Commercial Centrifugal Chiller Maintenance in Los Angeles

When Los Angeles businesses need reliable, cost‑smart centrifugal chiller maintenance, they turn to #1 AC Guys. We are a fourth‑generation family of engineers with 80+ years of engineering expertise, known for solving complex commercial HVAC challenges across LA County and neighboring Orange County, Ventura County, and Western Riverside County. Our mission is healthier indoor air and stable comfort, powered by chillers that run efficiently, safely, and predictably.

What our centrifugal chiller maintenance includes

• Performance benchmarking and load‑based testing to verify capacity, efficiency, and kW per ton.
• Oil and refrigerant analysis to detect moisture, acidity, wear metals, and contamination early.
• Condenser and evaporator tube inspection, brushing, and descaling to restore heat‑transfer efficiency.
• Vibration trending and bearing condition checks for proactive protection of rotating assemblies.
• Starter and VFD inspection, contactor assessment, megger testing coordination, and setpoint validation.
• Controls calibration: sensors, safeties, chilled and condenser water setpoints, and sequencing.
• Leak detection and EPA‑compliant refrigerant handling with accurate charging and documentation.
• Purge system service, seals and gaskets inspection, and purge run‑time evaluation.
• Chilled water and condenser water flow verification, delta‑T analysis, and valve operation checks.
• Cooling tower and water‑treatment coordination to protect tubes, prevent scaling, and reduce fouling.
• Electrical, insulation, and piping inspections to prevent nuisance trips and energy waste.
• Digital reporting with photos, trends, and prioritized recommendations for budget planning.

Our team is factory‑trained at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). We apply rigorous OEM‑informed procedures and ASHRAE best practices across the centrifugal chiller plants we maintain.
