UNSPSC codes for 031

About NIGP 031

NIGP 031 Air Conditioning, Heating, and Ventilating Equipment, Parts and Accessories is a Class code under which state and local governments currently procure replacement HVAC units and system components, on-call maintenance and repair services, chiller and boiler upgrades, building automation system controls, air filters, and related ductwork and accessories for municipal facilities, schools, transit authorities, correctional institutions, and utility operations. The issuing bodies span county governments, municipal departments, independent school districts, transit authorities, and special-purpose districts. Representative recent solicitations include the Town of Rockport, Massachusetts requesting on-call HVAC maintenance under IFB with bids due November 5, 2026; Santa Clara County Procurement Department requesting chiller inspection, preventative maintenance, repairs, and replacement services under ITB with bids due November 16, 2026 and an estimated contract sum of $5.6 million; and Orange County, Florida requesting building automation system replacement and smoke/fire alarm air duct accessories at the Corrections Booking and Release Center with bids due October 20, 2026 and estimated cost of $2.89 million. Activity also includes equipment-specific procurements such as Dallas Area Rapid Transit requesting Bard brand HVAC wall pack units for wayside installation and Lawrence County, Pennsylvania requesting replacement of three existing 5-ton Bard units with bids due October 4, 2026.

Geographic activity concentrates in Massachusetts, Florida, California, Pennsylvania, and Texas with secondary activity across Michigan, Colorado, Maryland, Utah, and the broader South and Midwest. Educational facilities dominate a significant share of solicitations, with independent school districts and county school boards pursuing HVAC system replacements and building automation upgrades in tandem with capital facility improvements. Public works and facility management departments issue the majority of procurements, followed by transit authorities, county facilities management, and municipal utilities. Recent opportunities reflect elevated demand for chiller and boiler plant replacements, building controls modernization, and filter supply agreements on multi-year frameworks. Cooperative purchasing vehicles including TIPS USA and statewide job order contracts appear in the activity stream. Prevailing wage requirements are standard on state-funded and federally-funded projects; Davis-Bacon compliance and buy-local preferences surface regularly in school district and county procurements. Contract values on equipment-intensive solicitations (chiller replacement, BAS upgrades) typically range from $600,000 to $5.6 million, while on-call maintenance and filter supply agreements remain open-ended with usage-based or unit-pricing structures.
