Commercial Industrial Exhaust Systems in Fontana

#1 AC Guys designs, installs, and services commercial industrial exhaust systems in Fontana with a singular focus: healthy air for safer, more productive facilities. From high-heat, high-particulate processes to grease-laden kitchen exhaust and solvent or VOC capture, we build Carrier-compatible solutions that balance airflow, stabilize pressure, and meet stringent California codes without sacrificing energy performance.

What we deliver

• Design-build industrial exhaust systems (process, general, and source capture)
• Make-up air integration with Carrier RTUs/AHUs and economizers
• Kitchen exhaust: Type I/II hoods, grease ducts, fans, and pollution control units
• Paint booth and finishing exhaust with filtration and airflow verification
• Welding, fume, and dust extraction, including spark-resistant fans
• Hazardous duty/explosion-resistant fans and controls where required
• Demand-controlled ventilation with CO/NO2/PM sensing and VFDs
• Building automation integration (BACnet/Modbus), alarms, and monitoring
• Permits, Title 24 documentation, and full TAB/commissioning
• Preventive maintenance, cleaning, and 24/7 emergency repair

Our fourth-generation family of engineers brings 80+ years of engineering experience to every project. We are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That foundation helps us solve complex airflow, controls, and integration challenges quickly and correctly.

Engineering and compliance

We design to IMC, NFPA 91/96, ASHRAE 62.1/90.1, California Title 24, and applicable SCAQMD guidance. Where needed, we apply CFD-informed airflow modeling to validate capture velocity, throw, and dilution strategies. Duct sizing considers static pressure, leakage class, and sound. We specify correct fan curves, belts or direct-drive, and VFD turndown to maintain performance across operating conditions.

• Code-driven details: clearances, fire/smoke dampers, roof penetrations, seismic bracing
• Grease duct design: welded construction, fire-rated enclosures, cleanouts, slope, and drains
• Filtration and abatement: baffles, cartridges, HEPA, carbon, electrostatic, and scrubbers
• Pressure management: coordinated exhaust and make-up air to prevent back-drafting
• Energy optimization: heat recovery, demand-control, and economizer logic

Kitchens follow NFPA 96 best practices; industrial exhaust adheres to NFPA 91 and process-specific standards. We prepare submittals, pull permits, coordinate inspections, and deliver closeout packages with as-builts, O&M, and TAB reports.

Carrier compatibility

Many Fontana facilities rely on Carrier rooftop units and air handlers. We integrate exhaust and make-up air so Carrier equipment operates in its sweet spot: proper return/exhaust offsets, economizer sequencing, and VFD control to maintain setpoints. We support BACnet/Modbus connectivity, demand-controlled ventilation, and alarm strategies—without claiming or requiring special dealership status. Our goal is smooth interoperability and long-term reliability.

• Carrier RTU/AHU integration with exhaust interlocks and safeties
• Curb adapters, roof rails, and vibration isolation
• Startup, commissioning, and trend-based verification

Industries we serve in and around Fontana

• Restaurants, food processing, and commercial kitchens
• Distribution and logistics warehouses with high-bay ventilation needs
• Manufacturing: metalwork, plastics, woodworking, and composites
• Automotive and aerospace: welding, grinding, and paint/finish booths
• Laboratories, R&D, and light pharmaceutical with local exhaust
• Cannabis cultivation and extraction with odor/VOC management

Whether you operate near Citrus Ave., Valley Blvd., or the I‑10/I‑15 corridor, we provide rapid, professional service scaled to your facility’s hours and production demands.

Installation and commissioning

Our crews handle rigging, roof penetrations, and duct routing with safety-first procedures and California seismic requirements in mind. We align sheaves and belts, set VFD parameters, verify rotation and balance, and insulate/flash for weather-tightness. Commissioning includes airflow measurements, capture tests, and controls sequencing. A final TAB report documents static pressure, cfm, and setpoints so your team has a clear operational baseline.

Maintenance that prevents downtime

• Routine cleaning of hoods, baffles, ducts, fans, and PCUs per NFPA schedules
• Bearing lubrication, belt tensioning, and vibration checks
• Filter changeouts and pressure-drop trending
• Control calibration and alarm verification
• Airflow recalibration after process or staffing changes

We offer planned service agreements tailored to usage—ideal for kitchens, multi-shift production, and seasonal operations. 24/7 emergency support is available for critical processes.
