Commercial Building Management System (BMS) Services in Orange, CA

When your Orange, CA facility needs a Commercial Building Management System that just works, #1 AC Guys brings engineering‑first execution. We unify HVAC equipment, ventilation, and controls into a dependable BMS that improves indoor air quality, lowers operating costs, and gives facility teams clear visibility with actionable data.

Engineered BMS solutions for complex commercial sites

Our team designs, installs, integrates, and services BMS across offices, retail, hospitality, education, healthcare clinics, light industrial, and mixed‑use properties. We’re fluent in BACnet/IP, BACnet MS/TP, and Modbus, and we build sequences that are transparent, maintainable, and compliant with California Title 24 and ASHRAE guidelines.

• Design‑build and retrofit BMS for new and existing buildings
• Integration of RTUs, VAVs, VRF/mini‑split, heat pumps, boilers, chillers, and ventilation systems
• Programming, graphics, trending, alarming, and dashboards for operators
• Fault detection and diagnostics (FDD) to prevent downtime
• Energy optimization, scheduling, and demand limiting
• IAQ monitoring with CO2, PM2.5, and VOC sensors
• Remote access, secure connectivity, and role‑based permissions
• Commissioning and retro‑commissioning for verified performance

AC PRO–compatible equipment and support

We service and install solutions compatible with AC PRO–supplied HVAC equipment common throughout Southern California. Whether you’re updating controls on existing assets or planning a full retrofit, we align the BMS with your mechanical systems to maximize efficiency and reliability—without locking you into proprietary platforms.

From parts sourcing to lifecycle planning, our goal is to make your AC PRO–compatible system easier to manage and more cost‑effective over time.

Factory‑trained specialists you can trust

#1 AC Guys is a fourth‑generation family business with 80+ years of engineering experience. Our engineers have trained at the factories of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). That depth of technical grounding shows up in cleaner integrations, smarter sequences of operation, and faster, more accurate diagnostics.

Healthy air is our mission

Healthy air drives healthy buildings. We design BMS strategies that stabilize indoor air quality while controlling energy use: demand‑controlled ventilation, advanced filtration strategies, and accurate sensor networks that keep fresh air and comfort consistent across zones.

• CO2‑based ventilation control aligned with occupancy
• Filtration strategies (e.g., MERV upgrades) coordinated with fan performance
• Zone balance checks to reduce hot/cold complaints
• Trend‑based IAQ analytics for proactive adjustments

Compliance, documentation, and training

We document sequences of operation, produce submittals, and ensure alignment with Title 24 and ASHRAE best practices. After commissioning, we train your staff with clear graphics and SOPs so day‑to‑day operations remain smooth.

• Title 24 controls requirements and acceptance testing support
• ASHRAE 62.1 ventilation and 90.1 energy best practices
• Network architecture, naming standards, and point lists
• Operator training, checklists, and quick‑start guides

Retrofit and integration without disruption

We specialize in phased BMS upgrades that minimize tenant impact. Our engineers plan cutovers, perform off‑hour work where needed, and validate each step with point‑to‑point checks and trend verification.

• System surveys and data logging to establish baselines
• Root‑cause analysis before programming—no guesswork
• Clear migration paths from legacy controls

Services tailored to your building

Whether you need a new BMS, an integration layer for multi‑vendor devices, or maintenance for an underperforming system, we tailor services to your building’s goals and budget.

• New construction: design‑assist, controls submittals, commissioning
• Existing buildings: re‑tuning, graphics refresh, alarming strategy
• Enterprise portfolios: standards, templates, and repeatable sequences
• Ongoing support: preventative maintenance, remote monitoring, and priority dispatch
