Our commercial air chiller repair process

1. Diagnose. We start with sensor validation, refrigerant analysis, subcooling/superheat checks, and electrical testing to isolate root causes—not just symptoms.

2. Stabilize. Correct critical faults, restore oil and refrigerant balance, repair leaks, and protect compressors with proper controls settings.

3. Restore. Replace failed components, clean coils, recalibrate valves, align VFD parameters, and verify airflow and water flow setpoints.

4. Optimize. Tune staging, economizer strategies, and fan curves to reduce energy intensity and improve load following. Provide a post‑repair performance report.

Common warning signs your chiller needs service

• High head pressure, low delta‑T, or poor pull‑down times
• Short cycling, nuisance alarms, or breaker trips
• Uneven cooling across zones or process lines
• Rising energy bills or degraded part‑load efficiency
• Oil staining, refrigerant odor, or visible corrosion
• Excessive noise, vibration, or fan motor overheating

If you see any of these in Fontana, schedule Commercial Air Chiller Repair right away to protect your compressors and avoid extended downtime.
