Commercial Centrifugal Chiller Service in Ontario, CA

Commercial Centrifugal Chiller Services We Offer

We deliver end‑to‑end support for centrifugal chillers in Ontario, CA — from design through operations. Our engineers handle the hard parts so you get reliable capacity, efficient part‑load performance, and predictable operating costs.

• Design, installation, and startup/commissioning for new centrifugal chillers and chiller plants
• Emergency repair and same‑day diagnostics for trips, surging, vibration, and capacity loss
• Preventive maintenance programs tailored to load profile, process criticality, and OEM guidelines
• Controls modernization: PLC/BCS integration, sensors, sequencing, trending, and alarming
• VFD retrofits and optimization for condenser and chilled‑water pumps, cooling tower fans, and compressors where applicable
• Tubesheet and bundle service: tube cleaning, eddy current testing, and leak remediation
• Oil analysis, bearing inspection, alignment checks, and vibration analysis
• Refrigerant management: leak detection, recovery, charge optimization, and documentation
• Water‑side services in coordination with water treatment partners for stable tower and condenser performance
• Retrocommissioning and energy tuning to meet Title 24 objectives and utility incentive criteria

Deep Technical Capabilities

Whether your plant uses single‑stage or two‑stage centrifugal machines, conventional or magnetic bearing designs, our team brings disciplined engineering to every service call. We address root causes — hydraulics, controls logic, heat‑exchange fouling, refrigerant charge, oil system health, and tower performance — so fixes last and KPIs improve.

• Load profiling and sequencing strategies to prevent surge at light loads
• Setpoint optimization (evaporator, condenser, and differential) for stable operation
• Pump and tower integration to support condenser approach and minimize lift
• Trend‑driven maintenance using vibration, temperature, pressure, flow, and power data
• Refrigerant transitions planning (e.g., lower‑GWP options where applicable) with risk, cost, and performance analysis

Our engineers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That foundation in advanced HVAC manufacturing principles informs our QA, safety, and commissioning standards on large‑tonnage equipment.

Energy, Compliance, and Documentation

We build energy and compliance into every scope. Expect measurement‑based proposals, clear commissioning plans, and records your facilities team can trust.

• Title 24‑minded control strategies, sequences of operation, and trending
• Utility incentive support (where available) with pre‑ and post‑measure verification
• Refrigerant management logs, leak checks, and recovery documentation to support state rules
• Lockout/Tagout, JHA, and site‑specific safety plans for every mobilization

Result: lower kW/ton, fewer alarms, cleaner audits, and healthier indoor air for occupants — aligned with our core mission of healthy air for a healthy life.

FAQs

• How often should a centrifugal chiller be serviced?
  We recommend quarterly inspections with annual deep maintenance (tube cleaning, oil analysis, eddy current on a schedule), adjusted to your runtime and criticality.
• Can you help reduce energy costs?
  Yes — from setpoint and sequence tuning to VFD retrofits and water‑side optimization, we target lower kW/ton and help document savings for available incentives.
• Do you support controls integration?
  We integrate chiller controls with your BAS, add trending and alarming, and provide operator training and documentation for lasting results.
