Commercial Ventilation Design in Los Angeles

Getting ventilation right in Greater Los Angeles means balancing strict codes, wildfire smoke, heat waves, and diverse building uses—without driving up energy bills or compromising comfort. #1 AC Guys brings deep engineering discipline to Commercial Ventilation Design so your project delivers healthy air, predictable costs, and smooth approvals.

What you get with our commercial ventilation design

• Code‑compliant outside air calculations and airflow schedules aligned with ASHRAE 62.1, Title 24, and CALGreen
• Complete design packages: coordinated plans, sections, details, control sequences, and equipment schedules
• System strategies tailored to use and climate: DOAS, VAV with reheat, ERV/HRV heat recovery, demand‑controlled ventilation, economizers
• Kitchen, restroom, and specialty exhaust with proper make‑up air, capture velocity, and noise control
• Filtration and IAQ strategies for wildfire smoke and urban particulates (MERV 13+ where required)
• Energy modeling inputs and ventilation heat‑recovery options to reduce operating cost
• Constructability reviews for tight plenum spaces, seismic restraints, and phased tenant build‑outs
• Submittal, TAB, and commissioning coordination support for a clean turnover

Our team is trained by manufacturers at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), bringing factory‑level understanding of equipment behavior, controls, and integration that translates into reliable, maintainable ventilation systems on day one.

Engineered for Los Angeles codes and climate

From downtown towers to coastal retail and Valley warehouses, LA’s microclimates demand nuanced ventilation. We design for marine layers, dry heat, and wildfire smoke, applying the right mix of outside air, heat recovery, and filtration. We align with local plan check requirements, Title 24 ventilation metrics, ASHRAE 62.1 minimums, and CALGreen provisions, helping streamline approvals and inspections.

Key design considerations we manage:
- Space type and occupancy diversity across zones
- Outdoor air quality and seasonal smoke incursions
- Peak load vs. part‑load ventilation efficiency
- Sound levels near workstations, classrooms, and guestrooms
- Maintenance access and future flexibility for tenant changes

Project types we serve

• Office campuses, creative spaces, and co‑working floors
• Retail, restaurants, commercial kitchens, and food halls
• Hotels, event venues, and entertainment spaces
• Schools, training centers, and assembly spaces
• Light industrial, production floors, and warehouses
• Healthcare support areas and clinics’ non‑sterile zones
• Multifamily common areas, amenities, and parking ventilation

Large or complex footprint? That’s our specialty. Our fourth‑generation engineering lineage gives us the toolkit to reconcile competing requirements and deliver buildable solutions.

Our process

• Discovery and survey: verify usage, schedules, constraints, and code triggers
• Basis of Design: define IAQ targets, system types (DOAS, VAV, ERV/HRV), control logic, and efficiency goals
• Calculations and modeling: outside air, diversity, pressure, and thermal interactions; CFD where airflow patterns are critical
• Coordination: align with structural, electrical, plumbing, and architectural routing to avoid conflicts
• Documentation: clear drawings, details, and sequences ready for plan check and bids
• Construction support: RFIs, submittal reviews, punch support, and TAB/commissioning coordination

This disciplined workflow reduces redesigns and change orders, keeping your schedule intact.

Healthy air, measured

Air quality isn’t a slogan—it’s measurable. We specify filtration strategies, outside air monitoring, and demand control where appropriate to keep CO2 and particulates in check while trimming energy use. When needed, we integrate heat recovery and smart controls to maintain comfort and IAQ through LA’s wildfire season.

Service area and responsiveness

We serve Los Angeles County and nearby areas, including Orange County, Ventura County, and Western Riverside County. Our engineers are accustomed to local permitting and inspection workflows, delivering responsive support from concept to close‑out.
