What We Repair and Optimize

• Compressors (scroll, screw, centrifugal), oil management, soft starters, and VFDs.
• Evaporators and condensers, tube cleaning and descaling, coil restoration.
• Refrigerant circuits: precision leak detection, evacuation, and charging to spec (superheat/subcool verification).
• Controls and sensors: expansion valves, EEVs, transducers, safeties, and BMS setpoint tuning.
• Hydronic components: pumps, strainers, valves, cooling‑tower interfaces, flow and delta‑T optimization.
• Electrical: contactors, relays, boards, wiring integrity, and megger testing where appropriate.

Signs Your Chiller Needs Service

• Rising energy use per ton, longer runtimes, or nuisance trips.
• High head pressure, low delta‑T, or inadequate supply‑air temperature.
• Unusual vibration or noise; oil staining; refrigerant or chemical odors.
• Scale, fouling, corrosion, or salt‑air related coil deterioration.
• Comfort complaints, hot spots, or temperature swings across floors or critical rooms.

Our Proven Repair Process

1. Assessment: Discovery call and on‑site evaluation to understand loads, history, alarms, and operating conditions.
2. Root‑Cause Diagnostics: Trending and logs, pressure/temperature mapping, superheat/subcool checks, oil analysis, vibration and electrical testing.
3. Clear Plan: Repair options with timelines and budget ranges—repair vs. rebuild vs. replace guidance when lifecycle economics warrant it.
4. Precision Repair: OEM‑level practices, controls calibration, leak resolution, and performance verification under load.
5. Performance Report: Before/after benchmarks, recommendations to reduce kW/ton, and maintenance strategies to prevent repeat failures.
