Commercial Warehouse HVAC Systems in Ontario, CA

Design‑Build Expertise for Large Warehouses in Ontario, CA

Warehouses aren’t just big boxes—they are dynamic environments with fluctuating heat loads, constant material movement, and varying headcounts. Our engineers design Commercial Warehouse HVAC Systems that account for stratification in high bays, airflow losses at loading docks, and ventilation needs across pick lines and mezzanines. We model loads, right‑size equipment, and coordinate distribution strategies that keep temperatures even from floor to ceiling while controlling energy spend.

Whether you need a ground‑up design or a retrofit that minimizes downtime, we coordinate closely with your GC, racking provider, fire/life safety, and electrical contractors to sequence work safely and efficiently.

Why We Specify AC PRO for Warehouses

AC PRO offers robust commercial solutions supported by strong local inventory—critical for fast installs and rapid service. We integrate AC PRO rooftop units, split systems, ductless solutions, and ventilation components to match your layout and budget while ensuring long‑term serviceability.

• Rooftop units optimized for high‑bay environments
• Economizer options for free cooling when Ontario’s conditions allow
• Compatible with advanced controls and BMS platforms
• Reliable parts availability to reduce downtime
• Flexible configurations for phased growth and tenant improvements

Indoor Air Quality, Ventilation, and Code Compliance

Healthy air supports safer, more productive facilities. We design ventilation to ASHRAE 62.1 guidelines and align systems with California Title 24 requirements. From dedicated outdoor air systems to filtration upgrades and supply/return layouts that address dust and process heat, our goal is a clean, balanced environment that meets code and supports your operations.

Our mission is healthy air for healthy life—and that principle guides every warehouse we build, retrofit, or service.

Energy Efficiency and Smart Controls

We prioritize payback and performance without sacrificing comfort or air quality.

• Variable frequency drives for supply/return fans
• Demand control ventilation with CO2 sensing
• Economizers for free cooling during favorable conditions
• Zoning strategies for active and low‑use areas
• Setback and scheduling for shifts, weekends, and holidays
• Smart thermostats and BMS integration for portfolio oversight
• Air distribution tuned to minimize stratification and hot spots

These tools help reduce utility costs and smooth operations—especially valuable for Ontario facilities with long hours and seasonal swings.
