Commercial Ventilation System Installation in Ontario, CA

Engineered Ventilation for Ontario’s Commercial Buildings

Healthy air is not a guess—it’s engineered. Our Commercial Ventilation System Installation services in Ontario, CA deliver the right outside air, balanced exhaust, and controlled pressure so your space stays comfortable, compliant, and productive. We design for real‑world loads, occupant patterns, and maintenance realities, then install with clean routing, sealed ductwork, and accessible service points.

What We Install

• Outside air and make‑up air systems sized for code and occupancy
• Energy recovery (ERV/HRV) for efficiency and moisture control
• Exhaust systems: restroom, kitchen, warehouse, lab/process (per application)
• Rooftop ventilators, inline fans, and demand‑controlled ventilation
• Air distribution: AC PRO–supplied ductwork, fittings, diffusers, and grilles
• Filtration upgrades (MERV/HEPA as required), air quality sensors, and controls
• Economizers and control integration with existing HVAC

Our Process

• Assessment: Site survey, airflow targets, code and utility review
• Design: Load calculations, duct layouts, fan curves, and control strategy
• Installation: Clean routing, proper isolation, sealing, and insulation
• Controls: Setpoints, economizer logic, demand control, alarms
• Commissioning: Start‑up, test & balance, and performance verification
• Documentation: Submittals, O&M, and training for your team

We emphasize measurable results—airflow readings, pressure relationships, and verified filtration performance—so you know your system does what the drawings promise.

AC PRO Integration That Lasts

We specify durable AC PRO–supplied duct systems and air distribution products that stand up to commercial use, simplify maintenance, and help control lifecycle costs. From sealed duct classes to properly selected diffusers and registers, every component is chosen to support quiet, even air delivery and long‑term reliability.

Performance & Compliance

We design and install to current codes and industry best practices, documenting outside air rates, exhaust volumes, and pressure control. Our commissioning verifies airflow, setpoints, and energy recovery performance. Expect right‑sized equipment, sealed ducts, and balanced systems that hit performance targets without wasted energy.

Industries We Serve

• Offices, retail, and shopping environments
• Warehouses, fulfillment, and light manufacturing
• Food service and commercial kitchens (make‑up air and exhaust)
• Gyms, wellness, and assembly spaces with variable occupancy
• Healthcare offices and specialized suites (per project requirements)

Retrofits and Expansions

Upgrading an older building in Ontario? We evaluate the existing infrastructure, salvage what makes sense, and retrofit with modern ventilation strategies: ERV/HRV, demand control, improved filtration, and refined air distribution. Our goal is to deliver cleaner air and lower operating costs with minimal disruption.

Controls That Make Sense

We integrate sensible controls—CO2‑based demand ventilation, economizers, scheduling, and alarms—so you get healthy air when you need it and savings when you don’t. Clear labeling and documentation make operations straightforward for your staff.

Service Area

Based in the Greater Los Angeles area, we serve Ontario, CA and neighboring communities across Los Angeles County, Orange County, Ventura County, and Western Riverside County. If your site is near Ontario or along major corridors, we can likely schedule quickly.

Our Mission: Healthy Air for Healthy Lives

Ventilation is the foundation of indoor air quality. By delivering clean outside air, removing contaminants, and balancing pressure, your building supports better health, comfort, and productivity. That’s our mission on every project—engineered, installed, and verified by #1 AC Guys.
