Commercial Centrifugal Chiller Maintenance in Fullerton, CA

#1 AC Guys delivers comprehensive commercial centrifugal chiller maintenance in Fullerton designed to maximize uptime, efficiency, and indoor air quality. As a fourth‑generation family of engineers with 80+ years in engineering, we bring a disciplined, data‑driven approach to complex mechanical systems so your building stays comfortable, compliant, and cost‑efficient.

What our centrifugal chiller maintenance includes

• Seasonal inspections, start‑up/shut‑down procedures, and operational baselining
• Tube cleaning, brushing, and chemical descaling to restore heat transfer
• Eddy current testing to identify pitting, fouling, and thinning in tube bundles
• Oil analysis (acidity, moisture, metals) and oil/refrigerant compatibility checks
• Refrigerant analysis, leak detection, recovery/charge verification, and EPA 608 compliance documentation
• Purge unit inspection (where applicable), seals, and relief device checks
• Vibration analysis and alignment verification for motor/drive/impeller components
• Electrical testing: contactors, terminations, megger tests, and overload settings
• Controls calibration: sensors, actuators, setpoints, safeties, and trending
• VFD review and optimization for part‑load efficiency
• Cooling tower coordination: basin condition, nozzles, fill, fans, and seasonal layup
• Water treatment coordination to control scale, corrosion, and biological growth
• Air and water balancing assistance to confirm design flow and stable operation
• Detailed service reports with performance metrics, photos, and recommendations

Our preventive plans are tailored to your load profile and process risk, helping you avoid unplanned outages while capturing measurable energy savings.

Outcomes you can measure

• Lower kW/ton through restored heat transfer and optimized controls
• Fewer emergency calls and extended equipment life cycle
• Stable supply temperatures that protect production, comfort, and IAQ
• Clear documentation for audits, sustainability reporting, and budgeting
• Improved occupant health by supporting cleaner, properly dehumidified air

Why facilities in Fullerton choose #1 AC Guys

• Fourth‑generation family business with 80+ years in engineering
• Factory‑educated at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)
• Expertise in large, complex commercial and industrial projects
• 24/7 rapid response for mission‑critical environments
• Safety‑first culture, from lockout/tagout to environmental stewardship
• Transparent reports and proactive capital planning guidance

We specialize in solving tough problems—intermittent trips, efficiency drift, persistent alarms, and chronic fouling—by combining precise diagnostics with practical, budget‑smart remedies.

Energy and reliability optimization

Beyond routine maintenance, our engineers tune systems for real‑world operating conditions. We calibrate sensors and safeties, optimize VFD sequences for part‑load, align chiller, pump, and tower setpoints, and coordinate water treatment to preserve tube integrity. When needed, we recommend targeted upgrades that deliver strong ROI—such as improved filtration, better BAS trend logic, or tower fan/VFD adjustments—to reduce kW/ton without compromising capacity.

Compliance, safety, and documentation

Our work aligns with industry standards and local code requirements. We provide EPA 608‑compliant refrigerant handling, maintain MSDS and service logs, and deliver digital reports that support Title 24 performance objectives, utility incentives, and sustainability targets. You get traceable records that simplify audits and stakeholder reporting.
