; and Pleated MERV-13 Air Filters, HEPA Filters, UV-C Germicidal Lamps & Belts. In addition to standalone municipal RFPs and sealed low-bid IFBs, a substantial share of NIGP 031-00 purchasing flows through cooperative purchasing agreements and statewide term contracts—including OMNIA Partners / Sourcewell / BuyBoard / TIPS HVAC. Holding or partnering on a cooperative master contract allows public sector buyers to issue direct purchase orders without repeating a lengthy formal solicitation cycle. Furthermore, most state and municipal procurements under NIGP 031-00 enforce Historically Underutilized Business (HUB), Minority/Women-Owned Business Enterprise (MBE/WBE), Disadvantaged Business Enterprise (DBE), or Service-Disabled Veteran-Owned Business participation goals.
