Daikin Commercial Ventilation System Installation in Los Angeles

When your project calls for Daikin commercial ventilation in Los Angeles, #1 AC Guys delivers an engineer-led approach that raises the bar on performance, compliance, and occupant wellness. As a fourth-generation family business with 80+ years of engineering experience, we’re built for complex scopes, tight timelines, and mission-critical spaces where balanced airflow and continuous uptime matter.

Engineer-Led Design-Build for Complex Commercial Spaces

Our process starts with a detailed site assessment and engineered calculations: outdoor air requirements per ASHRAE 62.1, pressure zoning, duct velocities, acoustics, filtration needs, and energy modeling to align with California Title 24 and CALGreen. We design and install Daikin-centric ventilation solutions—Dedicated Outdoor Air Systems (DOAS), ERV/HRV, make-up air units, and VAV distribution—so your building gets the right outside air, at the right conditions, with smart control.

We coordinate closely with ownership, architects, and GCs to phase work around operations, protect finished spaces, and streamline permitting. Our goal is simple: deliver predictable outcomes with clean documentation and commissioning that proves performance.

Daikin Ventilation Solutions We Install

• Dedicated Outdoor Air Systems (DOAS) for precise ventilation and humidity control
• Energy Recovery Ventilators (ERV) and Heat Recovery Ventilators (HRV) to reduce energy use
• Make-up air units for kitchens, labs, and process exhaust balance
• Packaged rooftop units with engineered ventilation strategies
• VAV and pressure-controlled distribution for multi-zone buildings

We integrate Daikin ventilation with building automation (BACnet/Modbus) for demand-controlled ventilation (CO2), scheduling, fault detection, and energy reporting.

Indoor Air Quality and Filtration

• MERV 13+ filtration and HEPA add-ons where needed
• UV-C and advanced purification options upon request
• Humidity management for comfort and material protection
• Source capture and local exhaust for high-load areas

Our mission—healthy air for healthier lives—guides every design choice, from filtration to diffuser placement and sound control.

Compliance, Testing, and Commissioning

We design to ASHRAE 62.1/90.1, California Title 24, CALGreen, and applicable local codes. Our team provides acceptance testing, TAB (Testing, Adjusting, Balancing), and full commissioning with trend logs and punch-list resolution. You receive as-builts, O&M manuals, and training so your facilities team can operate confidently.
