Core Responsibilities:

Installation:

• Carry out on-site installation of high temperature heat pump units, including mechanical, hydraulic, electrical, and refrigerant-circuit connections, as per design drawings and P&IDs.
• Perform pre-commissioning checks: pressure testing, vacuum/dehydration, refrigerant charging, and leak detection in line with F-Gas/refrigerant handling regulations.
• Commission compressors, evaporators, condensers, controls, and BMS/PLC integration, and validate performance against design parameters (COP, capacity, flow/temperature).
• Coordinate with civil, electrical, and piping contractors at site to ensure installation readiness and resolve interface issues.
• Hand over commissioned systems to the customer with complete documentation, test records, and operator training.

Service & Maintenance

• Execute scheduled preventive maintenance (PM) visits as per the maintenance calendar and OEM guidelines.
• Diagnose and rectify breakdowns on refrigeration circuits, compressors, controls, sensors, and auxiliary equipment, minimizing downtime.
• Perform refrigerant top-up/recovery, oil analysis, and component replacement (compressors, valves, sensors, heat exchangers) as required.
• Support performance optimization visits, identifying opportunities to improve system efficiency (COP) and reliability.
• Manage spare parts requirements for service visits, including forecasting and inventory coordination with the service planning team.

Troubleshooting & Technical Support

• Provide remote and on-site technical troubleshooting support for control systems, refrigerant circuits, and electrical faults.
• Analyze recurring failure patterns and elevate design or quality issues to Engineering/R&D with root-cause data.
• Support warranty claim investigations with technical evidence, failure analysis, and corrective action recommendations.

Documentation & Reporting

• Prepare and submit installation, commissioning, and service reports within defined timelines using the company's service management/CRM system.
• Maintain accurate site records: test certificates, refrigerant logs, PTW/permit records, and customer sign-offs.
• Update job status, parts consumption, and time logs for accurate billing and service cost tracking.

Safety, Health & Compliance

• Strictly adhere to Permit-to-Work (PTW), Lock-Out-Tag-Out (LOTO), working-at-height, and confined-space safety protocols at customer sites.
• Handle refrigerants in compliance with applicable environmental and F-Gas/ozone-depletion regulations; hold or work toward relevant refrigerant handling certification.
• Use appropriate PPE and follow customer-specific EHS requirements at all times.
• Report near-misses, incidents, and unsafe conditions promptly as per company EHS procedures.

Customer Interaction & Training

• Act as the technical face of the company at customer sites, ensuring professional communication and timely issue resolution.

• Support the sales/service team with technical inputs during site surveys, feasibility assessments, and service contract renewals.

Qualification:

• Diploma/B.Tech/B.E. in Mechanical, Electrical, Refrigeration & Air Conditioning, or a related engineering discipline.
• 3-5 years of hands‑on experience in installation, commissioning, or service of heat pumps, chillers, industrial refrigeration, Industrial Chillers or Vam Chillers; experience with high temperature heat pumps or industrial process heating is a strong advantage.
• Working knowledge of refrigeration cycles, compressors (screw/scroll/reciprocating), heat exchangers, and refrigerants (including low-GWP/natural refrigerants such as ammonia, CO2, or propane, where applicable).
• Exposure to BMS/PLC‑based controls, sensors, and instrumentation used in heat pump systems.
• Willingness to travel extensively to customer sites, including domestic and (where required) international locations.
