Commercial Centrifugal Chiller Maintenance in Fontana for AC PRO Systems

When your building depends on centrifugal chillers, maintenance quality shows up in every metric—energy intensity, reliability, acoustics, and indoor air quality. #1 AC Guys designs service programs around your AC PRO chiller plant’s real operating conditions, from part‑load cruise to peak summer demand, so you get predictable performance without surprises.

What our commercial maintenance includes

• Compressor health: vibration analysis and trending, bearing inspections, alignment, and VFD checks
• Heat‑transfer restoration: condenser/evaporator tube cleaning, scale removal, eddy‑current testing, and approach temperature optimization
• Oil and refrigerant care: oil sampling, acid/moisture checks, filter changes, refrigerant leak detection, recovery, and charge verification
• Controls and BAS: setpoint tuning, sensor calibration, network health, and optimization for demand response and staging
• Safety and compliance: safeties validation, purge system checks, documentation in line with EPA Section 608 and local codes
• Plant efficiency: sequencing, chilled‑water reset, condenser water strategies, and kW/ton improvement plans

Each visit produces a clear report with findings, trend data, and prioritized actions—so you can plan budgets and avoid emergency downtime.

We maintain AC PRO‑equipped plants across Fontana and the surrounding Inland Empire within our extended service area, while our home base covers Los Angeles County and nearby regions including Orange County, Ventura County, and Western Riverside County.

Our process

1) Assessment and baselining: We document nameplate data, recent work orders, alarms, and current kW/ton. We align on performance goals and critical loads.
2) Precision PM plan: Tasks are scheduled by runtime, water quality, and seasonal needs. We define KPIs and reporting cadence.
3) Execution and optimization: Maintenance, repairs, and controls tuning are performed with minimal disruption, often during low‑load windows.
4) Continuous improvement: We review trends quarterly, recommending operational or minor retrofit changes that cut energy and wear.

Energy and reliability gains you can measure

• Lower energy use via better approach temps, stable lift, and optimal staging
• Fewer nuisance trips through predictive diagnostics and vibration trending
• Longer asset life by maintaining lubrication quality and clean heat‑exchange surfaces
• Cleaner indoor air with proper coil hygiene, water‑side care, and controls calibration

Whether you operate a single AC PRO centrifugal chiller or a multi‑chiller plant, we tailor your plan to runtime and risk—so you only pay for work that moves the needle.

Documentation and compliance

Our reports support audits and capital planning. We follow ASHRAE best practices, Title 24 considerations, and EPA Section 608 requirements for refrigerant handling. You’ll have organized service records to protect assets and assist with regulatory needs.

Complementary services

• Water treatment coordination to protect tubes and towers
• BAS integration and sequence refinement
• Retro‑commissioning and chiller plant optimization
• Seasonal start‑up/shutdown and emergency response

We understand plants must run—production, tenants, and patients depend on it. That’s why our engineers schedule around your operations and communicate clearly, from pre‑job hazards to post‑job performance.
