Commercial Exhaust Fans in Rialto, CA

#1 AC Guys is a family HVAC company built by four generations of engineers, delivering healthy air for healthy lives. In Rialto, we bring 80+ years of engineering experience to design, install, repair, and maintain commercial exhaust fans that protect people, property, and production while meeting code and reducing energy spend.

Why engineered exhaust matters in Rialto

Rialto facilities face real ventilation challenges: heat, fumes, grease vapor, particulates, and odors that impact worker safety and customer comfort. Properly engineered exhaust with matched make‑up air stabilizes pressure, improves indoor air quality, limits cross‑contamination, and protects equipment. The result is a safer, more productive building with fewer complaints and lower operating costs.

End‑to‑end services for commercial exhaust fans

• On‑site evaluation with CFM targets, static pressure calculations, and duct loss analysis
• Design‑build or plan‑spec execution with stamped submittals when required
• Permitting support and coordination with inspectors and health departments
• Installation, curb and roof penetrations, seismic anchorage, and waterproofing best practices
• Controls integration: VFDs, EC motors, sensors, interlocks, and demand control ventilation
• Air balancing, test and verification reports, and commissioning
• Diagnostics, repair, retrofit, and energy optimization
• Planned maintenance to extend life and prevent downtime

Systems we design, install, and service

• Commercial kitchen exhaust and make‑up air (Type I and II hoods, upblast and inline fans, grease duct, fire wrap)
• Warehouse and manufacturing exhaust (heat and smoke relief, process exhaust, spot capture)
• Parking garage exhaust with CO and NO2 demand control ventilation
• Restroom and general exhaust for offices, schools, and retail
• Laboratory and specialty exhaust with corrosion‑resistant materials where needed
• Smoke purge and stairwell pressurization interfaces with mechanical systems

Our engineering‑first approach

We right‑size equipment using fan curves, total equivalent duct length, and system effect to ensure your fans deliver specified CFM at design static pressure. We design for low sound levels, vibration control, and efficient routing that minimizes losses. Controls are set up for reliability and savings, including VFD turndown, occupancy schedules, and sensor‑based modulation. Every project is documented with clear scope, drawings, and startup reports.

• Precision airflow calculations and duct design that reduce noise and energy use
• Equipment selection for performance, maintainability, and future expansion
• Balanced make‑up air to prevent negative pressure and door drafting
• Startup checklists, training for your staff, and close‑out documentation

Code, safety, and compliance

We build to California Mechanical Code and Title 24, aligning with NFPA 96 for commercial kitchen systems and applicable OSHA and AQMD requirements. Our team coordinates submittals, clearances, wall and roof terminations, and fire protection interfaces. You get a compliant, inspectable system with the paperwork to prove it.

Factory‑trained expertise

Our engineers are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This training, combined with decades of field experience, helps us integrate exhaust, make‑up air, and HVAC for stable temperatures, humidity, and pressure control across your facility.
