Commercial & Industrial Exhaust Systems in Fontana

Why #1 AC Guys for Fontana exhaust systems

We are a family-run, fourth-generation team with 80+ years of engineering heritage, trusted on large, complex projects across Southern California. Our mission is healthy air for a healthy life, delivered through precise design, careful installation, and rigorous commissioning. Our engineers are factory-trained by Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier, and we integrate that engineering discipline into every ventilation and exhaust solution we build.

We proudly serve Fontana and the surrounding region from Greater Los Angeles to nearby Inland Empire communities, Orange County, Ventura County, and Western Riverside County.

What we design, install, and service

• Industrial exhaust: welding fume extraction, grinding and dust capture, vehicle and forklift exhaust, paint and chemical exhaust, battery room venting
• Commercial exhaust: kitchen hood systems (Type I and II), restroom and locker room exhaust, parking garage CO and NO2 exhaust
• Make-up air and pressure control: tempered make-up air units, dedicated outside air, demand-control ventilation with sensors
• Ductwork and accessories: stainless, galvanized, and coated steel; spark-resistant fans; corrosion-resistant materials; sound attenuation
• Controls and efficiency: VFDs, BAS integration, airflow monitoring stations, energy recovery where applicable

AC PRO component advantage

We specify and source AC PRO industrial exhaust fans, make-up air equipment, hoods, and accessories to accelerate lead times, streamline warranty support, and ensure parts availability. That means faster installs, easier maintenance, and proven performance backed by a robust supply chain.

Design-build process that lowers risk

Every project starts with a site assessment and airflow audit. We document processes, contaminants, heat loads, and duty cycles, then calculate required capture velocities, transport velocities, and system losses. Using manufacturer fan curves and SMACNA standards, we size ductwork, select fans, and set control sequences to balance code compliance, occupant safety, and energy cost.

• Assessment and code path: IMC, NFPA 91 for industrial ventilation, NFPA 96 for commercial kitchens, and OSHA considerations
• Engineering: hood and capture device selection, duct sizing, materials, fan selection, vibration isolation, and noise control
• Controls: VFD tuning, occupancy and contaminant sensors, BAS integration, alarm strategies
• Build: fabrication, installation, sealing and insulation, fire and smoke protection where required
• Commissioning: testing and balancing, airflow verification, sensor calibration, and training your team

Compliance, safety, and documentation

We coordinate with your AHJ, prepare submittals, and deliver as-builts, O&M manuals, and balancing reports. For facilities in the South Coast region, we also assist with air quality considerations to help align with local requirements. Our goal is a smooth approval process and a reliable, inspectable system on day one.

Retrofits and energy optimization

If your current exhaust is noisy, underperforming, or too costly to run, we can retrofit with properly sized AC PRO fans, tighter duct systems, and VFD-driven controls. Demand-control ventilation reduces run time when contaminant or occupancy levels are low, while improved capture at source lets you move less air overall without sacrificing safety. Where appropriate, we apply energy recovery and high-efficiency motors to reduce utility spend and improve comfort.
