UNSPSC 40000000: Distribution and Conditioning Systems and Equipment and Components

This segment includes systems, devices and components used to control the movement or conditioning of air, gases or fluids. This segment also includes equipment and components used in plumbing, air cooling or heating (HVAC).

UNSPSC 40000000 Distribution and Conditioning Systems and Equipment and Components, a Segment code, encompasses the equipment and systems state and local governments purchase to manage the flow, storage, and conditioning of liquids, gases, and other materials—including HVAC units, boilers, chillers, pumps, filters, piping, dampers, and building automation controls. Recent state and local solicitations reflect active procurement of replacement HVAC equipment for transit facilities, corrections and municipal buildings, schools, and wastewater treatment plants; maintenance and repair services for existing mechanical and thermal systems; air filter supply agreements; and complete system upgrades integrating controls, fire/smoke dampers, and energy recovery.

Issuing bodies across the code span state departments, counties, cities, independent school districts, transit authorities, housing authorities, and special-purpose utilities. Dallas Area Rapid Transit (DART), Charles County Maryland (transit and wastewater), Orange County California (waste and recreation), Orange County Florida (corrections), the State of Connecticut, and multiple school districts—including Dayton, Taylor, Laredo, and Cherokee County—appear as repeat buyers. Geographic concentration is evident in Texas (Dallas, Austin, San Antonio, Houston, Laredo, Harris County, Williamson County), California (Orange County, Alameda, Palm Bay), Florida (Orange County, Volusia County), and the Upper Midwest (Michigan, Connecticut, Colorado). Representative recent opportunities include DART's October 30, 2026 bid for five-ton, three-ton, and two-ton BARD HVAC wall pack units for wayside installation; Charles County Maryland's October 29, 2026 ITB for complete construction of a 180,000-square-foot VanGo Transit Operations and Maintenance Facility with HVAC, boiler, chiller, and building systems integration under Davis-Bacon and Buy America requirements; Orange County Florida's October 20, 2026 sealed-bid solicitation for a $2.89 million Corrections Booking and Release Center building automation system and smoke/fire alarm air duct accessories replacement; and Dayton Public School District's October 23, 2026 RFP for HVAC and Building Automation Systems upgrades across three school buildings. On-call and framework agreements for maintenance, repairs, and parts supply are also active, reflecting steady demand for managed services across distributed municipal portfolios.
