Commercial Centrifugal Chiller Service in Fullerton

From the first site walk to commissioning, our engineer‑led process ensures your centrifugal chiller is evaluated as part of a complete plant—pumps, towers, heat exchangers, controls, and distribution. We work seamlessly with AC PRO–supplied equipment and parts, integrating upgrades that improve reliability and reduce total cost of ownership.

What we service and optimize

• Centrifugal chiller diagnostics: vibration trends, oil analysis, infrared scanning, and control point verification
• Tube bundle care: brush and chemical cleaning, eddy‑current testing, leak detection, and gasket replacement
• Refrigerant management: charge verification, pressure‑temperature cross‑checks, moisture and acid testing
• Drives and starters: VFD tuning, soft‑start verification, harmonics checks, motor insulation testing
• Controls and BMS: sequence of operations review, sensor calibration, chilled water reset, condenser water optimization
• Energy upgrades: VFD retrofits, tower fan optimization, high‑efficiency tube inserts, advanced control strategies
• Commissioning and re‑commissioning: baseline creation, kW/ton validation, trending, and training

Why facilities in Fullerton choose #1 AC Guys

We are a fourth‑generation family business with 80+ years in engineering. Our team is factory‑educated by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), and we apply that rigor to every chiller plant we touch. Our focus is large and complex commercial projects where precision matters—hospitals, life‑science labs, higher‑education campuses, data centers, government buildings, and high‑rise offices.

We support AC PRO centrifugal chiller systems and AC PRO–sourced components, providing service plans, repairs, and modernizations that align with your budget and operating profile. Whether your goal is reliability, capacity recovery, or energy reduction, we deliver measurable improvements with clear before‑and‑after data.

Our maintenance methodology

• Plan: Establish plant goals, sequences, and seasonal strategies tied to occupancy and load profile
• Measure: Log trends for temperatures, pressures, flows, and power to identify hidden inefficiencies
• Act: Calibrate sensors, clean tubes, optimize condenser water, and tune control loops and VFDs
• Validate: Confirm capacity and kW/ton against baseline; document results with a simple, visual report

Result: lower energy use, fewer nuisance trips, stabilized leaving water temperatures, and extended equipment life.

Common problems we solve

• High kW/ton and poor IPLV caused by fouled tubes or non‑optimized condenser water
• Inlet guide vane and VFD control conflicts leading to surge or hunting
• Nuisance low‑oil or high‑head trips traced to sensor drift or sequence gaps
• Capacity shortfall under peak load due to flow imbalance or air in system

Each issue is addressed with root‑cause diagnostics—not guesswork—so fixes last.

Health, safety, and indoor air quality

Our mission is healthy air for a healthy life. For commercial plants, that means reliable chilled water for stable indoor temperature and humidity, proper ventilation rates, and filtration that supports occupant well‑being. We align service with safety and environmental stewardship, including careful refrigerant handling and documentation.

Project delivery and transparency

Expect clear scopes, firm pricing, and communication tailored to facility teams. You’ll receive trend charts, photos, and a concise action plan after each visit. When retrofits make financial sense, we model energy impact and life‑cycle cost to support your capital planning.

24/7 coverage and service area

We dispatch rapidly to Fullerton and throughout Orange County, with extended coverage across Los Angeles County, Ventura County, and Western Riverside County. Whether you need emergency service, seasonal commissioning, or a long‑term maintenance program, our team is ready.
