About this file
This is a Heat Pump Unit Checklist document associated with a one-year HVAC repair and preventive maintenance contract for the State of Maryland's SHA Centreville facility located on the Eastern Shore. The checklist outlines the quarterly and seasonal maintenance requirements for heat pump units at the facility. Quarterly service tasks include replacing air filters, checking fan belts for tension and wear, inspecting damper linkage, verifying refrigerant levels and checking for leaks, inspecting access panels, confirming static pressure control sensor operation, examining ductwork and insulation for leakage, cleaning drain pans, inspecting condensation lines, checking for vibration and unusual noises, inspecting moisture eliminators and outside air hoods, examining flexible duct connections, and inspecting coils for damage and cleanliness. Seasonal maintenance tasks include verifying the sequence of operation, cleaning fan housing and blower wheels, sealing air leaks, cleaning screens, verifying safety and auxiliary controls, measuring compressor motor ground resistance, testing interlock controls, inspecting and tightening electrical connections, lubricating bearings and dampers, cleaning motor intake screens, and inspecting structural equipment supports for corrosion and damage.
The checklist serves as a performance standard and inspection guide for service technicians contracted to maintain the facility's HVAC systems. Each service visit requires documentation of the unit being serviced, the facility location, the service technician performing the work, and the date of service. The document does not specify pricing terms, set-asides, incumbent contractors, contract renewal options, or funding sources; however, it establishes the technical scope and quality standards that the selected contractor must meet throughout the contract term.
