Fontana Commercial Chiller Maintenance

What We Service and Optimize

Our commercial chiller maintenance in Fontana covers diverse applications—office campuses, healthcare, logistics hubs, education, retail centers, manufacturing, and mixed‑use facilities. We maintain and optimize air‑cooled and water‑cooled plants, chilled‑water loops, pumps, towers, heat exchangers, and controls for steady capacity and lower lifecycle cost.

• Air‑cooled and water‑cooled chillers
• Centrifugal, screw, and scroll machines
• Magnetic‑bearing and VFD‑driven systems
• Cooling towers, condenser water, and chilled‑water loops
• Plate‑and‑frame heat exchangers and glycol systems
• Controls, sensors, safeties, and BMS/BAS integrations

Preventive Maintenance—Engineer Designed

Our PM programs are built to ASHRAE‑informed best practices and tailored to your load profile, runtime hours, and local climate. The result: stable capacity, fewer emergency calls, and measurable energy savings.

• Full operational logs, vibration and bearing checks
• Refrigerant charge verification, leak testing, and subcool/superheat analysis
• Oil and filter assessments; oil analysis with lab reports when required
• Condenser and evaporator tube cleaning; coil cleaning for air‑cooled units
• Cooling tower inspection, alignment, and water‑treatment coordination
• Electrical inspections, MCC checks, contactors, terminations, and VFD tuning
• Sensor calibration, control loop review, alarms and safety device verification
• Pump alignment, valve and strainer inspections, insulation integrity

Each visit ends with a clear report: findings, photos, trends, and prioritized recommendations—so you can plan budgets and avoid surprises.
