We are seeking a highly experienced and technically proficient Senior Chiller Maintenance Technician to lead maintenance, troubleshooting, and performance optimization of large-scale chiller systems within a power plant environment. This role is suited for experts who bring in-depth knowledge of centrifugal and screw chillers, advanced HVAC/R diagnostics, and supervisory capability to ensure uninterrupted cooling system reliability, regulatory compliance, and energy efficiency across plant facilities.
Lead and coordinate chiller maintenance schedules, emergency repairs, and system overhauls.
Supervise junior and mid-level technicians, assign tasks, and ensure quality workmanship.
Provide technical guidance, training, and mentoring to less experienced team members.
Diagnose complex mechanical, electrical, and control system issues in chiller equipment (centrifugal, screw, scroll types) and associated components (cooling towers, pumps, condensers).
Use advanced tools (e.g., ultrasonic leak detectors, refrigerant analyzers, thermal cameras) to identify faults and inefficiencies.
Interface with BMS/DDC/SCADA systems for system monitoring, fault tracing, and parameter optimization.
Evaluate chiller system performance trends and implement operational improvements.
Recommend retrofits or upgrades such as VFD integration, sensor replacement, or refrigerant conversion to enhance system reliability and energy efficiency.
Collaborate with plant engineers and energy managers on HVAC optimization initiatives and chilled water balancing.
Ensure adherence to ASHRAE, EPA, ISO 50001, and internal compliance standards.
Maintain comprehensive logs for refrigerant usage, component replacement, test results, and inspection reports.
Support internal and external audits by preparing system documentation and maintenance records.
Coordinate with mechanical, electrical, and controls teams during plant shutdowns, new installations, or retro-commissioning.
Participate in system design reviews and provide input on equipment selection, layout, and maintenance access considerations.
Assist with procurement decisions for tools, spares, and chiller system upgrades.
Lead high-complexity chiller maintenance and fault resolution
Optimize chiller performance for energy and operational efficiency
Ensure full compliance with safety, refrigerant, and HVAC standards
Provide team supervision and technical mentoring
Act as the subject matter expert for chilled water systems in power plant settings
