Commercial Control Systems in Orange — York-Compatible Specialists

Choose a controls partner that treats your building like a mission‑critical system. #1 AC Guys is a 4th‑generation family of engineers with 80+ years in engineering, delivering York‑compatible commercial control systems across Orange and Orange County. We design, install, program, and commission robust solutions for YORK and mixed fleets using open standards that protect your investment and simplify future upgrades.

Engineering-first commercial controls

Every facility is unique. We start with a detailed survey, data logging, and sequence review to identify comfort gaps, ventilation issues, and energy waste. Then we engineer a control strategy that balances indoor air quality, thermal comfort, equipment longevity, and Title 24 compliance—without locking you to a single vendor.

• Design of Sequences of Operation for YORK RTUs, chillers, DOAS, VAV, and hydronic plants
• Retrofit controls for older units, including sensor packages, VFDs, economizers, and demand control ventilation
• BMS integration via BACnet/IP, BACnet MS/TP, and Modbus (RTU/TCP)
• Programming, graphics, trending, dashboards, remote monitoring, and alarming
• Functional performance testing and commissioning with complete documentation
• IAQ strategies: ventilation verification, CO2 monitoring, filtration upgrades, and control tuning
• Proactive maintenance and rapid-response service to protect uptime

York-compatible and multi-brand integration

Whether your site runs YORK exclusively or a mix of manufacturers, our controls are built on open protocols for clean interoperability. We integrate rooftop units, chillers, boilers, VAV boxes, and energy meters into a cohesive platform with intuitive graphics and granular control—so your team can manage setpoints, schedules, trends, and alarms from anywhere.

Our goal is straightforward: give you reliable, vendor‑agnostic control that reduces energy costs, extends equipment life, and maintains healthy indoor air—day after day, season after season.
