Inspect expansion valves, solenoid valves, filter driers, sight glasses, pressure switches, and refrigerant piping. Check refrigerant leaks and arrange safe repairs using approved procedures. Monitor refrigerant charge and system performance in accordance with manufacturer specifications. Inspect compressor oil levels, oil condition, lubrication systems, and operating temperatures. Investigate high-pressure trips, low-pressure trips, compressor overheating, frosting, and inadequate cooling. Maintain required temperature conditions for storage and process applications. Follow applicable requirements for refrigerant recovery, handling, storage, and disposal. C. Chiller and Cooling Tower Operations Monitor water-cooled and air-cooled chillers, where installed. Record chilled water supply and return temperatures. Monitor condenser water temperatures, water flow, operating pressures, and compressor current. Inspect chilled water pumps, condenser water pumps, strainers, valves, and associated piping. Check cooling tower fans, motors, belts, nozzles, fill media, and water levels. Coordinate water treatment, descaling, tube cleaning, and periodic inspection. Identify abnormal operating conditions and coordinate corrective action with specialist service providers. Track equipment performance and report deterioration in cooling capacity or efficiency. D. Preventive Maintenance (PM) Prepare and execute preventive maintenance schedules for HVAC and refrigeration equipment. Conduct daily, weekly, monthly, quarterly, and annual inspections as applicable. Maintain preventive maintenance checklists and equipment history records. Ensure timely servicing of compressors, motors, pumps, fans, filters, coils, and electrical components. Coordinate annual maintenance contracts (AMCs) and OEM service visits. Follow up on pending maintenance activities and ensure timely closure. Identify recurring faults and recommend permanent corrective actions. Maintain critical spare parts and consumables inventory. E. Breakdown Maintenance and Troubleshooting Respond to equipment breakdowns and cooling complaints. Diagnose electrical, mechanical, refrigeration, and control-system faults. Troubleshoot compressor failures, refrigerant leaks, blocked filters, faulty sensors, motor failures, and control circuit problems. Check electrical connections, contactors, relays, overloads, circuit breakers, and control panels. Coordinate with electrical, instrumentation, production, and facility teams. Restore equipment operation safely and minimize downtime. Record the root cause, corrective action, parts replaced, and downtime for each major breakdown. Recommend measures to prevent repeated failures. F. Installation and Commissioning Coordinate installation of new air conditioning and refrigeration equipment. Review equipment specifications, installation drawings, and manufacturer recommendations. Verify equipment positioning, mounting, piping, insulation, drainage, and electrical connections. Coordinate refrigerant piping pressure tests, leak tests, evacuation, and charging using approved procedures. Verify electrical supply, earthing, protection devices, and control wiring. Conduct commissioning checks and record baseline operating parameters. Ensure that equipment handover documentation, operating manuals, and warranties are available. G. Electrical and Control Systems Inspect electrical panels, motor starters, contactors, overload relays, and control circuits. Monitor voltage, current, phase imbalance, and motor operating conditions. Check thermostats, pressure switches, temperature sensors, and safety interlocks. Assist with troubleshooting PLC-based controls, BMS systems, and HVAC automation where applicable. Ensure that equipment safety trips and protective devices function correctly. Coordinate electrical repairs with authorized personnel. Follow lockout/tagout and electrical isolation procedures before maintenance. H. Energy Efficiency and Performance Improvement Monitor electricity consumption and operating hours of HVAC and refrigeration equipment. Identify opportunities to reduce energy consumption without compromising required temperatures or operating conditions. Maintain appropriate temperature set points and operating schedules. Check filter cleanliness, heat exchanger condition, airflow, and water flow. Monitor compressor loading, short cycling, refrigerant leakage, and other efficiency-related issues. Recommend improvements such as optimized operating schedules, efficient motors, variable-frequency drives, and control-system upgrades where justified. Prepare periodic reports on energy consumption, equipment performance, and maintenance costs. I. Safety and Environmental Compliance Follow company EHS policies and applicable statutory requirements. Use appropriate personal protective equipment (PPE). Follow safe work procedures for electrical maintenance, working at height, confined spaces, and hot work where applicable. Ensure proper isolation of equipment before maintenance. Handle refrigerants in accordance with applicable safety and environmental requirements. Prevent uncontrolled refrigerant release and ensure appropriate recovery practices. Maintain good housekeeping in plant rooms, refrigeration areas, and equipment spaces. Report unsafe conditions, near misses, and incidents promptly. Ensure that only trained and authorized personnel perform specialized or high-risk work. J. Documentation and Reporting Maintain equipment registers and asset identification records. Prepare daily equipment operating logs and maintenance reports. Maintain preventive maintenance schedules and breakdown history. Record temperature, pressure, current, voltage, and other relevant operating parameters. Update spare parts consumption and inventory records.
