Commercial DDC (Direct Digital Controls) in Oxnard

What we deliver in Oxnard

#1 AC Guys provides end‑to‑end Commercial DDC (Direct Digital Controls) for Oxnard facilities—covering design, integration, programming, commissioning, and lifecycle service. We focus on performance, occupant health, and operational continuity while making your building easier to operate.

• DDC design and engineering for new construction and retrofits
• AC PRO‑compatible integration for packaged units, RTUs, VAV, VRF, heat pumps, and ventilation
• Programming, graphics, alarming, trends, and secure remote access
• Commissioning, retro‑commissioning, and performance tuning
• Open protocols: BACnet, Modbus, LonWorks
• Indoor air quality strategies: ventilation control, filtration, and monitoring
• Energy optimization, schedules, demand response, and analytics
• Service, preventive maintenance, and operator training

Our mission is healthy air for healthy lives. In commercial spaces, that means precise control of ventilation, pressurization, humidity, and filtration—implemented with robust DDC logic and verified by data.

Why #1 AC Guys for DDC

• 80+ years of engineering depth and a 4th‑generation family of engineers
• Factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)
• Proven on large, complex commercial projects with strict uptime requirements
• Strong focus on indoor air quality and code compliance
• Local Oxnard support with fast dispatch across Ventura County
• Clear documentation, operator training, and lifecycle partnership

From concept to turnover, you get an engineering‑driven process: needs analysis, basis‑of‑design, sequence of operations, point lists, network architecture, controller programming, graphics standards, and FAT/SAT commissioning.

AC PRO‑compatible expertise

We integrate and service AC PRO‑compatible HVAC equipment and controls architectures common across Southern California. Whether your facility relies on AC PRO‑supplied RTUs, fan coils, VAVs, or VRF from leading manufacturers, we design interoperable DDC solutions that speak open protocols and centralize control into your BAS.

Our engineers emphasize maintainability: intuitive graphics, logical naming, alarm strategies that reduce noise, and trend logs that make diagnostics fast. The result is a system your team can trust—day one and five years later.

Industries we serve

• Office and mixed‑use buildings
• Manufacturing and light industrial
• Cold storage and food processing
• Healthcare clinics and labs
• Retail and hospitality
• Education and public facilities

Every market faces unique ventilation and control challenges. We tailor sequences for occupancy patterns, fresh air, filtration levels, humidity targets, and energy goals—validated by commissioning and live performance data.

Healthy air, measurable performance

We design DDC to actively protect indoor air quality: demand‑controlled ventilation, economizer optimization, filtration monitoring, and zone‑level control. Trend data lets you verify air changes, temperature, and humidity in real time, while alarms highlight exceptions before they become downtime.

Security and interoperability

We implement segmented networks, role‑based access, secure remote connections, and standardized naming. Using BACnet, Modbus, and LonWorks, we integrate legacy and new equipment into a unified BAS without locking you into proprietary traps.

Our process

• Assess: site survey, data review, and goals alignment
• Design: sequences, network design, point lists, submittals
• Build: panel fabrication, installation oversight, safe controls wiring
• Program: controller logic, graphics, alarms, trends
• Commission: point‑to‑point, functional testing, operator training
• Support: monitoring, maintenance, and performance tuning

This disciplined approach minimizes change orders, speeds turnover, and ensures the DDC system performs as intended.

Service area

We proudly serve Oxnard and all of Ventura County, with expanded coverage across Los Angeles County, Orange County, and Western Riverside County. If your portfolio spans multiple sites, we standardize controls and graphics for consistency.

Frequently asked questions

Q: Can you integrate our existing AC PRO‑supplied rooftop units into a new BAS?
A: Yes. We design AC PRO‑compatible integrations using open protocols to centralize control, trending, and alarms.

Q: Do you support mixed manufacturers and legacy equipment?
A: Absolutely. We routinely bridge BACnet, Modbus, and LonWorks to unify old and new gear under one interface.

Q: How do you ensure healthy indoor air?
A: With sequences for ventilation, filtration, economizers, humidity control, and real‑time monitoring that verifies performance.

Q: Are your engineers factory‑trained?
A: Yes—at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China).
