Commercial Chiller Repair in Anaheim

The #1 AC Guys Difference

For more than four generations, our family has built, serviced, and optimized mechanical systems that Southern California businesses rely on every day. At #1 AC Guys, commercial chiller repair is a core specialty—not a sideline. Our engineers combine 80+ years of practical engineering heritage with factory training from leading manufacturers such as Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That mix of hands‑on expertise and advanced diagnostics means you get precise repairs, faster turnarounds, and long‑term performance gains.

Fast, Accurate Diagnostics

Downtime costs money. We prioritize rapid response in Anaheim and across Orange County with technicians equipped to test thermistors and sensors, verify refrigerant charge, inspect evaporators and condensers, validate pump and fan operation, and interrogate controls and BMS integrations. Our fault isolation process targets the true root cause—whether it’s compressor issues, oil or refrigerant problems, scaling, poor water treatment, airflow blockages, failing VFDs, or control logic conflicts—so you avoid repeat failures.

What We Repair and Optimize

• Air‑cooled and water‑cooled chillers
• Scroll, screw, and centrifugal machines
• Heat exchangers, tubes, coils, and piping
• Pumps, cooling towers, VFDs, and motors
• Expansion valves, sensors, and actuators
• Controls, staging, and BMS integration
• Refrigerant leaks, retrofits, and charge optimization
• Flow balance, setpoint tuning, and efficiency upgrades

Built for Large and Complex Projects

From multi‑tenant office campuses and hotels to hospitals, process cooling, and critical environments, we excel when systems are big, intricate, or mission‑critical. We plan around your production or occupancy schedule, coordinate with facility teams and GCs, and provide clear milestones to keep your stakeholders aligned. Our mission is healthy air for healthy life—and that starts with a stable, efficient chiller plant that supports comfort, safety, and productivity.

Preventive Maintenance That Pays Back

Chillers rarely fail without warning. Our preventive programs cover tube and coil cleaning, vibration and oil analysis, water treatment guidance, refrigerant leak checks, sensor calibration, and seasonal commissioning. Expect lower energy use, fewer emergency calls, extended equipment life, and documented performance improvements that support budgeting and ESG goals.

Energy and Performance Optimization

We fine‑tune sequencing, reset strategies, and part‑load performance to match real‑world demand. Small corrections—proper subcooling/superheat, balanced flows, optimized condenser approach, and smart setpoints—deliver noticeable gains in kW/ton. We can integrate with your BMS or deploy stand‑alone controls to improve visibility and reliability while reducing total cost of ownership.

Safety, Quality, and Transparency

Your facility deserves work that’s safe, compliant, and traceable. Our technicians follow strict lockout/tagout procedures, maintain clean work areas, and document findings with photos and data. You’ll receive up‑front pricing, repair options, and clear timelines before work begins—no surprises, just dependable results backed by workmanship warranties.
