Commercial Centrifugal Chiller Maintenance in Oxnard

Why Oxnard businesses choose #1 AC Guys

We are #1 AC Guys—Southern California’s fourth‑generation, family‑owned HVAC engineering company. With 80+ years of engineering expertise, we specialize in large and complex commercial systems where precise centrifugal chiller maintenance determines uptime, budget, and indoor air quality. Our mission is healthy air for healthier lives at work. We are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), and we apply disciplined, manufacturer‑grade procedures to every chiller we maintain.

From Oxnard’s coastal environments to inland heat, our programs address corrosion, water quality, load swings, and energy code expectations across Ventura County and neighboring regions.

What our centrifugal chiller maintenance includes

• Performance benchmarking: approach temperatures, kW/ton, load profiles, and trends
• Oil management: level/quality checks, oil analysis, acid/moisture testing, and scheduled changes
• Refrigerant care: charge verification, superheat/subcool checks, leak detection, and recovery if required
• Heat‑exchange health: condenser/evaporator tube inspections and cleaning, water‑treatment coordination
• Vibration and rotating assembly: vibration trend analysis, bearings inspection, alignment, and balancing
• Electrical and drives: starters, contactors, VFDs, megger tests, and motor protection review
• Controls and safety: sensor calibration, setpoint optimization, safeties verification, alarm logic review
• Purge and sealing: purge unit checks, gasket/seal inspections, relief device condition
• System integration: chilled/condenser water flow validation, valve operation, and tower interface checks
• Documentation: photos, readings, recommendations, and a prioritized action plan

These tasks reduce energy waste, extend asset life, and prevent nuisance trips—protecting production schedules and occupant comfort.

Support for AC PRO equipment and parts

We service AC PRO equipment and support facilities that rely on AC PRO for OEM‑grade parts, accessories, and controls. Our engineers align maintenance with manufacturer best practices and site requirements so your chiller plant performs consistently through peak seasons.

Benefits you can measure

• Lower kW/ton and utility spend
• Fewer unplanned outages and emergency calls
• Stable supply air temperatures and humidity control
• Cleaner heat‑exchange surfaces and improved capacity
• Clear compliance documentation and audit‑ready reports

Healthy indoor air starts with a well‑maintained central plant. Our preventive approach supports cleaner coils, tighter control, and steadier ventilation rates—vital for employee wellness and productivity.

Industries we serve

• Commercial offices and campuses
• Healthcare, labs, and life sciences
• Manufacturing and food processing
• Hospitality and entertainment venues
• Education and municipal buildings
• Data centers and tech facilities
• Retail and mixed‑use properties

Our proven process

1) Discovery and assessment: we gather system drawings, service history, and BMS data; document baseline performance; and identify quick wins.
2) Plan and schedule: we create a site‑specific PM scope, align with your production calendar, and coordinate chilled/condenser water and tower service windows.
3) Execute and verify: we perform maintenance, calibrate controls, and verify load‑based performance.
4) Report and optimize: you receive a digital report with photos, readings, and prioritized recommendations, including CAPEX/ROI paths for upgrades.

Warning signs your centrifugal chiller needs service

• Rising approach temperatures or declining tonnage
• Frequent short‑cycling or nuisance trips
• Unusual vibration or bearing noise
• Energy use trending up (higher kW/ton)
• Oil discoloration, high moisture, or acid alerts
• Refrigerant leaks or repeated top‑offs

If you notice any of the above, we can quickly diagnose root causes and stabilize operation before failures escalate.

Flexible plans for Oxnard and beyond

We offer seasonal start‑ups, quarterly or semiannual PM, and predictive programs tailored to your chiller’s age, loading, and water chemistry. After‑hours and off‑season work helps avoid downtime during peak occupancy.
