Commercial Exhaust Fans in Fontana, CA

Built for Fontana Facilities

Fontana businesses rely on robust ventilation to control heat, fumes, smoke, grease, odors, and airborne contaminants. #1 AC Guys delivers commercial exhaust fan systems that protect air quality, meet code, and lower operating costs. As a 4th‑generation family business with 80+ years of engineering expertise, we combine field‑proven design with precision installation and maintenance you can trust.

What We Do

• Design & Sizing: Fan selection by CFM and static pressure, proper duct sizing, and make‑up air so your system breathes, not struggles.
• Installation & Replacement: Roof‑ and wall‑mounted centrifugal, upblast, inline, and utility fans; curb adapters; grease ducts; hoods; and controls.
• Repairs & 24/7 Emergency Service: Motors, bearings, belts, wheels, shafts, vibration issues, electrical, VFDs, sensors, and controls—fast turnaround to minimize downtime.
• Air Balancing & Commissioning: Verify airflow, pressures, capture velocity, and makeup‑air balance for quiet, efficient performance.
• Preventive Maintenance: Cleaning, lubrication, belt tension, filter service, and performance checks that extend equipment life and maintain compliance.

Code, Safety & Compliance

We build systems to meet IMC/UMC, NFPA 96 for commercial cooking, California Title 24, Cal/OSHA, and local jurisdiction requirements. From grease‑rated upblast fans and listed hoods to interlocks, fire suppression tie‑ins, and rooftop clearances, our installations are permit‑ready and inspection‑ready. We also help with AQMD considerations and documentation your AHJ expects.

Industries We Serve

• Restaurants, ghost kitchens, cafeterias (grease hoods, upblast fans, demand control ventilation).
• Warehouses, logistics hubs, and manufacturing (heat and fume exhaust, staged fans, VFDs).
• Auto body and repair shops (VOC, welding, and tailpipe extraction).
• Food processing and cold storage (corrosion‑resistant fans, wash‑down, NSF considerations).
• Labs, cannabis/grow, healthcare, and wellness (filtration, pressure relationships, odor control).
• Retail, offices, schools, fitness, and hospitality (restroom and general exhaust).

Brands & Technology

Our engineers are factory‑trained by global manufacturers including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier (China), and we service leading exhaust and hood brands such as Greenheck, CaptiveAire, Loren Cook, PennBarry, Systemair, and Twin City Fan. We integrate smart controls, demand‑controlled ventilation, and VFDs to cut energy use while maintaining target capture and comfort.

Our Process

1) Site Assessment: We survey existing equipment, duct paths, hood types, heat and contaminant loads, and utility access.
2) Engineering & Proposal: You get a clear scope with equipment schedule, CFM and static calculations, controls, and code references—no guesswork.
3) Permits & Scheduling: We handle submittals, permits, and coordination with GC, roofing, and fire suppression teams when needed.
4) Installation & Commissioning: Clean, safe, on‑schedule install; start‑up, balancing, and documentation for inspections and warranty.
5) Ongoing Service: Priority maintenance and 24/7 support to keep uptime high and costs predictable.

Performance You Can Measure

Exhaust systems succeed when CFM and capture are right, noise is controlled, and energy bills stay in check. We optimize fan curves, static pressure, duct layout, and makeup air to prevent negative building pressure, door drafting, and odor or grease fallout—then verify with instruments so you see the results, not just hear promises.

Service Area & Response
