Proposal for HVAC Services -Nahata Dziil, Gap, Tsaile and Red Rock Head Start Centers

The Navajo Nation Department of Dine Education is seeking a qualified contractor to provide comprehensive HVAC services—including installation, repair, preventive maintenance, and related electrical work—for four Head Start centers located in Nahata Dziil, Gap, Tsaile, and Red Rock. Vendors must complete mandatory site visits to each center, submit a signed Site Visit Acknowledgment Form, and deliver a detailed, all‑inclusive proposal by the November 6 2026 deadline. The contract will require compliance with federal, state, Navajo Nation, and Head Start health‑and‑safety codes, and includes a 90‑day warranty period for workmanship. • Scope covers full‑service HVAC installation, upgrades, duct work, electrical circuit installation (licensed AZ/NM electricians required), and ongoing preventive/ emergency maintenance. • Mandatory site‑visit acknowledgment forms must accompany proposals; failure to include them renders the bid unresponsive. • Proposals must include all taxes (including 6 % Navajo Nation tax), liability insurance, debarment certifications, and a letter of transmittal; evaluation will weigh qualifications, technical approach, project management, and cost.
