Commercial Ventilation System Installation in Los Angeles

Why Los Angeles Businesses Choose #1 AC Guys

Healthy air drives productivity, safety, and code compliance. Our mission is simple: healthier indoor air for a healthier life and workplace. As a fourth‑generation family of engineers with 80+ years in engineering, we specialize in Commercial Ventilation System Installation across Los Angeles and nearby counties. From complex high‑rise core-and-shell to tenant improvements, we deliver engineered ventilation that meets performance targets and budget.

• Design‑build engineering with detailed ventilation and load calculations
• Title 24, CALGreen, and ASHRAE 62.1 compliance baked in from day one
• DOAS, ERV/HRV, and demand‑controlled ventilation (CO2‑based) for energy savings
• Kitchen hood and make‑up air systems for restaurants and commercial kitchens
• Parking garage exhaust with CO/NO2 sensors and variable speed control
• Laboratory and specialty exhaust with proper dilution and capture velocities
• High‑efficiency filtration (MERV/HEPA), UV‑C options, and air quality monitoring
• SMACNA‑grade ductwork, seismic bracing, and vibration control
• BAS/BMS controls integration (BACnet/Modbus), scheduling, and trending
• Commissioning and Test & Balance (TAB) for verified performance

Our engineers are factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This depth of training enhances our ability to integrate ventilation with VRF/ductless and central systems from those manufacturers for superior efficiency and control.

Our Process for Commercial Ventilation System Installation

1. Consultation & Site Survey: We review occupancy, processes, local code triggers, and mechanical constraints. We document existing equipment, duct paths, and electrical/seismic requirements.
2. Engineering & Design: Ventilation rates per ASHRAE 62.1, diversity factors, and demand control strategies are defined. We model DOAS/ERV/HRV options and select fans, duct sizes, and filtration tailored to your space.
3. Permits & Title 24: We prepare drawings and Title 24 forms, coordinate with city/county reviewers, and plan for inspections.
4. Installation: SMACNA‑compliant ductwork, proper clearances, fire/smoke damper placement, seismic bracing, and controls wiring. We coordinate with other trades to minimize downtime.
5. Commissioning & TAB: Airflow is measured and balanced, sensors are calibrated, alarms verified, and sequences of operation tested.
6. Turnover & Training: You receive O&M documentation, as‑builts, and training for facilities staff.

Systems We Engineer and Install

• DOAS (Dedicated Outdoor Air Systems): Supplies conditioned ventilation air independent of space conditioning for consistent IAQ.
• ERV/HRV: Energy recovery that reduces heating/cooling loads while meeting ventilation requirements.
• Demand‑Controlled Ventilation: CO2/VOC sensor‑based airflow to match occupancy and cut energy costs.
• Kitchen Hood & Make‑Up Air: Proper capture, make‑up air tempering, and interlocks to protect guests and staff.
• Parking Garage Exhaust: Sensor‑driven VFD control to maintain safe levels and lower utility bills.
• Filtration & Air Quality: MERV upgrades, HEPA zones, UV‑C, and continuous IAQ monitoring dashboards.

Codes, Standards, and Documentation

We design to ASHRAE 62.1 ventilation rates, Title 24 energy requirements, CALGreen sustainability measures, SMACNA duct construction standards, and applicable NFPA and local fire codes. We align with Cal/OSHA guidance for safe operations. Every project includes submittals, sequences of operation, commissioning checklists, and TAB reports to make inspections and handover smooth.

Industries We Serve

Office and creative spaces, retail and mixed‑use, restaurants and commercial kitchens, warehouses and light industrial, schools and training centers, healthcare outpatient and dental, labs and specialty suites, and more. If your Los Angeles property requires Commercial Ventilation System Installation, our engineers will tailor a solution to your occupancy, budget, and schedule.

Service Area

We proudly serve Los Angeles County and nearby regions, including Orange County, Ventura County, and Western Riverside County. Urban infill, historic retrofits, or new construction—our team understands local jurisdictions and inspection workflows to keep your project moving.
