Commercial Ventilation System Installation in Los Angeles (Fujitsu‑Trained)

When air quality, comfort, and compliance matter, #1 AC Guys delivers commercial ventilation systems engineered for Los Angeles buildings. We start with load calculations, airflow modeling, and code analysis, then design a right‑sized solution that keeps your occupants healthy and your operation efficient.

Fujitsu‑Trained Expertise, Built for Complex Projects

Our engineers are factory‑trained by Fujitsu (Japan) and bring deep knowledge of integrating ventilation with high‑efficiency systems. From VRF/mini‑split integration to dedicated outdoor air systems (DOAS) and energy recovery ventilators (ERVs), we build solutions that balance fresh air intake, exhaust, and building pressure while minimizing energy penalties.

We also bring manufacturer training from Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), enabling precise commissioning and controls that play nicely with your broader mechanical design.

What We Install

• Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) for balanced fresh air and energy savings
• Dedicated Outdoor Air Systems (DOAS) to decouple ventilation from space conditioning
• Demand‑controlled ventilation (CO₂/VOC‑based) to match airflow to occupancy
• High‑efficiency filtration (MERV 13+) and air cleaning strategies for IAQ
• Kitchen, restroom, and process exhaust with makeup air and building pressure control
• Controls integration with BMS/EMS and Fujitsu‑compatible interfaces

Compliance, Safety, and Documentation

Los Angeles projects require careful coordination and documentation. We engineer to:

• ASHRAE 62.1 ventilation rates and IAQ procedures
• California Title 24 and CALGreen requirements
• Local permitting, seismic supports, and fire/smoke code clearances
• Commissioning and TAB reports for turnover and records

Expect sealed drawings, submittals, and closeout packages aligned with your GC and facility standards.

Our Engineering‑Led Process

• Discovery and site assessment: use, occupancy, and constraints
• Airflow and load modeling: demand profiles, pressure, and zoning
• System selection: ERV/DOAS, filtration, controls, and distribution
• Coordination: structural, electrical, and architectural reviews
• Installation: safety‑first execution with clear milestones
• Commissioning and TAB: verify flows, controls, and documentation
• Training and turnover: facility staff onboarding and O&M
