Commercial Ventilation Design in Long Beach

When ventilation is engineered right, your building breathes effortlessly: fresh air is delivered where and when it’s needed, contaminants are exhausted, and energy use stays under control. At #1 AC Guys, our mission is healthy air for a healthy life—applied to the workplace with rigorous engineering. In Long Beach, that means designs that handle coastal air, salt corrosion, mixed-use occupancy, and tight energy codes without compromising indoor air quality.

What makes our Long Beach ventilation design different

• Fourth-generation family of engineers with 80+ years of cumulative engineering experience.
• Focus on complex commercial projects: multi-tenant, food service, healthcare suites, distribution, and specialized spaces.
• Compliance-first approach: ASHRAE 62.1 and 55, California Title 24, CALGreen, and local municipal requirements.
• Factory-trained at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China) for precise integration and control strategies.
• BIM coordination to prevent clashes, reduce change orders, and accelerate construction.
• TAB and commissioning support to verify airflow, pressure balance, and controls performance.

Our commercial ventilation design process

• Discovery and site walk: occupancy, process loads, schedules, constraints, and future growth.
• Engineering calculations: ventilation rates per ASHRAE 62.1, diversity factors, stack effect, and pressure zoning.
• System selection: dedicated outdoor air systems, ERVs/HRVs, economizers, fans, filtration, and controls.
• Duct and equipment layout: optimized runs, velocity control for noise, fire-smoke damper placement, and access for service.
• Controls strategy: demand-controlled ventilation, CO2 sensing, scheduling, and integration with BAS.
• Permit-ready package: plans, details, equipment schedules, and Title 24 documentation to speed approvals.
• Construction support: responses to RFIs, submittal reviews, and field visits.
• Testing, adjusting, and balancing guidance to deliver specified airflow and comfort.

Health-first indoor air quality

Our designs prioritize people. We specify ventilation rates and air distribution patterns that dilute pollutants, manage humidity, and maintain consistent comfort across zones. For high-risk areas or sensitive operations, we can design isolation, negative or positive pressure regimes, and enhanced filtration to address particulate, odor, and aerosol control.

• Right-size outdoor air with proper mixing and distribution for uniform CO2 levels.
• Filtration strategies using appropriate MERV ratings or specialty filters where required.
• Humidity management to reduce mold risk and protect finishes and equipment.
• Optional technologies such as UV-C in appropriate applications, integrated without compromising safety or code.

Energy efficiency and code compliance

Ventilation should be efficient and compliant from day one. We align designs with Title 24, prepare documentation, and identify measures that often pay for themselves.

• Energy and heat recovery ventilators to reclaim exhaust energy.
• Economizers and outdoor air reset strategies for mild coastal conditions.
• Demand-controlled ventilation based on occupancy and CO2 sensors.
• High-efficiency fans and VFDs for turndown and quiet operation.
• Envelope and stack-effect considerations to stabilize pressure and reduce drift.

Industries we serve in Long Beach

• Offices, co-working, and creative spaces
• Retail, grocery, and shopping centers
• Restaurants, commercial kitchens, and food prep with makeup air
• Warehouses, distribution, and light industrial
• Healthcare clinics, dental, and procedure suites
• Labs, R&D, and specialty rooms with pressure zoning
• Fitness studios and assembly spaces
• Multifamily common areas and parking exhaust

Coastal and seismic design considerations

Long Beach presents unique demands: marine air, salt exposure, and seismic requirements. We select corrosion-resistant materials, specify coatings and fasteners suited for coastal environments, and design seismic bracing per California Building Code. The result is a system that resists the elements and performs reliably through its life cycle.

Deliverables that keep projects moving

• Permit-ready mechanical plans, details, and equipment schedules.
• Ventilation narratives with basis of design and sequence of operations.
• Title 24 compliance documentation and coordination notes.
• BIM models for coordination and clash detection.
• TAB, commissioning checklists, and O&M guidance.

We coordinate closely with owners, developers, architects, GCs, and subs to keep submittals and RFIs on track. Our goal is fewer surprises in the field and quicker sign-offs from inspectors.

Local focus with regional reach

We serve all of Long Beach—Downtown, East Village, Belmont Shore, Naples, Bixby Knolls, Wrigley, and the Port of Long Beach—plus Signal Hill and surrounding communities. Our wider service area includes Los Angeles County, Orange County, Ventura County, and Western Riverside County, so your multi-location portfolio can work with one engineering partner.
