The anticipated services to be performed by the selected firm may include, but not be limited to, quarterly and semi-annual preventive maintenance, testing and inspection, and seasonal changeover services for the equipment listed on Exhibit B attached hereto. The intent of the preventative maintenance program (the “Program”) is to maintain each piece of equipment in accordance with manufacturer’s specifications and industry standard practices. The Program should be comprehensive and include all work necessary to verify and ensure proper operation of the systems as well as seasonal changeover of the building systems from cooling (or non-heating) to heating modes where necessary. The Program includes: • filter changes at least quarterly for roof top units (MERV 8); filter changes at least twice a year for VAVs; belt changes at the manufacturer recommended intervals; coil brush down; lubrication of motor bearings, fan motors; and changing oil and dampers where applicable; • adjusting and fine-tuning capacity control modules, belt tension, gas burners, starter transfer timers, and compressor cylinder unloaders; • inspections and cleaning condenser/evaporator coils, chilled water coils, condensate drains, pans, fans, coils, motors and boiler combustion chambers; • inspections and testing of control system components to ensure control devices are within industry tolerances, determine equipment status and identify necessary repairs and operating per design specifications; • inspections and testing of control calibration and adjustment-of refrigeration controls, pressure controls, operating controls and safety controls. • testing and checking operating refrigerant pressures; reversing valve operations on heat pumps; voltages and amperages; belts and belt tension; drive couplings; proper control sequencing; electrical connections; rotation; condensate tray for proper drainage; contactors; and starters. • perform checks on the overall operating performance of thermostat operation and heating and cooling systems
