Commercial Centrifugal Chiller Maintenance in Rialto, CA

What Our Centrifugal Chiller Maintenance Includes

Our commercial programs are tailored to your load profile, run hours, and criticality. Each plan blends preventive, predictive, and performance optimization steps to protect your asset and budget.

• Oil and refrigerant management: oil analysis (acid, moisture, metals), oil replacement and filter changes, refrigerant sampling and leak detection, charge optimization.
• Mechanical integrity: vibration analysis, alignment checks, bearing inspection and lubrication, seal and purge system checks for low‑pressure applications.
• Heat-transfer restoration: condenser and evaporator tube cleaning, scale removal, tube sheet inspection, approach temperature verification.
• Electrical and motor health: megger/insulation resistance testing, contactor and starter inspection, MCC thermography, soft‑start verification.
• Controls and safety: sensor calibration, setpoint optimization, trending and alarms, safety interlock verification, sequence testing with BAS.
• Performance benchmarking: kW/ton tracking, load testing, approach and lift optimization, capacity verification and reporting.

Every visit concludes with a clear report: what we found, what we fixed, and what’s next to maximize reliability and efficiency.

Common Signs Your Chiller Needs Attention

• Rising kW/ton and energy bills.
• Frequent nuisance trips or surge events.
• Temperature control drift or humidity complaints.
• High approach temperatures indicating fouling.
• Oil contamination flags or refrigerant losses.

If you’re seeing any of these in Rialto or nearby Western Riverside communities, we can diagnose and stabilize performance quickly.

Planned Maintenance That Pays Back

Well‑executed PM reduces lifecycle cost, often paying for itself through lower energy use and fewer breakdowns. We document measurable improvements—like improved approach temperatures and reduced lift—and translate them into annualized savings so you can show value to stakeholders.

Rapid Response, Minimal Downtime

We prioritize commercial operations where cooling is business‑critical. Our teams are equipped for on‑the‑spot cleaning, adjustments, and component replacement whenever possible. When more extensive work is needed, we stage parts and schedule during low‑impact windows.

Safety and Environmental Stewardship

We follow strict lockout/tagout procedures, refrigerant handling best practices, and documented leak detection protocols. Our methods help protect your people, your equipment, and the environment while maintaining compliance.
