Commercial Control Systems in Rialto

When your Rialto facility depends on predictable comfort, clean air, and measurable savings, you need commercial control systems built by engineers. #1 AC Guys unites 80+ years of engineering experience with modern BAS/DDC, giving you reliable automation, insightful analytics, and the flexibility to grow.

What we deliver

• Design and programming of BAS/DDC architectures that match your equipment and operational goals
• Open‑protocol integration (BACnet, Modbus) for multi‑vendor systems and phased retrofits
• Optimized sequences of operation for comfort, energy, and indoor air quality
• Dashboards, alarming, and remote access for fast decisions and fewer site visits
• Commissioning and retro‑commissioning to verify performance and document results
• Ongoing monitoring and tune‑ups to keep savings locked in

An engineering‑first approach

Our fourth‑generation family team treats HVAC controls as a precision engineering discipline. We start with a detailed site assessment, load and airflow considerations, and equipment mapping. Then we develop control drawings, points lists, and sequences tailored to your occupancy patterns, ventilation needs, and utility rates. The result is a stable, scalable system that’s easy to operate and simple to maintain.

Factory training that matters

Our engineers have trained at the factories of Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That means we understand how to integrate controls with these platforms—VRF/mini‑split, rooftop, and supporting components—so you get the efficiency and reliability the equipment was built to deliver.

Typical control solutions

• VRF/mini‑split integration with centralized scheduling, setpoint management, and trend logs
• Rooftop unit controls with demand ventilation, economizer logic, and CO2‑based IAQ strategies
• Zoning and VAV/VVT control for balanced comfort across changing occupancies
• Boiler/chiller plant optimization with resets, lead/lag, and pump/VFD coordination
• Energy monitoring, utility demand limiting, and fault detection diagnostics
• Filtration and IAQ sensors (PM2.5, VOC, CO2) with actionable alerts and reports

Compliance and documentation

We help owners and GCs meet California Title 24 and local codes with proper sequences, acceptance testing support, and turnover documents your team can actually use. Clear labeling, as‑built drawings, and training sessions reduce downtime and speed up maintenance.

Industries we support

Offices and campuses, retail and restaurants, healthcare clinics, light manufacturing, logistics and warehouses, education, hospitality, and community facilities. If your site needs stable temperatures, healthier air, and energy accountability, we can design the controls to deliver.

Project workflow

• Discovery: goals, pain points, utility review, and IAQ priorities
• Engineering: control drawings, points list, network topology, and sequences
• Installation: panels, sensors, networking, and safe cutover planning
• Commissioning: functional testing, trend validation, and acceptance support
• Optimization: fine‑tuning schedules, resets, and alarms based on real data
• Lifecycle care: periodic audits, training refreshers, and upgrade paths

Service area and response

We are based in Los Angeles and serve Rialto and neighboring communities across Los Angeles County, Orange County, Ventura County, and Western Riverside County. Our crews are accustomed to complex, occupied retrofits and fast‑track schedules along the I‑10 corridor—minimizing disruption while maximizing results.
