Fontana Commercial Ventilation Design

When clean, code‑compliant air is critical to your business, you need an engineering‑first partner who can take responsibility from concept through commissioning. #1 AC Guys brings 80+ years of engineering expertise and four generations of family know‑how to commercial ventilation design across Fontana and the greater Southern California region.

What we design

• Dedicated outdoor air systems (DOAS) with energy recovery (ERV/HRV)
• Demand control ventilation (DCV) with CO2 sensors for variable occupancy
• MERV 13+ filtration and clean‑air strategies for healthier workplaces
• Economizers and advanced ventilation sequences for Title 24 efficiency
• Kitchen hood exhaust and make‑up air for restaurants and food service
• Warehouse and logistics ventilation with high‑bay destratification
• Laboratory, maker‑space, and specialty exhaust (where applicable)
• Garage ventilation with CO/NO2 monitoring and control
• Negative/positive pressure zoning for healthcare and sensitive areas

Every design is tailored to your building’s use, envelope, and utility profile to deliver predictable comfort and safe indoor air quality at the lowest practical lifecycle cost.

Our engineering‑first process

• Discovery and goals: occupancy, processes, contaminants, schedules, and budget
• Load and airflow calculations aligned with ASHRAE 62.1/55 and IMC
• System selection: DOAS, ERV/HRV, DCV, economizer strategies, and controls
• BIM coordination and clash avoidance with architects and GCs
• CFD‑informed airflow planning for large or complex spaces
• Permit‑ready drawings, equipment schedules, and submittal packages
• Commissioning plans, TAB coordination, and verification checklists
• Owner training and ongoing optimization for sustained performance

We specify AC PRO–ready components to keep procurement smooth and timelines predictable, helping your project avoid delays and change‑order surprises.

Codes, standards, and documentation

Our Fontana ventilation designs are built around ASHRAE 62.1/55, the International Mechanical Code (IMC), California Title 24, and CALGreen. We coordinate fire‑life safety requirements, smoke control interfaces, and applicable NFPA provisions, and assemble permit‑ready documentation that streamlines plan check. Expect clear narratives, sequences of operation, and commissioning checklists your facilities team will actually use.
