Commercial & Industrial Exhaust Systems in Los Angeles

At #1 AC Guys, we build commercial and industrial exhaust systems that protect people, processes, and property—engineered for Southern California codes and real‑world conditions. Whether you need a new system, a retrofit to meet current standards, or performance tuning for energy savings, our team delivers precise airflow and dependable uptime.

What we do

• Design and engineering: load calculations, airflow modeling, and CAD documentation
• Installation and retrofit: fans, hoods, ductwork (grease, double‑wall, corrosion‑resistant), make‑up air, and controls
• Commissioning and air balancing: verify capture, pressure, and code performance
• Maintenance and repairs: bearings, belts, motors, VFDs, sensors, PCUs, and duct integrity
• Energy optimization: demand control ventilation, VFD tuning, heat recovery, and controls integration

We integrate proven components—including AC PRO–supplied equipment—so your system is serviceable, parts‑available, and built for long‑term reliability.

Systems we engineer

• Commercial kitchen exhaust (NFPA 96): UL 762/705 fans, listed grease duct, make‑up air, hoods, and PCUs
• General industrial exhaust: heat, smoke, welding fumes, solvents, and process vapors
• Laboratory and specialty exhaust: fume hoods, canopy hoods, dedicated exhaust risers
• Parking garage exhaust: CO/NO2 dilution control with demand‑based ventilation
• Warehouse/process ventilation: high‑volume exhaust, destratification, and tempered make‑up air

Our mission is healthier indoor air for a healthier life—delivered with engineering discipline and practical field experience.

Engineering‑first compliance

We design and install exhaust systems to meet California Mechanical Code (CMC), Title 24 energy standards, NFPA 96 for commercial kitchens, IMC, OSHA, and local AQMD rules. We coordinate with plan reviewers and inspectors, manage permits, and commission systems so you pass the first time.
Expect clear submittals, sealed drawings when required, and documented test results for airflow, static pressure, capture velocity, and make‑up air balance.

Components and integrations

We specify and install exhaust fans, make‑up air units, grease duct and access panels, corrosion‑resistant duct, pollution control units, VFDs, actuators, dampers, EC/PM motors, and smart controls. We integrate with your BMS where needed and source serviceable parts—including AC PRO components—to keep maintenance simple and downtime short.
Our factory‑trained HVAC team (Fujitsu – Japan, Mitsubishi Electric – Thailand, Midea, Gree, Hier) ensures exhaust and supply air work together for comfort, pressure control, and energy efficiency.

Our process

• Site assessment and code review: document loads, hazards, and compliance gaps
• Engineering and proposal: detailed scope, drawings, airflow targets, and timeline
• Permitting and procurement: coordinate AHJ submittals and source AC PRO–grade parts
• Installation: safe, clean, and sequenced to minimize downtime
• Commissioning and training: verify performance; train your staff on operation and safety
• Maintenance plan: scheduled inspections, cleaning, and predictive repairs
