Commercial Centrifugal Chiller Repair in Calabasas

When a centrifugal chiller goes down, every minute counts. #1 AC Guys is the family‑owned, Los Angeles–based engineering team Calabasas businesses call for rapid, reliable, and measurable repairs. Our mission is healthy indoor air and stable comfort, delivered through disciplined diagnostics and repairs that restore capacity, efficiency, and compliance.

What we repair and optimize

• Advanced diagnostics: vibration analysis, surge/stall investigation, thermography, controls fault tracing
• Mechanical: impeller inspection and balancing, bearings and seals, alignment, tube cleaning and eddy‑current testing
• Refrigeration circuit: leak detection, deep vacuum dehydration, refrigerant charging/retrofit, subcooling/superheat tuning
• Lubrication system: oil analysis (acidity, moisture, metals), filter/drier replacement, oil pump and heater issues
• Electrical and drives: VFD/soft starter troubleshooting, power quality, contactors, sensors, safeties
• Controls and BAS: setpoint logic, staging, resets, BACnet integration, trend verification
• Performance: kW/ton optimization, condenser water reset strategy, approach temperature improvements

Our engineered workflow

We don’t just swap parts—we solve root cause. Expect a clear, step‑by‑step plan that minimizes downtime and prevents repeat failures.

• Stabilize and assess: safety lockout, operating history review, alarm and trend download
• Test and measure: pressures, temps, flows, vibration, oil/refrigerant lab tests as needed
• Isolate faults: mechanical vs. electrical vs. controls vs. water‑side issues
• Repair/replace: OEM‑grade procedures with quality components sourced through AC PRO for speed and reliability
• Recommission: verify flows, approach, kW/ton, and protection setpoints; document results
• Prevent: deliver a maintenance and monitoring plan matched to your load profile

When to call us

• Rising condenser approach, frequent surging, or nuisance trips
• Abnormal vibration/noise, oil discoloration, or metal in filters
• Poor pull‑down, rising energy bills, or unstable supply water temperature
• VFD faults, starter issues, sensor drift, or BAS communication errors

Parts, brands, and training

To accelerate repairs without compromising quality, we source components and materials through AC PRO’s regional supply network. Our multi‑brand service capability is reinforced by factory training completed at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This background strengthens our refrigeration, controls, and commissioning practices on complex commercial systems.

Preventive and predictive care

• Seasonal start‑ups and layups, strainers and water‑treatment coordination
• Tube cleaning and eddy‑current testing to protect heat‑transfer efficiency
• Oil and refrigerant trend analysis to catch faults early
• VFD health checks, sensor calibration, and setpoint optimization
• Remote monitoring options for alarms and performance drift
