Commercial Ventilation System Installation in Los Angeles — Lennox

Engineering‑first ventilation for healthier, more efficient buildings

At #1 AC Guys, every commercial ventilation system starts with your air quality, occupancy, and code requirements—not a catalog page. We evaluate your space, loads, and usage patterns, then design a Lennox‑centered solution that delivers balanced, filtered, and properly tempered outdoor air with verifiable performance.

Our 4th‑generation family of engineers brings 80+ years of engineering expertise to complex builds and retrofits. Our team has completed factory training with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China), applying rigorous standards and commissioning habits to every brand we install or integrate, including Lennox commercial ventilation.

What we install and integrate

• Lennox‑based commercial ventilation systems: ERV/HRV and DOAS configurations for continuous fresh air
• Make‑up air units for kitchens and process spaces, with modulating control
• Demand‑control ventilation using CO₂/VOC sensors to reduce energy use during partial occupancy
• MERV 13+ filtration upgrades and filter rack retrofits to elevate IAQ
• Economizer integration, outdoor air dampers, and relief strategies
• Ductwork design/build, curb adapters, seismic supports, and vibration isolation
• Controls integration (BACnet/Modbus), BMS tie‑ins, and remote monitoring

Every install is commissioned and air‑balanced to confirm airflow, pressure, and ventilation rates match the design intent.

A proven process for busy commercial sites

• Site assessment and airflow testing to benchmark current conditions
• Engineering and design‑build with detailed submittals and coordination drawings
• Permitting and inspector coordination, including Title 24 documentation
• Installation with safety planning, clean work zones, and minimal downtime
• Controls setup and point‑to‑point verification for stable operation
• Commissioning and air balancing aligned with design and code targets

Need to maintain operations? We can schedule phased, night, or weekend work to keep your business running.

Compliance and clean air, without the guesswork

We design for California Title 24 and ASHRAE 62.1 ventilation requirements, with attention to CalGreen and local AHJ interpretations. From fire/smoke damper placement to economizer logic and CO₂ setpoints, our documentation and testing help you pass inspections and achieve consistent indoor air quality.

For facilities targeting wellness, we implement MERV 13+ filtration, proven dilution/ventilation rates, and demand‑control strategies that cut energy use while maintaining compliance.
