Commercial Control Systems in Orange, CA

#1 AC Guys brings 80+ years of multi‑discipline engineering experience to commercial HVAC controls in Orange, California. We specialize in complex, multi-zone environments where comfort, air quality, and energy performance must work in sync. Our mission is healthy air for a healthy life—delivered through smart control strategies, precise commissioning, and continuous support.

What we deliver

• Engineer-led design for Commercial Control Systems across RTUs, heat pumps, VRF/VRV, DOAS, and ventilation
• AC PRO–compatible components integration with reliable parts availability in Southern California
• Controls installation, programming, and graphics tailored to facility teams
• BAS/BMS integration (BACnet, Modbus) with trend logs, alarms, and schedules
• Demand control ventilation, economizers, and zoning for measurable energy savings
• Indoor air quality sensors (CO2, VOC, PM2.5) and filtration management to support occupant health
• Retro-commissioning, upgrades, and conversions without disrupting operations
• Title 24-aligned sequences and documentation to streamline compliance

From concept through commissioning, we own the details—sequence of operations, sensor placement, airflow strategy, and verification—so your system performs on day one and every day after.

Why engineer-led matters

Complex buildings need more than generic controls; they need engineered solutions. Our fourth‑generation family of engineers has designed and tuned systems for decades. Our team has trained at manufacturer facilities including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That background helps us bridge equipment behavior with real‑world control logic, delivering stability, comfort, and efficiency you can measure.

AC PRO and system compatibility

We design control strategies that work seamlessly with AC PRO–compatible controllers, sensors, and accessories across packaged and split systems, heat pumps, VRF, and ventilation equipment. We also integrate with equipment from leading global manufacturers including Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier, unifying disparate systems under one practical, serviceable controls architecture.

Whether you operate an office, retail plaza, medical clinic, school, or light industrial space in Orange, our solutions prioritize uptime, air quality, and predictable costs—without locking you into a single vendor path.

Our process

• Assess: Site walk, equipment survey, and goals (comfort, IAQ, energy, compliance)
• Engineer: Load considerations, sensor mapping, sequence of operations, and network design
• Install & program: Controllers, I/O, sensors, damper actuators, and safe wiring practices
• Commission: Point-to-point checks, functional tests, and balancing support
• Verify: Trending, tuning, and acceptance documentation for facilities and compliance
• Train & handoff: Clear O&M guides, setpoint policies, and alarm response flow
• Maintain: Preventive service, firmware updates, and 24/7 emergency response

The result is a robust control system that your facilities team can operate confidently, with visibility into performance and the tools to prevent issues before they impact occupants.

Health-first control strategies

Healthy air is our mission. We leverage demand control ventilation and IAQ sensing (CO2, VOC, PM2.5) to maintain fresh air and filtration targets while balancing energy. We design sequences that coordinate outdoor air, economizers, and supply fan control to meet indoor air quality goals with minimal waste.

Better control means better outcomes: steadier temperatures, quieter operation, fewer hot/cold calls, and lower operating costs. It also supports productivity and tenant satisfaction—key metrics for any commercial portfolio.

Industries we serve in Orange

• Office and creative campuses
• Retail and mixed-use
• Healthcare clinics and dental
• Education and childcare
• Hospitality and restaurants
• Light industrial and warehouses
• Multi-tenant properties and associations

Every facility is different, so we tailor control logic to your actual loads, occupancy patterns, and ventilation needs—not just design-day assumptions.

Energy, compliance, and documentation

We align programming with California Title 24 control requirements and industry best practices such as ASHRAE guidance. You receive clear submittals, as-builts, points lists, and sequence documentation that make maintenance and future upgrades straightforward.

Need to justify upgrades? We provide baseline metrics and projected savings, plus post-install verification using trend data to demonstrate improvements in kWh, demand, and comfort stability.

Service area and response

We serve the City of Orange and all of Orange County with rapid dispatch. Our broader coverage includes Los Angeles County, Ventura County, and Western Riverside County. For operations that span multiple sites, we standardize controls and reporting so your team manages everything from a single pane of glass.

When urgency strikes, our 24/7 emergency support and stocked service vehicles help protect critical operations and occupant comfort.

Upgrades, retrofits, and expansions

Whether you are replacing aging rooftop units, adding zones, or migrating from legacy thermostats to BAS, we plan around your occupancy to minimize disruption. We keep existing assets working while phasing in new controls, then validate system performance with trending and staff training.
