Commercial Centrifugal Chiller Repair in Los Angeles

What We Repair and Optimize

When a centrifugal chiller underperforms, your entire facility feels it—comfort, process cooling, and energy spend. #1 AC Guys brings deep engineering rigor to restore reliability and efficiency across Los Angeles and surrounding counties.

• Root‑cause diagnostics for surge, high approach temperatures, nuisance trips, and capacity loss
• Controls and VFD troubleshooting, tuning, and sequencing for stable setpoints
• Refrigerant leak detection, evacuation, dehydration, and compliant charging
• Tube cleaning (mechanical/chemical) and condenser/evaporator performance recovery
• Eddy current tube testing and integrity reporting
• Oil analysis, filtration, and contamination remediation
• Laser shaft alignment and vibration analysis to reduce wear
• Compressor inspections, bearings/seals replacement, purge unit service
• Chilled water/condensing water optimization and pump balancing
• Retrofits: controls upgrades, variable speed, low‑GWP refrigerant conversions where applicable

We work across central plants, district cooling loops, data centers, and mission‑critical environments where downtime is not an option.

Expert Diagnostics You Can Measure

Our engineers capture and interpret operating data so you can see exactly what’s happening and why. That means informed decisions and no guesswork.

• Live trending of temperatures, pressures, flows, kW/ton, and approach
• Vibration and sound signature analysis for bearings and rotating assemblies
• Oil quality tests (acidity, moisture, particulates) with documented results
• Eddy current mapping for tube health and proactive planning
• Control logic review, alarm history analysis, and sequence verification

Every service call concludes with a clear report: findings, photos, data, and prioritized actions—immediate fixes, near‑term optimizations, and strategic upgrades.

Reliable Repairs and Smart Retrofits

From urgent repairs to planned overhauls, we focus on durable solutions that extend asset life and reduce kW/ton. Our fourth‑generation engineering know‑how shines on complex projects and multi‑chiller plants.

• Mechanical repairs: seals, bearings, couplings, purge components
• Heat‑exchange recovery: tube cleaning, re‑gasketing, micro‑fouling mitigation
• Controls/VFD: sensor calibration, loop tuning, surge avoidance strategies
• Water‑side upgrades: setpoint resets, differential pressure control, valve commissioning
• Low‑GWP pathways: consultation on refrigerant options and phased conversions

All work is performed with safety front‑of‑mind and in compliance with EPA refrigerant regulations and applicable California codes.

Preventive and Predictive Maintenance Plans

The most cost‑effective chiller is a clean, well‑tuned chiller. Our maintenance programs are tailored to your plant, load profile, and budget.

• Seasonal start‑up/shutdown and annual performance benchmarking
• Condenser/evaporator tube maintenance schedule to prevent efficiency drift
• Oil and refrigerant health programs to catch issues early
• BAS/BMS integration checks and alarm strategy improvements
• VFD health checks, bearing inspection, and alignment verification

We align maintenance with your energy and sustainability goals, supporting compliance with Title 24 and local air quality requirements while enhancing occupant comfort and indoor air quality—because healthier air supports healthier lives.

Compliance, Safety, and Sustainability

We handle refrigerants responsibly, maintain accurate records, and follow safe work practices. Our recommendations consider performance, reliability, and environmental impact—helping you plan for lower‑GWP refrigerants and efficiency upgrades without compromising uptime.

For facilities pursuing sustainability targets, we provide measurable improvements in kW/ton, water‑side delta‑T, and load matching—documented so you can track ROI.
