About NIGP 05504
NIGP 05504 Air Conditioners and Parts, an Item code, represents the procurement of HVAC equipment, components, and related services across state and local facilities—from replacement units and compressors to system upgrades, water testing, and installation work. Recent solicitations show state and local governments buying complete HVAC units and motors on an as-needed basis, overhauling and modernizing existing systems in vehicles and buildings, performing water treatment and testing on hydronic systems, and contracting for removal and installation of jet bridge-mounted and pre-conditioned air units at airports. The buying community spans school districts, county departments, state transportation agencies, transit authorities, and municipal aviation departments, with repeat activity from county purchasing offices and specialized state agencies managing large facility portfolios.
Recent opportunities appear across California, Texas, Nevada, Illinois, Florida, and Missouri, with particular density in California (Caltrans and county projects), school districts nationwide (Clark County School District in Nevada, School District U-46 in Illinois, and Rockwood School District in Missouri), and transportation authorities (Utah Transit Authority and City of Dallas Aviation). Representative solicitations include the Clark County School District's RFB for HVAC Units, Motors, Compressors and Parts (due April 16, 2026) on an as-needed supply basis; the Utah Transit Authority's RFP for Bombardier Bi-Level HVAC Unit Overhaul and Modernization (due May 25, 2026) for 82 units across 38 commuter rail vehicles; Caltrans' IFB for water testing services on HVAC hydronic systems across nine California counties (due June 30, 2026) with mandatory 3 percent DVBE participation and 25 percent SB participation goals; and the City of Dallas Department of Aviation's RFB for removal and installation of 20 pre-conditioned air HVAC units at Dallas Love Field (due February 20, 2026). School District U-46's HVAC Replacement at Tefft Middle School (due February 25, 2026) represents the capital-intensive replacement end of the code, with a $450,000 general allowance and two-phase completion through 2027.
