Commercial & Industrial Exhaust Systems in Los Angeles — Lennox Integration

End-to-End Exhaust Solutions for Demanding Commercial Environments

We engineer Commercial and Industrial Exhaust Systems that move air efficiently, safely, and quietly. From commercial kitchen exhaust and grease fans to fume extraction, general exhaust, smoke control strategies, and garage ventilation, our designs are built for code compliance, uptime, and measurable performance.

Our 4th‑generation engineering team delivers design-build services, permitting support, installation, commissioning, test & balance, and preventive maintenance—so you get one accountable partner from concept through warranty and beyond.

Lennox-Integrated Ventilation That Saves Energy

We integrate exhaust airflow with Lennox rooftop units and controls to coordinate economizers, makeup air, and demand-controlled ventilation. The result: stable building pressure, better indoor air quality, and lower utility costs. Whether you run Lennox RTUs, split systems, or packaged units, we optimize controls and airflow so exhaust, supply, and return work in sync.

• Demand-controlled ventilation tied to occupancy and CO₂
• Makeup air sizing and tempering for safe, balanced spaces
• ERV/HRV options to recover energy from exhaust airstreams
• VFD-driven exhaust fans for quiet, efficient modulation
• Integration with BMS/BAS for trending and alarms

Where We Excel

• Commercial kitchens: grease duct, fans, hoods, makeup air, and NFPA 96 best practices
• Manufacturing and warehouses: particulate, heat, and process exhaust with air changes optimized for comfort and safety
• Laboratories and R&D: directional airflow strategies, exhaust dilution, and precise control
• Parking structures: CO/NOx monitoring, demand ventilation, and code compliance
• High-rises and mixed-use: shafted exhaust, stair pressurization strategies, and rooftop integrations
