NIGP 55723: Cooling System Parts and Accessories

NIGP 55723 Cooling System Parts and Accessories is an Item code under which state and local governments procure individual cooling-system components and assemblies—radiators, chillers, hoses, controllers, fuse holders, and related repair parts—along with maintenance, repair, and replacement services for cooling infrastructure at facilities and vehicle fleets. The issuing bodies span county transit authorities, county facilities management, school districts, and cities; Dallas County, Pasco County, Monroe County, and Hillsborough County Public Schools appear repeatedly in recent solicitations. Scope includes everything from discrete parts (radiator isolators, silicone elbows, wire harnesses, hose assemblies) to major equipment replacement (275-ton air-cooled chillers) and recurring maintenance contracts covering multiple locations. School bus air-conditioning repair and maintenance is a active segment, with Hillsborough County Public Schools requiring contractors to service both R-134a and R-1234yf refrigerant systems on Type A and Type C buses, with a Small Business Encouragement Program participation floor of 20 percent of eligible expenditures.

Recent geographic activity concentrates in Texas (Dallas County, Dallas Area Rapid Transit Authority), Florida (Pasco County, Monroe County, Broward County, City of Ocala, Hillsborough County), and Missouri (Parkway School District). Representative solicitations include Pasco County Board of County Commissioners' cooling-tower replacement (Jaggaer-posted, due December 16, 2026); City of Ocala's 275-ton air-cooled chiller supply-and-install ITB with mandatory pre-bid November 10, 2025 and final bid December 2, 2025; Hillsborough County Public Schools' school-bus A/C maintenance RFP with SBEP subcontracting requirements (due August 7, 2026); Monroe County's countywide chiller maintenance RFP across multiple locations (due June 17, 2026, 100-point scoring on costs, qualifications, and staff); and Dallas County's repeated part-specific IFBs (fuse holders, hose assemblies, radiators, wire harnesses) with tight three-to-five-day response windows. Broward County Transportation Department issued a Cummins engine and chassis repair solicitation for the BCT bus fleet with FTA compliance requirements (due June 1, 2026). Parkway School District in Missouri solicited bus and vehicle OEM parts and service on a blanket purchase-order basis (due May 19, 2026).
