Senior Facilities Maintenance Technician

About the Role

This is a facilities-first maintenance position supporting critical building and utility systems across three food manufacturing sites. The primary focus is keeping HVAC, boiler, compressed air, and ancillary utility systems running reliably through structured preventive maintenance and hands-on diagnostic and repair work. This person is expected to complete assigned PMs on schedule, document findings accurately in the CMMS, and escalate issues to their supervisor when work falls outside their scope. Production equipment support is a secondary but real responsibility; this person will assist the broader maintenance team when workload requires it.

Principal Duties/Responsibilities:

HVAC Systems (Primary Focus)

• Perform preventive maintenance on rooftop units and other HVAC equipment across all three sites, including scheduled roof walks, filter replacements, coil inspections, and belt/pulley checks.
• Diagnose and repair HVAC mechanical and electrical faults, including failed contactors, run capacitors, fan motors, and control boards.
• Test, replace, and calibrate transducers and pressure/temperature sensors.
• Inspect refrigerant circuits; identify and report indicators of refrigerant loss or system underperformance.
• Coordinate with BMS/controls systems where present to verify setpoints and alarm conditions.
• Document all PM completions, findings, and corrective work generated in the CMMS.

Boiler Systems

• Perform water-side PM including chemical treatment testing, blowdown procedures, and water quality documentation (conductivity, pH, hardness).
• Check gauges, sight glasses, and safety device indicators as part of routine rounds; log readings and flag abnormal conditions.
• Inspect general boiler room conditions including piping, valves, and ancillary equipment for visible leaks, corrosion, or wear.
• Maintain boiler logs accurately and consistently.
• Escalate any operational concerns, safety device anomalies, or system irregularities to supervisor or via CMMS work order.

Compressed Air Systems

• Perform PMs on air compressors including oil changes, filter replacements (inlet, oil separator, coalescing), belt inspections, and dryer checks.
• Monitor system pressure, dew point, and air quality; document trends and flag abnormal readings.
• Diagnose compressor faults including pressure regulation issues, moisture carryover, and motor or drive problems.
• Maintain drain traps, aftercoolers, and distribution system components.

Water Filtration

• Replace and document filter cartridges across site filtration systems on scheduled intervals.
• Verify pre/post differential pressure and flag abnormal flow restriction or consumption.
• Maintain change-out logs and coordinate filter supply replenishment.

Monitored Systems — Ammonia, CO2, Fire Suppression

These systems are not serviced in-house. The role requires system familiarity, alert recognition, and clear escalation practices.

• Ammonia refrigeration: understand system overview, recognize alarm conditions, and escalate to supervisor or log in CMMS immediately. No hands-on service work.
• CO2 system: monitor delivery pressure and system status; recognize low-supply or freeze events; escalate to supervisor or log in CMMS for response.
• Fire suppression: understand how the system works; read and interpret panel alerts; reset nuisance alarms and distinguish them from real fault conditio
