UNSPSC 40101709: Air handling unit

A device used to cool, heat, dehumidify, humidify, filter, circulate and ventilate air within a building.

UNSPSC 40101709 Air handling unit (Commodity) represents equipment and components for mechanical systems in state and local facilities—cooling towers, chillers, boilers, and associated HVAC package units—as well as discrete replacement parts such as geareducers. Recent solicitations show state and local agencies buying rooftop HVAC package unit replacements, chiller and boiler maintenance and repair services, cooling tower water treatment, and individual mechanical components for existing systems. Issuing bodies include city utilities departments, county governments, school districts, housing authorities, and transit agencies. Work typically involves replacement of failed equipment with code-compliant, high-efficiency units; preventative and emergency maintenance on chilled-water and heating systems; and specialized services such as cooling tower cleaning, bore scope inspection, refrigerant recycling, and water-treatment chemical management. Scope qualifications are stringent: contractors must hold manufacturer certifications (C-20 HVAC license in California, Type III or Universal HVAC certification in Florida), comply with prevailing wage where applicable (Davis-Bacon on HUD-funded projects), manage hazardous materials (refrigerant recycling under Clean Air Act Section 608, mercury and PFAS restrictions), and in some cases meet Section 3 employment benchmarks. Insurance requirements typically demand $1 million to $2 million Commercial General Liability per occurrence and Workers' Compensation at statutory limits. Contract terms range from one year to five years with optional renewals.

Geographic activity spans multiple regions: California (Alameda Housing Authority, Long Beach Public Utilities), Texas (City of Austin, Houston ISD, San Antonio), Florida (Monroe County, Solid Waste Authority of Palm Beach County), Michigan (state DTMB), Pennsylvania (Harrisburg Housing Authority), Arizona (City of Phoenix), North Carolina (City of Charlotte transit authority), and Connecticut (Norwalk Public Schools). Recent representative opportunities include the City of Austin's geareducer RFQ (IFQ1100BAS1105, due October 16, 2026) specifying a single Marley Cooling Tower Series 4000 unit with HUB/M/WBE preference-tier notification; the Housing Authority of the City of Alameda's RFP for five rooftop HVAC package unit replacements and one condenser unit relocation (due October 27, 2026, 30-point qualifications weighting, mandatory October 8 bid walk, $2 million CGL and workers' comp required); San Luis Obispo County's SB/DVBE-only IFPQ for chiller, boiler, and air-handler maintenance and repair (due October 2, 2026); the City of Charlotte transit authority's RFP for boiler and chiller preventative maintenance on Trane, Carrier, and other equipment (due October 15, 2026); and the City of Phoenix's three-year cooling tower water treatment contract with monthly service reporting, semi-annual cleaning, and bore scope inspection requirements (IFB 27-FMD-013, contract start October 1, 2026). Earlier in the year, Houston ISD solicited HVAC chiller replacement at three school facilities with December 31, 2026 completion (RFP 270003, due July 29, 2026) and Harrisburg Housing Authority issued an IFB for boiler steam supply line riser repairs across 240 residential units subject to Davis-Bacon and HUD Section 3 requirements (IFB 2026-08, due August 1, 2026). Activity is steady across the calendar year with no recent quiet period.
