The City of Wilmington is seeking a qualified contractor to deliver a comprehensive, city‑wide HVAC preventive‑maintenance, repair, and emergency‑response program for 21 municipal facilities over a three‑year base term, with two optional one‑year extensions. The work includes quarterly inspections, filter changes, seasonal start‑ups, coil cleanings, repairs of failed or worn moving parts (subject to prior City approval), and 24‑hour emergency service with a 2‑hour on‑site response. All labor, materials, tools, vehicles, and consumables are to be covered under a fixed‑monthly rate. The contractor must staff at least four full‑time journeymen (including two master‑level technicians), provide background checks for all personnel, and submit proof‑of‑work documentation within 48 hours of each service. The solicitation emphasizes M/WBE participation but does not impose set‑aside requirements.
