Commercial & Industrial Exhaust Systems in Los Angeles

#1 AC Guys is a family‑owned Los Angeles engineering firm specializing in commercial and industrial exhaust systems that meet demanding performance and compliance requirements. We serve Los Angeles County and nearby regions, including Orange County, Ventura County, and Western Riverside County, with design‑build delivery, retrofits, and ongoing maintenance tailored to your facility, process, and code environment.

What we do

• Design‑build exhaust systems for kitchens, manufacturing, labs, parking garages, warehouses, and high‑rise cores
• Industrial ventilation and fume extraction with proper capture, containment, and dilution strategies
• Make‑up air integration to stabilize building pressure and support safe exhaust performance
• Exhaust fan selection, VFD optimization, and noise/vibration mitigation
• Ductwork fabrication, grease duct upgrades, and corrosion‑resistant materials
• Balancing, testing, and commissioning with detailed reporting
• Controls, monitoring, and demand‑based ventilation for energy savings
• Preventive maintenance, compliance checks, and emergency repairs

Engineered for compliance and safety

Our systems are engineered to align with applicable standards and local authority requirements, including NFPA 96 for commercial cooking ventilation, the International Mechanical Code (IMC), California Title 24 energy standards, and regional air quality rules. We plan for clearances, access, fire protection interfaces, and documentation to streamline permits and inspections.

We provide sealed drawings, equipment submittals, and commissioning records to help your team demonstrate compliance and operational readiness. From capture hoods and canopy design to duct routing, fan curves, and termination strategies, every detail is calculated for reliable, code‑compliant airflow.

Industries we serve

• Restaurants, food halls, and commercial kitchens
• Manufacturing, fabrication, and light industrial facilities
• Laboratories, R&D, and tech spaces
• Parking structures and smoke control zones
• Warehouses, logistics centers, and distribution hubs
• Retail, mixed‑use, hospitality, and multi‑tenant properties

Design matters: performance you can measure

Effective exhaust is more than CFM. We model capture velocity, static pressure, system effect, and stack dispersion to ensure contaminant removal without over‑ventilating. Thoughtful make‑up air design prevents drafts, odor migration, and negative pressure that can disrupt doors, pilot lights, and process equipment.

Controls and sensors enable demand‑based ventilation, lowering energy use during off‑peak times while maintaining air quality. We right‑size fans, select efficient motors, and apply VFDs to reduce noise, extend equipment life, and achieve Title 24 goals.

Retrofits and upgrades

If your existing system struggles with smoke, heat, odors, or fume containment, we perform diagnostics, airflow testing, and thermal imaging to locate constraints. We then implement targeted upgrades—fan replacements, duct reconfiguration, hood modifications, grease management improvements, and control sequences—to deliver immediate, verifiable gains.

Commissioning and documentation

Every project is balanced and commissioned with a clear report: measured airflow, pressure, amp draw, vibration, and control setpoints. You get an asset register, O&M guidelines, and a preventive maintenance schedule to keep performance on spec and to support future inspections.

Service and maintenance

• Scheduled cleaning and inspection of hoods, fans, ducts, and filters
• Bearing, belt, and motor checks with vibration and temperature trends
• Airflow rebalancing after tenant improvements or equipment changes
• Emergency diagnostics and corrective repairs to minimize downtime
