1. Compressor & Oil System Assessment
- Perform detailed oil analysis for moisture, acidity, and contaminants.
- Check compressor alignment, shaft seals, and coupling integrity.
- Measure and log oil pressure differential during operation.
2. Refrigerant System Inspection
- Verify refrigerant charge levels and inspect for any signs of leaks.
- Check sight glasses for bubbles or foam indicating refrigerant issues.
- Perform superheat and subcooling checks for optimization.
3. Electrical Systems Testing
- Inspect electrical terminals and tighten connections as needed.
- Test contactors, relays, and circuit breakers for proper operation.
- Review motor insulation resistance and meg-ohm test results.
4. Heat Exchanger & Water System Check
- Inspect evaporator and condenser tubes for fouling or scale buildup.
- Verify flow rates and pressure drops across heat exchangers.
- Ensure proper operation of water pumps and flow switches.
5. Overall System Performance Analysis
- Conduct full load test under standard operating conditions.
- Analyze energy efficiency ratios and performance indicators.
- Document findings and recommend corrective actions if needed.
