Commercial Centrifugal Chiller Repair in Glendale — AC PRO Specialists

Your centrifugal chiller is the heart of your cooling plant. When it underperforms, utility costs spike, comfort drops, and mission‑critical operations are at risk. Our Commercial Centrifugal Chiller Repair service for AC PRO systems in Glendale is engineered to restore stability, efficiency, and capacity—without guesswork.

What we repair and optimize

• Surge and stall diagnostics, root‑cause correction, and control strategy adjustments
• Vibration issues: alignment checks, impeller inspection, and precision balancing
• Oil system problems: oil analysis, moisture/acid testing, and separator performance
• Refrigerant leaks: pinpoint detection, compliant repairs, evacuation, and recharging
• Heat‑exchanger performance: tube brushing, chemical cleaning, and eddy current testing
• Controls and sensors: recalibration, loop tuning, and sequencing optimization
• Drive and starter issues: soft‑starter/VFD inspections, ramp tuning, and protections
• Capacity drift: guide vane calibration, setpoint strategy, and load matching

We apply a rigorous, engineering‑grade process tailored to AC PRO centrifugal chillers and compatible systems. You get a clear plan, test data before/after, and improvements you can validate on trend logs.

Our engineering DNA

#1 AC Guys is a fourth‑generation family business with 80+ years of engineering expertise. Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). That foundation shows in our disciplined commissioning practices, documentation, and commitment to verifiable performance. We are built for big, complex commercial projects where details matter.

Diagnostics that cut downtime

• Baseline assessment: operating conditions, load profile, and recent alarms
• Performance testing: approach temperatures, kW/ton, lift, and pressure ratios
• Vibration analysis: trending, resonance checks, and mechanical integrity
• Oil and refrigerant lab tests: contamination, moisture, and acid levels
• Thermal inspection: heat‑exchanger health and flow distribution
• Controls review: PID tuning, sensor calibration, and safety interlocks

Instead of swapping parts on hunches, we diagnose systemically, then repair precisely. That’s how we shorten outages and extend asset life.

Energy and reliability upgrades

Beyond repair, we fine‑tune AC PRO chillers for stable low‑lift operation and seasonal efficiency. Strategies include optimized setpoints, improved condenser water control, guide‑vane sequencing, and drive tuning for smoother starts and fewer nuisance trips. Where appropriate, we plan tube cleaning schedules and water‑treatment coordination to protect long‑term performance.

Healthy air is our mission

Healthy buildings start with stable plants. By restoring chiller capacity and control accuracy, downstream AHUs and terminal units receive the right temperatures and flows—supporting cleaner, healthier indoor air. Healthy air means a healthier life, and every repair we make supports that mission.
