Commercial VRF/VRV System Repair in Los Angeles

At #1 AC Guys, every repair begins with engineering-first thinking. As a fourth‑generation family of engineers with 80+ years of cumulative engineering experience, we specialize in complex, multi-zone commercial VRF/VRV systems where precision, uptime, and healthy indoor air matter most. Our mission is simple: deliver healthier air and reliable comfort for healthy lives—at work as well as at home—through disciplined diagnostics, quality repairs, and optimized performance.

Serving Los Angeles County and nearby Orange County, Ventura County, and Western Riverside County, our team handles challenging sites across offices, retail, hospitality, education, and healthcare. We are factory-trained at the manufacturers’ plants of Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), bringing deep product insight to every call without the guesswork.

What we repair on VRF/VRV systems

• Inverter-driven compressors and outdoor condenser modules
• Branch/selector boxes and heat recovery distribution
• Electronic expansion valves (EEVs/LEVs) and oil return issues
• Thermistors, pressure sensors, and pipe temperature sensors
• Communication networks (indoor-outdoor comms, addressing, polarity)
• Central controllers, gateways, and BMS integrations
• Fan coils: cassettes, ducted, wall and floor consoles
• Refrigerant piping, leak detection, charge optimization, contamination cleanup
• Power quality problems, boards, and inverter module faults

Our diagnostic process

We combine factory procedures with field-proven testing to isolate true root causes and prevent repeat failures. Expect clear communication, documented findings, and repairs that hold up under heavy commercial use.

• Intake and history: symptoms, error codes, recent work, and operating profile
• System mapping: verify piping diagrams, addressing, zoning, and refrigerant routes
• Live data capture: pressures, temperatures, superheat/subcool, target vs. actual
• Advanced testing: electronic leak detection, nitrogen pressure decay, ultrasonic checks, thermal imaging, airflow profiling, and electrical analysis
• Root-cause analysis: component vs. control vs. design issues, not just the alarm
• Repair plan and quote: options prioritized by uptime, energy, and budget
• Execution and commissioning: precise charging, vacuum, calibration, controls tuning
• Performance verification: trend logs, delta-T, capacity recovery, and documentation
