UNSPSC 72151204: HVAC ventilation and duct work construction service

The building of ventilation and duct work owned by others

UNSPSC 72151204 HVAC ventilation and duct work construction service is a Commodity code that describes the installation, repair, and replacement of heating, ventilation, air-conditioning systems, ductwork, and related controls in institutional, municipal, and utility facilities. State and local governments buy under this code to upgrade, replace, and maintain HVAC infrastructure at schools, administrative buildings, detention facilities, transit stations, utility operations centers, and other public properties. The recent opportunities show a mixed issuing-body profile: school districts (Marion County Public Schools, Austin Independent School District, Greenville Public Schools, Douglas County Schools, Effingham County School District) and municipal/county departments (Orange County Sheriff-Coroner, City of Wichita, Kissimmee Utility Authority, City of DeBary, Dougherty County, Henry County, Habersham County, Greater Hartford Transit District, Greenville Public Schools, Fort Valley State University, Sacramento County, Florida Department of Transportation) dominate the activity. Utilities and special-purpose districts (Kissimmee Utility Authority, Greater Hartford Transit District, Georgia State University) round out the mix. The scope of work ranges from single-site system replacements to multi-facility maintenance contracts, terminal-unit retrofits, chiller rebuild and cooling tower installation, ductwork repair and cleaning, and design-build facility renovations that include HVAC as a component. Representative recent opportunities include the City of Wichita's RFB 260258 for HVAC replacement at thirteen residential sites (bid due October 30, 2026, Davis-Bacon subject, $100 per day liquidated damages), the City of Albany's RFP #27-031 for Dougherty County Jail HVAC chiller rebuild and cooling tower installation (proposals due November 13, 2026, mandatory pre-proposal conference October 21), Orange County Sheriff-Coroner's IFB-060-3145003-CF for HVAC duct repair and replacement on an as-needed basis with 24/7 emergency response (bids due November 16, 2026, five percent Orange County Local Small Business preference, three-year initial term starting February 25, 2027), and Austin Independent School District's CSP 27CSP001 for HVAC and facility improvements at Baranoff Elementary estimated at $2.166947 million (proposals due November 3, 2026).

Geographic activity concentrates in the Southeast (Florida, Georgia, South Carolina, Tennessee, North Carolina), Texas, California, and the Pacific Northwest (Washington), with scattered municipal activity in Connecticut, Colorado, Illinois, and Michigan. Florida and Georgia show the heaviest recent posting density, driven by utility authority and county school district procurement. Capital facilities upgrades and aging infrastructure replacement dominate the current market, with many solicitations tied to multi-year facility improvement programs or deferred-maintenance budgets. Prevailing wage requirements appear in several recent opportunities (Wichita, Lompoc Library, Sacramento County, Fort Valley State University), signaling federal or state grant funding constraints. Set-asides and local-vendor preferences are common: Orange County Sheriff applies a five percent Small Business and DVBE preference; Henry County applies local-vendor privilege; Dougherty County encourages local bidders with tie-bid preference; and several school districts and public works projects note small business and minority/women-owned business encouragement. Design services procurement (Marion County Public Schools RFQ 26-103 for Belleview Middle School HVAC design, due February 26, 2026, and South Dakota State University SOI for Grove Hall HVAC and roof design, due October 29, 2026) appears alongside construction and service contracts, indicating steady demand for engineering and architectural support. Multi-year maintenance and repair contracts (Henry County RFP 27-11 for annual HVAC maintenance covering approximately 100 units, initial one-year term with two renewal options; Town of Parker RFP for preventive maintenance and repair across 46 assets, renewable for four additional one-year periods; City of Huntsville IFB 27-04 for as-needed HVAC services with four one-year renewals through September 30, 2031) signal recurring procurement activity and opportunity for long-term vendor relationships.
