Commercial Ventilation Design in Fullerton, CA

Healthy air for healthy living is more than a motto—it is our engineering standard. In Fullerton, we design commercial ventilation systems that deliver the right outdoor air to the right zones at the right times, cutting energy waste while elevating comfort, safety, and productivity. Our approach blends deep field experience with modern tools to ensure your system performs on day one and year ten.

Design-first engineering for healthy, code-compliant air

We begin with a detailed survey: occupancy types, process loads, pollutant sources, hours of operation, local climate, and noise criteria. We calculate ventilation per ASHRAE 62.1, align with California Title 24 and CalGreen, and coordinate with IMC and local ordinances. We then translate requirements into duct routing, pressure profiles, filtration strategy (MERV/HEPA where required), and controls sequences that balance IAQ with energy and acoustics.

Key outcomes include balanced supply/exhaust, proper make-up air for hoods and exhaust systems, odor and fume control, condensation mitigation, and provisions for maintenance access and future scalability—critical for growing Fullerton businesses.

Systems we design and integrate

• DOAS (Dedicated Outdoor Air Systems) for decoupled ventilation and superior humidity control
• ERV/HRV for energy recovery to reduce heating and cooling loads
• Make-Up Air units matched to kitchen, restroom, and process exhaust
• Demand-Controlled Ventilation with CO2/VOC sensing for part-load savings
• VAV/VVT distribution, VFDs, and EC fan arrays for precise airflow and efficiency
• Commercial kitchen ventilation per applicable codes, with hood capture, grease exhaust, and make-up air balancing
• Warehouse and light manufacturing ventilation, including spot/exhaust capture and general dilution
• Garage and enclosed parking ventilation with CO/NO2 monitoring
• Healthcare clinics, dental, and procedure rooms with pressure zoning and filtration strategies
• Laboratory and specialty exhaust integration coordinated with safety requirements

Advanced modeling, coordination, and commissioning

Where projects warrant, we apply airflow analysis and digital coordination to reduce risk before construction. We review duct friction, fittings, and fan curves to ensure stable operation across all modes. Our team coordinates in BIM environments to prevent clashes and to preserve ceiling heights and service clearances.

Commissioning and testing are planned from day one: we specify TAB procedures, setpoints, sensor locations, and acceptance criteria so the installed system achieves the design intent. Clear sequences of operation enable stable control, better diagnostics, and lower lifecycle costs.

Energy, sustainability, and occupant experience

Energy efficiency is embedded in our designs through recovery wheels/cores, economizer logic, high-efficiency filtration with minimal pressure penalties, VFD fan turndown, and intelligent demand control. By stabilizing temperature, humidity, and ventilation rates, we improve comfort, reduce complaints, and help protect finishes and equipment.

We design for maintenance too—filter access, coil cleaning, and service clearances—because systems that are easier to maintain stay efficient longer.
