Pasadena Commercial Centrifugal Chiller Service — AC PRO Equipment

What we service and support

We focus on AC PRO centrifugal chillers used in demanding Pasadena commercial environments—central plants, high‑rise offices, healthcare, life sciences, education, hospitality, and industrial facilities. From single machines to multi‑chiller plants with primary–secondary or variable primary flow, we engineer reliability and efficiency at every step.

• Emergency diagnostics and repair for AC PRO centrifugal chillers
• Predictive and preventive maintenance (vibration, oil, and refrigerant analysis)
• Tubes and bundle service (eddy current testing, cleaning, descaling)
• Controls and BMS integration (BACnet/Modbus), setpoint optimization
• VFD retrofits and staging logic for energy savings
• Refrigerant management and leak mitigation aligned with California regulations
• Performance testing, commissioning, and re‑commissioning
• Retrofits, right‑sized replacements, and turnkey change‑outs

Expert care for AC PRO centrifugal chillers

Our team services AC PRO centrifugal chillers with a methodical, data‑centric workflow. We benchmark current performance (lift, approach temperatures, kW/ton), evaluate water‑side and air‑side conditions, review controls logic, and correct inefficiencies that drive energy waste or premature wear. The result: fewer nuisance trips, longer component life, and year‑round reliability for Pasadena facilities.

Maintenance that prevents downtime

A tailored maintenance plan protects your investment and stabilizes uptime. We structure service around your load profile and compliance needs.

• Vibration trending for bearings and rotating assemblies
• Oil and refrigerant analysis to protect compressors
• Tubesheet inspection, eddy current testing, and tube cleaning
• Condenser/evaporator approach tracking and fouling control
• Controls calibration, sensor validation, and alarm rationalization
• Cooling tower checks, water treatment coordination, and flow verification

Retrofits, energy upgrades, and Title 24 alignment

We design retrofit packages—VFDs, high‑efficiency motors, advanced controls, and optimized sequences—to lower kW/ton while maintaining capacity. Our engineers align upgrades with California Title 24 requirements and can assist with utility incentives, measurement and verification, and re‑commissioning to lock in savings.

Our engineered process

• Assess: Site survey, data logging, and performance baselines
• Engineer: Root‑cause analysis and right‑sized scopes of work
• Execute: Seasoned techs, factory‑informed procedures, safe work practices
• Support: Clear reporting, operator training, and ongoing optimization

Healthier air, reliable comfort

Healthy air starts with stable, efficient central plant operation. By controlling temperature, humidity, and filtration strategies across your system, we help protect occupants and processes while cutting energy use—fulfilling our mission of healthy air for a healthy life.

Fast response across Pasadena and beyond
