Commercial Centrifugal Chiller Service in Glendale

As Glendale’s engineer‑driven HVAC partner, #1 AC Guys delivers commercial centrifugal chiller services that unite deep technical rigor with practical jobsite execution. Our mission is healthy, efficient air for healthier lives—and for mission‑critical facilities, that starts with a stable, optimized chiller plant.

What we do for centrifugal chillers

• Installation and replacement of centrifugal chillers, pumps, and cooling towers
• Emergency and scheduled repairs, from sensor faults to impeller and seal issues
• Performance optimization: setpoints, VFD tuning, variable primary flow, and sequencing
• Preventive maintenance: tube cleaning, eddy current testing, oil and refrigerant analysis
• Controls integration: BAS, BACnet/Modbus, alarms, trending, and analytics
• Retro‑commissioning and Title 24 compliance documentation
• Water treatment coordination and condenser performance recovery

Every decision we make is backed by measurements—approach temperatures, lift, kW/ton, flow balance, and vibration trends—so you see exactly how your plant is performing and where the savings are.

Deep engineering for better outcomes

With 80+ years of engineering experience across four generations, our team treats your chiller as an integrated system. We evaluate load profiles, pump curves, tower capacity, control sequences, and occupant comfort to eliminate the root causes of instability and excess energy use. Our formal factory training includes Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We apply those disciplined methods across most major chiller platforms used in commercial buildings.

Installation and replacement

Whether you are upgrading for capacity, efficiency, or refrigerant strategy, we handle end‑to‑end delivery—engineering review, rigging plans, piping, electrical, controls, commissioning, and closeout. We align designs with Glendale code requirements and California Title 24. Where applicable, we help you explore potential rebates or incentives through Glendale Water & Power or regional programs.

• Right‑sizing via load analysis to reduce cycling and improve part‑load efficiency
• Primary/secondary or variable primary flow strategies tailored to your plant
• Smart sequencing to stage chillers and towers for the lowest kWh/ton
• Refrigerant planning, including low‑GWP options where suitable

Repairs done right

From intermittent trips to chronic NPLV underperformance, we resolve complex faults with engineer‑grade diagnostics. We verify sensors, check differential pressures, confirm flow, assess condenser approach, and review control logic to isolate the issue before we replace a single part. When you call us, expect a clear test report and a plan that shows cost, risk, and ROI.

Preventive maintenance program

• Tube cleaning and eddy current testing to restore heat‑transfer surface
• Oil analysis for moisture, acids, metals, and dielectric strength
• Vibration trending to catch bearing and alignment problems early
• Controls review: safeties, alarms, trend intervals, and sequence integrity
• Seasonal tower service: basin cleaning, nozzle checks, fan and gearbox inspection

Result: more uptime, better efficiency, and fewer emergency calls.

Controls and integration

We integrate chillers, pumps, and towers into your building automation system with clean point lists and well‑documented sequences. BACnet and Modbus communications, alarming, and trending create visibility for your operators and accountability for results.

Water‑side excellence

Chiller performance lives and dies on the water side. We coordinate with your water treatment provider to manage scale, corrosion, and biological growth. Balanced flows, proper condenser entering water temperatures, and optimized tower setpoints bring head pressure down and efficiency up.

Compliance and documentation

Expect clean submittals, commissioning checklists, startup forms, and Title 24 documentation. We deliver closeout packages that make maintenance straightforward for years to come.

Industries we serve in Glendale

• Office and mixed‑use buildings
• Healthcare and medical offices
• Hospitality and entertainment
• Education and public facilities
• Retail centers and warehouses

We understand that every hour of downtime has a cost. Our Glendale crews respond quickly, communicate clearly, and leave your plant safer and more efficient than we found it.

Transparent reporting and ROI

After each service, you receive data‑driven findings: approach temperatures, kW/ton snapshots, vibration and oil results, and specific recommendations prioritized by ROI. This makes budgeting easier and helps justify upgrades with facts—not guesswork.

Service area

Based in Los Angeles and proudly serving Glendale, we cover Los Angeles County and nearby areas including Orange County, Ventura County, and Western Riverside County. One team, one standard—engineer‑level quality on every call.
