Commercial & Industrial Exhaust Systems in Orange, CA

End‑to‑end engineering for demanding exhaust applications

We specialize in design‑build and plan‑spec projects where performance, safety, and compliance cannot be compromised. Whether you need a brand‑new system or a retrofit that solves chronic heat, smoke, grease, odor, or fume problems, #1 AC Guys delivers clear calculations, clean installations, and reliable commissioning.

• Commercial kitchen exhaust per NFPA 96 with UL 762 grease exhaust fans
• Laboratory and R&D exhaust with proper stack height and dilution strategies
• Process ventilation for welding, solvents, composites, plastics, printing, and more
• General exhaust and heat relief for warehouses, manufacturing, and bakeries
• Makeup air units (MAU), tempered makeup air, and demand‑control ventilation
• Smart controls, VFDs, interlocks, and building automation integration
• Testing, adjusting, and balancing (TAB) for guaranteed airflow

What we design and build

Every facility is different. Our engineers evaluate loads, contaminants, pathways, sound, vibration, and energy use before we recommend a solution. We model capture velocity, hood face velocity, duct friction, and system effect to ensure the installed system performs as designed.

• Engineered duct systems: welded black steel for grease, stainless 304/316, galvanized, aluminum, and FRP/PVC for corrosive exhaust
• Fans and stacks: AMCA‑rated roof upblast, inline, and high‑plume lab stacks with rain protection and dilution nozzles
• Hoods: canopy, backshelf, proximity, and custom capture devices for unique processes
• Controls: DCKV (demand‑control kitchen ventilation), pressure monitoring, airflow proving, and safety interlocks
• Noise and vibration: isolation bases, flexible connectors, and silencers designed from submittals, not guesswork

Compliance and permits—handled

We coordinate with local authorities to streamline approvals and inspections. Our drawings, cut sheets, and calculations are packaged for reviewers so your project stays on schedule.

• California codes: CMC/IMC, CBC, Title 24, CALGreen
• Standards: NFPA 96, UL 762, UL 705 where applicable
• Air quality: South Coast AQMD permitting and documentation
• Fire authority: hood suppression coordination and access/clearance details

When specified, we source premium materials and hardware through AC PRO to meet submittal requirements and keep logistics tight. Our supply chain helps reduce lead times and keeps critical parts available during construction and service.
