Commercial DDC (Direct Digital Controls) in Calabasas

When aging controls, hot/cold complaints, and rising utility bills collide, Direct Digital Controls (DDC) deliver the measurable stability modern buildings need. In Calabasas, #1 AC Guys engineers design and support commercial DDC and Building Automation Systems (BAS) that optimize comfort, protect indoor air quality, and streamline operations—without locking you into a single vendor.

What we deliver for Calabasas facilities

• Design/build DDC and BAS for new construction and retrofits
• Migration from pneumatics and proprietary EMS to open BACnet/Modbus
• Controller programming and engineered sequences of operation
• Integration of VRF, VAV, RTUs, chillers/boilers, pumps, and VFDs
• Indoor air quality sensors (CO2, PM2.5, VOC) and demand‑controlled ventilation
• Custom graphics, dashboards, alarm management, and trend logging
• Commissioning, retro‑commissioning, and ongoing optimization
• 24/7 remote monitoring, alerts, and priority service

Our team is factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That training, combined with 80+ years in engineering across four generations, helps us solve tough integration challenges and keep multi‑brand systems operating as one.

Engineering‑first process for predictable results

Every commercial DDC project follows a documented path for clarity and control:

• Site survey and data capture of existing equipment and controls
• Load, airflow, zoning, and sequence review to define the strategy
• Detailed submittals: I/O schedules, control diagrams, and points lists
• Controller programming, graphics, alarming, and trending
• Factory‑level startup and functional performance testing
• Owner training, operations manuals, and turnover package
• Monitoring‑based maintenance and seasonal re‑tuning

Open protocols, secure connectivity

We prioritize open, interoperable architectures—BACnet/IP, BACnet MS/TP, and Modbus TCP/RTU—so your building stays flexible and serviceable. We harden networks with role‑based access, secure remote connections, and clear IT coordination, balancing uptime with cybersecurity best practices.

Healthy indoor air—by design

Our mission is healthy air for healthy lives. In commercial spaces that means control strategies tuned to people and process:

• CO2‑based ventilation with adjustable setpoints for occupancy
• Optional PM2.5 and VOC sensing to validate IAQ improvements
• Temperature/humidity optimization to deter mold and discomfort
• Smart purge modes and flush cycles during off‑hours

These strategies support comfort, wellness, and compliance goals while minimizing energy penalties.

Industries we serve

• Office and multi‑tenant buildings
• Retail, restaurants, and entertainment
• Healthcare suites and wellness centers
• Schools, worship, and community facilities
• Hospitality and event spaces
• Light industrial, labs, and R&D
• Multifamily common areas and clubhouses

Systems we expertly control

• VRF/VRV systems, including heat recovery
• VAV with reheat, DOAS, and economizers
• Rooftop units, split systems, fan coils, and air handlers
• Chiller/boiler plants with primary/secondary pumping
• Exhaust and makeup air, pressurization, and relief

From single‑site upgrades to campus‑wide integrations, our controls unify these assets into one intuitive, maintainable platform.
