UNSPSC 40100000: Heating and ventilation and air circulation

UNSPSC 40100000 Heating and ventilation and air circulation is a Family code that encompasses the supply and installation of HVAC equipment, components, controls, and maintenance services across state and local facilities ranging from municipal office buildings and correctional institutions to schools, transit authority properties, and specialized infrastructure like wastewater treatment plants. Recent state and local solicitations under this code include equipment replacements (rooftop units, chillers, boilers, wall-pack units), system controls and building automation upgrades, air filters and consumables, and preventative maintenance and repair services on an as-needed or on-call basis. Issuing bodies span county governments (Erie County, Lawrence County, Howard County, Volusia County, Orange County), municipalities and cities (Dallas, Fort Worth, Charlotte, Meriden, Belchertown, Attleboro, Palm Bay, Jackson, Redding), independent school districts (San Antonio, Taylor, Dayton, Cherokee County), transit authorities (DART), higher-education institutions (University of Houston), and special-purpose districts including wastewater utilities (Tucson Water, Beacon Falls). School districts and county facilities appear as repeat buyers across the recent opportunity set, particularly for building automation system integration and HVAC replacements tied to broader facility modernization programs.

Recent representative solicitations span all regions and multiple notice types. Orange County, Florida issued an IFB for $2.89 million in building automation system and fire/smoke alarm air duct accessories at a corrections facility with sealed bids due October 20, 2026. The Housing Authority of the City of Alameda posted an RFP for five rooftop HVAC package unit replacements and one reinstallation with responses due October 27, 2026 and mandatory pre-bid walk on October 8, 2026. Volusia County, Florida solicited comprehensive removal and replacement of air handling units, fire/smoke dampers, and building automation systems at its Branch Jail with bids due August 20, 2026 and an estimated project cost of $3,930,030. Smaller maintenance contracts include the City of Somerville, Massachusetts requesting sealed bids for on-call HVAC services across multiple municipal locations with bids due October 23, 2026, and Dallas Area Rapid Transit requesting bids for BARD HVAC wall pack units (5-ton, 3-ton, and 2-ton capacities) for wayside installation with bids due October 30, 2026. San Antonio Independent School District has posted multiple continuous open-ended solicitations for general maintenance services including repairs and parts on an as-needed basis. Massachusetts courts, through the Office of Court Management, have issued multiple prevailing-wage-compliant RFBs for chiller replacement and split-system air-conditioning installations at courthouses. Activity concentrates in the Southeast (Florida, Volusia County), Mid-Atlantic (Pennsylvania, Massachusetts), and Texas, with smaller opportunities scattered across Connecticut, Michigan, Colorado, and Arizona jurisdictions.
