NIGP 76502: Air Conditioners, Heaters and Ventilators for Heavy Equipment

NIGP Item 76502 Air Conditioners, Heaters and Ventilators for Heavy Equipment encompasses chiller maintenance, service, and installation work that state and local governments solicit across facilities management and institutional infrastructure projects. Recent opportunities reveal that the code captures both routine and emergency HVAC service contracts on building systems and one-time mechanical upgrades tied to school facility renovations. Monroe County Board of County Commissioners in Florida posted RFP633 in May 2026 seeking countywide chiller maintenance and service at multiple locations, requiring a licensed HVAC contractor with Type III or Universal Certification to deliver routine repair, preventative maintenance, and emergency services on county chillers across the Key West to Key Largo corridor, with proposals due June 17, 2026. The City of Norwalk, Norwalk Public Schools in Connecticut issued bid solicitation 4513 in April 2026 for mechanical and electrical upgrades at Wolfpit Elementary School, including removal of 21 existing window AC units, installation of 31 new window units and five split-system air conditioning units with associated piping and insulation, with sealed bids due May 15, 2026. Issuing bodies under this code span county facilities departments, municipal school districts, and other jurisdictional maintenance operations seeking either multi-year service retainers or discrete capital equipment installation projects.

Activity concentrates in Florida and California based on recent filings, with secondary presence in Connecticut and broader geographic reach through cooperative purchasing vehicles. Monroe County and the City of Norwalk represent the two most recent substantive opportunities in the source block. The code does not see high-volume solicitation activity in the sample provided—the two named opportunities span May and April 2026, suggesting moderate rather than frequent purchasing cycles. Pursuit feasibility depends on certification and licensing requirements; Monroe County explicitly mandates Type III or Universal HVAC certification and business tax registration, while the Norwalk project requires standard contractor bonding and insurance but does not specify trade certification in the available documentation. Neither opportunity discloses incumbent vendors or set-aside designations, though both operate within standard state and local compliance frameworks (prevailing wage applies to the school project; general liability and workers' compensation insurance required for the county chiller contract).
