Commercial Ventilation System Installation in Rialto, CA

#1 AC Guys is the engineering‑led partner Rialto businesses trust for commercial ventilation system installation that improves indoor air quality, meets code, and reduces life‑cycle costs. From rooftop intakes to the last diffuser, our team designs and installs systems that deliver the right air, in the right place, at the right time.

Engineering‑Led Design for Reliable IAQ

Backed by 80+ years of engineering expertise across four generations, we start with the fundamentals: occupancy and process loads, contaminant sources, pressure relationships, duct velocities, noise criteria, energy recovery potential, and controls strategy. The result is a ventilation system that balances comfort, safety, and efficiency for Rialto’s diverse commercial environments.

Systems We Install

• Dedicated Outdoor Air Systems (DOAS) with energy recovery for decoupled ventilation and humidity control.
• Energy/Heat Recovery Ventilators (ERV/HRV) to reduce conditioning loads while maintaining fresh air rates.
• Make‑Up Air Units sized for kitchens, manufacturing spaces, and large exhaust applications.
• Commercial Exhaust: kitchen hoods and grease ducts, restroom and general exhaust, garage CO/NO2 exhaust, and specialty process exhaust.
• Filtration upgrades: MERV 13–16 and HEPA (where required), plus optional UV‑C for coil and airstream treatment.
• Demand‑Controlled Ventilation using CO2 and occupancy sensors for dynamic airflow and energy savings.
• Variable‑speed fans with VFDs, sound attenuation, and airflow measurement stations for accurate balancing.

Our Process: From Assessment to Commissioning

• On‑site assessment in Rialto: review floor plans, operations, and IAQ goals; measure existing airflow where applicable.
• Calculations and code: ventilation rates per use type, pressure zoning, Title 24, IMC/CMC compliance, and local permitting support.
• Design & coordination: CAD/BIM layouts, collision checks, roof/structure coordination, and submittal packages.
• Professional installation: sealed and insulated ductwork, airtight penetrations, curb and seismic details, and proper condensate management.
• Testing, Adjusting, and Balancing (TAB): verify CFM, pressures, sound, and controls sequences; duct leakage testing as needed.
• Controls integration: BMS interfaces, CO2/DCV logic, scheduling, alarm points, and remote monitoring options.
• Startup & training: manufacturer start‑up procedures, O&M documentation, and staff training for maintenance.

Healthier Air, Lower Operating Cost

Well‑designed ventilation reduces contaminants and moisture, mitigates odors, protects products and equipment, and supports occupant wellbeing. With ERV/DOAS and demand control, many facilities cut energy use while achieving consistent fresh air delivery. We also prioritize access for maintenance, so filters, belts, and coils can be serviced quickly—helping your system stay efficient year after year.

Factory‑Trained Specialists

Our engineers and installers have completed factory training with global manufacturers including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This training supports accurate selection, installation, and startup of advanced ventilation and HVAC equipment used in commercial projects.
