Commercial Centrifugal Chiller Maintenance in Pasadena

Comprehensive Centrifugal Chiller Maintenance—Built for Pasadena’s Commercial Loads

We keep your centrifugal chillers reliable, efficient, and compliant with a maintenance program tailored to your building’s load profile and water quality. Our 4th‑generation family of engineers brings 80+ years in engineering to every service, blending precision diagnostics with practical solutions that respect your budget and timeline.

• Performance baselining: approach temperature, kW/ton, condenser/evaporator pressures, and trending
• Controls calibration: safeties, setpoints, staging, and sensor verification
• Mechanical integrity: bearings, seals, alignment checks, couplings, and vibration diagnostics
• Heat‑exchange optimization: condenser/evaporator tube cleaning, scale/organic fouling mitigation, and water‑treatment guidance
• Refrigerant stewardship: leak checks, charge optimization, superheat/subcool assessment, and documentation
• Electrical inspections: starters/VFDs, contactors, megger testing, and protective devices
• Oil and chemistry: oil analysis, filter changes, acid tests, and moisture control
• Safety and compliance: relief valves visual checks, ventilation, housekeeping, and lockout/tagout best practices

Our goal is simple: maximum uptime, minimum energy waste, and healthier indoor air for your occupants.

AC PRO Compatibility and Multi‑Brand Central Plants

We routinely maintain systems sourced through AC PRO and mixed‑OEM central plants, integrating parts and controls to keep your chiller room reliable. Whether your equipment is paired with AC PRO‑stocked components or other OEM assemblies, we verify interoperability, document model/serial data, and maintain a clear service history for smarter capital planning.

Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). This foundation supports our work on large and complex projects while aligning with manufacturer best practices.

Our Process

We start with a site survey and a data‑driven PM plan. You’ll receive a scope, schedule, and safety plan before work begins. After maintenance, we deliver a report with findings, photos, and performance metrics, plus recommendations prioritized by risk, efficiency impact, and lifecycle value.

Need help before peak temperatures? We offer accelerated scheduling for Pasadena properties and coordinate closely with building management to avoid disrupting tenants or critical operations.

What’s Included in a Typical PM Visit

• Operational checks, trending, and approach temperature verification
• Condenser/evaporator tube inspection and cleaning as needed
• Oil analysis and filtration; refrigerant leak detection and charge optimization
• Controls testing: safeties, sensors, actuators, and setpoint calibration
• Electrical system inspection: starters/VFDs, connections, and insulation testing
• Vibration checks and mechanical integrity review
• Cooling tower/condenser water coordination and water‑treatment recommendations
