NIGP 03502: Air Conditioning Units, Aircraft (for Cooling Interiors While at the Gate)

NIGP 03502 Air Conditioning Units, Aircraft (For Cooling Interiors While At The Gate), an Item code, encompasses replacement and modernization of centralized pre-conditioned air systems, cooling towers, chillers, and room-level air conditioning infrastructure at airport terminals, school facilities, and municipal buildings. State and local governments procure under this code for HVAC system upgrades that serve both aircraft gate operations and broader facility cooling needs, typically bundled with mechanical, electrical, plumbing, and life-safety system improvements. Issuing bodies include city aviation departments, school districts, and municipal public works agencies; the City of Atlanta Department of Aviation and Pinellas County School District appear as active repeat buyers in recent months. Work solicited ranges from major mechanical equipment replacement at high-traffic airport concourses to distributed cooling infrastructure across school district campuses, with contracts often requiring licensed mechanical, electrical, and plumbing contractors and substantial financial capability and past-performance documentation.
