NIGP 03108: Air Curtains

NIGP 03108 Air Curtains, an Item code, covers preventative maintenance, repair, and optimization services for boiler and chiller systems at public facilities. State and local governments use this code to solicit work on heating and cooling equipment across administrative, transit, and facility-management portfolios. The scope includes routine maintenance, emergency repairs, equipment upgrades, and installations on existing chillers and boilers from manufacturers such as Trane, Pulse, Aalon, Carrier, and Lochinvar. Issuing bodies include city transit authorities, county governments, and other municipal facilities departments responsible for building-systems management. The selected vendors typically must hold manufacturer certifications and maintain access to proprietary parts and service documentation specific to each equipment line.

The City of Charlotte, through its transit authority CATS, posted an RFP (solicitation 26920271769) on September 22, 2026, for preventative maintenance and repair services on boiler and chiller systems at CATS facilities, with proposals due October 15, 2026. Recent activity is concentrated in the Southeast, with Charlotte representing current procurement momentum in this space. The code sees intermittent solicitation from transit authorities and municipal facilities departments; the frequency and volume of opportunities remain limited based on available records.
