What our commercial centrifugal chiller maintenance includes

• Performance benchmarking: entering/leaving water temps, approach, kW/ton, lift, and capacity verification against design.
• Oil and refrigerant health: acid number, moisture, metals, and refrigerant purity checks with trend analysis.
• Tubes and heat transfer: eddy current testing, mechanical tube brushing, condenser and evaporator cleaning, scale mitigation.
• Vibration and alignment: bearing condition checks, vibration trending, shaft inspection, starter and VFD calibration.
• Controls and safety: sensor calibration, setpoint optimization, surge avoidance strategies, safeties and interlocks testing.
• Purge and sealing: purge unit inspection, leak detection per EPA 608, gasket and insulation integrity.
• Hydronics: flow, delta-T, strainers, water treatment verification, tower interface and condenser water quality review.
• Seasonal readiness: startup/shutdown procedures, freeze protection, emergency response planning.
• Documentation: photo-rich reports with prioritized recommendations and ROI-driven energy insights.

Every task is executed with traceable measurements and clear pass/fail criteria, giving facility teams confidence and an actionable roadmap to reliability and efficiency.
