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

What We Do for Commercial Buildings in Ontario, CA

We design and deliver Building Management Systems that centralize HVAC, ventilation, and indoor air quality data into one secure, actionable platform. Whether you operate an office near Historic Downtown Ontario, a distribution center by Ontario International Airport, or a mixed‑use site along I‑10 and SR‑60, our BMS solutions scale to your footprint and growth plans.

• Turnkey BMS design, drawings, and submittals
• New build and retrofit controls installation
• Integration with AC PRO‑compatible equipment
• BACnet/IP, BACnet MS/TP, and Modbus integration
• Commissioning, point‑to‑point testing, and reports
• Remote monitoring, analytics, and alarm management
• Preventive maintenance and lifecycle service

Open Protocols and Future‑Ready Architecture

We prioritize open standards so you can expand without lock‑in. Using BACnet and Modbus, we connect packaged units, VRF/mini‑split systems, boilers, VAVs, and IAQ sensors into a unified BMS. Dashboards visualize trends, energy usage, and comfort indexes, while role‑based access keeps your operations secure. We can segment OT networks, implement user policies, and provide secure remote access for authorized stakeholders.

AC PRO Integration and Major Manufacturers

As an engineering‑first contractor, we integrate controls with AC PRO‑sourced commercial HVAC equipment and components to meet design intent and performance targets. Our engineers have trained at manufacturers’ facilities with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), enabling precise integration and commissioning of sophisticated systems while adhering to factory best practices and local code requirements.

Healthy Air Is Our Mission

Healthier buildings perform better. Our BMS strategies combine ventilation control, demand‑control logic, and air quality monitoring to maintain cleaner, safer indoor environments—supporting productivity and occupant well‑being.

• IAQ monitoring: CO2, PM2.5, TVOC, temperature, and humidity
• Smart ventilation aligned with ASHRAE 62.1
• Filtration and purification control strategies
• Humidity management to reduce pathogen survival
• Alerts for out‑of‑range IAQ events and rapid response

We document settings and sequences to support compliance with Title 24, local permitting, and sustainability frameworks such as CALGreen and LEED prerequisites.

Frequently Asked Questions

• What is a BMS? A Building Management System is a platform that monitors and controls building equipment—HVAC, ventilation, and IAQ—improving comfort, health, and energy efficiency.
• Can you integrate with our existing equipment? Yes. We work with open protocols (BACnet/Modbus) and integrate with AC PRO‑compatible systems, VRF/mini‑split, and packaged units from leading manufacturers.
• How fast can you start? After a site walk and scope alignment, we provide a proposal within days and mobilize quickly based on lead times and operations windows.
• How do you prove ROI? Baseline and post‑commissioning trend data, IAQ metrics, and energy analytics demonstrate savings and comfort improvements.
• Are you licensed and insured? Yes—our family business stands behind every project with proper licensing, insurance, and documented safety practices.
