Commercial Ventilation Design in Rialto

When your facility in Rialto needs Commercial Ventilation Design that puts occupant health, compliance, and energy performance first, #1 AC Guys is the engineering partner you can trust. We are a 4th‑generation family of engineers with 80+ years in engineering, focused on designing and delivering ventilation systems that solve complex airflow challenges while meeting schedule and budget.

What we design

• Office and retail ventilation with demand‑controlled strategies
• Restaurant kitchens with code‑compliant exhaust and make‑up air
• Warehouse and distribution with high‑bay air movement and heat relief
• Light manufacturing and specialty exhaust for process areas
• Laboratories and healthcare support areas with pressure control
• Education and assembly spaces optimized for acoustics and IAQ
• Server rooms and telecom spaces with targeted ventilation support
• Multifamily common areas and mixed‑use commercial cores

Every design is tailored to ASHRAE 62.1/62.2 ventilation rates, California Title 24 energy requirements, and local code enforcement expectations in the Inland Empire and Greater Los Angeles region.

Our engineering process

We start with a site assessment and clear design brief: occupancy profiles, pollutant sources, process loads, and envelope conditions. Next, we perform load and airflow calculations, evaluate exhaust sources, and right‑size outdoor air, ERV/HRV, and filtration. We model fan curves and duct static to reduce horsepower and noise, then produce coordinated drawings and specifications that installers can price accurately.

• Field survey and data capture, including existing equipment and utilities
• Ventilation and exhaust calculations, diversity factors, and zoning
• Duct routing to minimize losses and future maintenance conflicts
• Filtration and IAQ strategy: MERV levels, carbon, UV‑C where appropriate
• Controls sequences for demand‑controlled ventilation and economizers
• Submittal review, permitting support, and commissioning plans

Need fast procurement? We can specify equipment and components commonly available through AC PRO to keep lead times predictable without compromising performance.

Why #1 AC Guys

• 4th‑generation family business with 80+ years in engineering
• Factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China)
• Deep expertise in large, complex commercial projects
• Design‑Build friendly packages: drawings, schedules, and scopes that bid cleanly
• Lifecycle cost focus: energy recovery, right‑sized fans, smart controls
• Safety and uptime: redundancy strategies where your operation demands it

Our mission is healthy air for a healthy life. That means we design systems that manage contaminants, control humidity, and deliver the right outdoor air—without wasting energy.

Compliance and health

We align designs with ASHRAE 62.1/62.2, California Title 24, local mechanical codes, and best practices for indoor air quality. We size ventilation to real usage patterns and incorporate demand control to respond to occupancy, CO₂, VOCs, or PM as required. Where appropriate, we integrate ERV/HRV for heat and moisture recovery, and we specify filtration strategies that balance IAQ with fan energy.

For food service, we provide kitchen exhaust sizing, grease duct routing, hood selection, and make‑up air that stabilizes pressure and comfort. For warehouses, we optimize air movement, destratification, and relief ventilation to reduce hot spots and improve productivity.

Materials, equipment, and sourcing

To streamline delivery, we can select components and equipment available through AC PRO, helping your project move from design to installation with fewer surprises. Our engineers are factory‑trained by Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier—training completed at the manufacturers’ facilities in Japan, Thailand, and China—so we understand how to integrate equipment characteristics into efficient, durable ventilation solutions.

Service area and response

We serve Rialto and the Greater Los Angeles area, including Los Angeles County and nearby regions such as Orange County, Ventura County, and Western Riverside County. If your project spans multiple sites across the Inland Empire or LA Basin, we can standardize specifications for consistent performance and maintenance.

Typical project flow:
1) Discovery and site visit
2) Calculations and schematic concept
3) Coordination with owner/GC and cost plan
4) Final drawings, controls, and specifications
5) Submittals, permit support, and commissioning
