The City of Wilmington is seeking a qualified contractor to provide a comprehensive, city‑wide HVAC preventative‑maintenance and repair program for 21 municipal buildings over a three‑year base period, with two optional one‑year extensions. Services include quarterly walkthroughs, filter changes, seasonal start‑up/run inspections, annual coil cleanings, emergency 24‑hour response, and repair/replacement of failed or worn moving parts (with prior City approval). The contractor must supply all labor, materials, tools, vehicles, and qualified staff, maintain detailed proof‑of‑work reports, and meet stringent response times (on‑site within 2 hours). The contract is structured as a fixed‑monthly rate, with monthly invoicing and payment within ~30 days. Minimum staffing requirements are four full‑time journeymen, at least two of whom must be master‑level technicians. The solicitation includes an “Exceptions to Services” page for vendors to disclose any equipment categories they cannot service.
