Master Facilities Technician – HVAC

The Master Facilities Technician – HVAC is responsible for the operation, maintenance, troubleshooting, and repair of HVAC and facility systems supporting a semiconductor manufacturing environment. This role ensures critical facility systems operate safely, reliably, and within the environmental conditions required for semiconductor manufacturing and cleanroom operations.

The technician will work with complex HVAC, chilled water, heating, cooling, ventilation, and building management systems while responding to equipment failures and supporting preventive and predictive maintenance programs.

• Operate, maintain, troubleshoot, and repair HVAC and mechanical facility systems, including air handling units, rooftop units, exhaust systems, pumps, fans, chillers, boilers, cooling towers, and associated equipment.
• Maintain HVAC systems supporting clean rooms and controlled manufacturing environments, including temperature, humidity, pressure, airflow, and air-quality requirements.
• Monitor and respond to alarms and equipment conditions through Building Management Systems (BMS)/Energy Management Systems (EMS).
• Perform preventive and predictive maintenance on HVAC and mechanical equipment to maximize equipment reliability and minimize downtime.
• Troubleshoot electrical, mechanical, pneumatic, and control-system issues associated with HVAC equipment.
• Diagnose and repair issues involving motors, belts, bearings, dampers, valves, actuators, sensors, VFDs, compressors, pumps, and control systems.
• Support operation and maintenance of chilled-water and hot-water systems used throughout the facility.
• Perform inspections, equipment rounds, readings, and operational checks and document findings.
• Respond to facility and equipment emergencies and take appropriate action to protect personnel, equipment, product, and manufacturing operations.
• Work closely with Facilities Engineers, Manufacturing, Equipment Engineering, and other technical teams to resolve facility-related issues.
• Assist with equipment installations, upgrades, modifications, and commissioning activities.
• Maintain accurate maintenance records, work orders, equipment history, and documentation using a computerized maintenance management system (CMMS).
• Follow all applicable safety, environmental, hazardous energy/LOTO, cleanroom, and semiconductor manufacturing procedures.
• Maintain compliance with company policies, OSHA requirements, applicable codes, and environmental regulations.
• Work with contractors and vendors during equipment installation, service, inspections, and repairs.
• Provide technical guidance and mentorship to less-experienced Facilities Technicians.
• Participate in continuous improvement initiatives focused on equipment reliability, energy efficiency, cost reduction, and facility uptime.
• Participate in an on-call, weekend, or rotating shift schedule as required.
