Commercial Ventilation Design in Anaheim

When indoor air quality, comfort, and compliance matter, #1 AC Guys delivers commercial ventilation design that fits your building’s purpose and your budget. We specialize in complex projects and mission‑critical spaces where performance cannot be left to chance.

What we design

• Outdoor air systems (DOAS) with ERV/HRV for energy‑smart fresh air
• High‑efficiency filtration strategies (MERV‑13 to HEPA) and cleaner-air pathways
• Demand Control Ventilation (CO₂/VOC sensors) and smart economizers
• Make‑up air and exhaust systems for kitchens, labs, and process spaces
• Warehouse and manufacturing ventilation, destratification, and relief
• Smoke control considerations, pressurization, and stairwell ventilation
• Acoustic treatment and diffuser selection for quiet, even air distribution
• BIM/CAD duct layouts coordinated for clash‑free installation

Our engineers are factory‑trained at Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That real‑world product knowledge helps us match equipment to your application for reliability, serviceability, and lifecycle value.

Our process

Discover
We start with a site walk, drawings review, and stakeholder goals. We document occupancy types, process loads, code triggers, and existing constraints.

Design
We perform airflow and ventilation rate calculations per ASHRAE 62.1 and Title 24, size ductwork and exhaust, specify filtration, and model control sequences (e.g., DCV, night purge, economizer). CFD airflow visualization is available on request for sensitive areas.

Document
We deliver coordinated plans, details, and schedules in CAD/BIM, plus equipment selections and sequences of operation. Submittal packages are plan‑check‑ready.

Deliver & Support
We assist through permitting, contractor RFIs, value engineering, and field coordination. TAB and commissioning support help your system perform as designed.

Health and IAQ first

Healthy air is our mission. We design with proper outdoor air, filtration, dilution, and control logic to reduce contaminants while maintaining comfort. Options include upgraded MERV‑13+ filters, HEPA where applicable, UV‑C in select use‑cases, and real‑time IAQ sensing tied to ventilation demand.

Codes and standards we follow

• ASHRAE 62.1 for ventilation, and 55 for thermal comfort
• California Title 24 energy code and CALGreen requirements
• IMC/CMC mechanical code; NFPA 96 for commercial kitchen ventilation
• Local plan‑check practices in Anaheim and Orange County jurisdictions

Our drawings and calculations reflect the latest code requirements and local amendments to streamline approvals and construction.

Industries we serve

• Office, retail, mixed‑use, and tenant improvements
• Restaurants, commercial kitchens, and food production
• Warehouses, distribution, light manufacturing
• Healthcare offices, clinics, and wellness spaces
• Schools, labs, and R&D environments
• Hospitality, entertainment, and assembly spaces

What you get

• Clear basis‑of‑design and ventilation calculations
• Duct and diffuser layouts, risers, details, and equipment schedules
• Control sequences (DCV, economizer, purge, setbacks)
• Specifications aligned with performance and maintenance goals
• Coordination with architectural, structural, plumbing, and electrical
• Responsive support through plan check and construction
