#1 AC Guys is a Southern California, fourth‑generation family business with 80+ years of engineering expertise. Our mission is healthy indoor air for healthier lives—delivered through reliable, efficient, and intelligent building systems. Our engineers trained at manufacturer facilities of Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), giving us a deep grasp of controls, sequences, and integration across complex commercial environments. From single facilities to multi‑site portfolios in Oxnard, we design maintenance that stabilizes comfort, reduces risk, and turns your BAS into a measurable energy asset.

What our BAS maintenance includes

• End‑to‑end system health check: controllers, gateways, networks, and field devices
• BACnet/Modbus point verification, device discovery, and communication integrity
• Sensor calibration: temperature, humidity, CO₂, VOC, pressure, and airflow
• Sequence optimization: economizers, reset strategies, setpoint tuning, VFD/VAV logic
• Firmware and security updates to supported controllers and supervisory platforms
• Alarm rationalization: prioritization, deadband tuning, and nuisance reduction
• Trend setup and analytics for energy, comfort, and IAQ performance
• Mechanical coordination: RTUs, VRF, chillers, boilers, heat pumps, and ventilation
• Panel cleaning, terminal tightening, and cable management to prevent faults
• Load profiling and scheduling for demand management and Title 24 compliance
• Documentation: as‑found/as‑left logs, recommendations, and lifecycle planning
