Commercial Air Chiller Repair in Anaheim — AC PRO Systems

Engineered Expertise for Complex Commercial Chillers

#1 AC Guys is a fourth-generation family business built by engineers. With 80+ years of engineering experience, we approach every commercial air chiller repair with disciplined diagnostics and transparent recommendations. Our technicians have completed factory training with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), enabling rigorous service practices on modern chiller technologies used throughout Southern California.

We service AC PRO supplied chiller systems and associated components across Anaheim and Orange County, resolving issues in air-cooled and water-cooled chillers, packaged and split configurations, and integrated controls. From retail and hospitality to healthcare, education, industrial, and mixed-use facilities, we are trusted for fast, accurate problem-solving on small to large, simple to highly complex projects.

Systems and Components We Service

• Air-cooled chillers: scroll, screw, variable-speed, heat-recovery configurations
• Water-cooled chillers and condenser water systems, pumps, strainers, towers (coordination)
• Compressors, VFDs, condenser fan motors, EC fans, pumps, actuators, and valves
• Electronic expansion valves (EEV), TXV, sensors, transducers, and flow switches
• Control boards, BAS integrations, setpoint and sequence optimization
• Coils, heat exchangers, refrigerant circuits, oil management, and leak remediation

Our Commercial Air Chiller Repair Process

• Intake and site assessment: review alarms, operating history, and application needs
• Measured diagnostics: pressures, superheat/subcool, delta T, electrical, airflow/waterflow
• Root-cause analysis: controls logic, sensor accuracy, load profile, and environmental factors
• Action plan: prioritized repair options with parts availability and downtime estimates
• Precision repair: OEM-grade parts and procedures aligned to manufacturer standards
• Verification: performance testing, re-commissioning steps, and documented results

This approach restores reliability, stabilizes capacity, and protects efficiency so your Anaheim operation runs smoothly.

Common Anaheim Chiller Problems We Fix

• Low capacity or low delta T due to fouled coils, airflow issues, or improper charge
• Refrigerant leaks (e.g., R410A, R134a) and contamination, including non-condensables
• Compressor trips, VFD faults, high head pressure, or freeze protection events
• Control board errors, sensor drift, staging and sequencing problems
• Pump or flow switch faults, air in hydronic loops, cavitation, and imbalance
• Oil return issues, poor superheat/subcool control, and EEV/TXV malfunctions

We do more than clear alarms. We correct underlying causes to extend equipment life and stabilize energy costs.

Performance Upgrades and Preventive Care

Proactive service reduces outages and improves comfort. We tailor maintenance plans and targeted retrofits for AC PRO serviced systems to match your building and budget.

• Coil restoration, refrigerant circuit optimization, and verified charge
• VFD tuning, EC fan upgrades, and demand-based control strategies
• BAS integration, sensor calibration, and sequence of operation improvements
• Water-side coordination: treatment partners, strainers, tower service, and balancing
• Energy optimization, heat-recovery strategies, and recommissioning

The result: fewer breakdowns, better IAQ, and measurable efficiency gains.
