Exhibit 1-HVAC Equipment and Task List .xlsx

This is an HVAC Equipment and Task List exhibit for a preventative maintenance contract with the Michigan Department of Transportation (MDOT) Grand Region. The document specifies equipment inventory and corresponding maintenance requirements across multiple HVAC systems. The facility contains one Lochinvar boiler requiring annual inspection of valves, piping, burner cleaning, heat exchanger disassembly and cleaning, boiler flushing, condensate drain filter changes, and low water cutoff testing. Two QMark electric unit heaters require annual cleaning and inspection. Six Mitsubishi mini-split units and six corresponding condensing units require semi-annual maintenance in April and September, including evaporator coil inspection and cleaning, filter cleaning, and mechanical and electrical system inspections. Five rooftop units manufactured by Carrier and Trane require six-month service intervals including economizer filter inspection and replacement, refrigerant component inspection, lubrication of moving parts, condenser coil cleaning, and belt inspection or replacement. Two Greenheck exhaust fans require annual cleaning, lubrication, and electrical component inspection.

The exhibit provides specific equipment identifiers including make, model, and serial numbers for all units, enabling precise tracking and maintenance documentation. The preventative maintenance schedule is organized by frequency, with annual tasks assigned to boiler, electric heaters, and exhaust fans, semi-annual tasks for mini-split units and condensing units, and six-month intervals for rooftop units. This comprehensive equipment listing and task breakdown establishes the scope of work for the MDOT Grand Region HVAC preventative maintenance contract, allowing bidders to understand the full extent of maintenance responsibilities and develop accurate cost proposals based on the specified equipment and service frequencies.
