Commercial Warehouse HVAC Systems in Orange, CA — AC PRO Solutions

Why warehouses in Orange choose #1 AC Guys

Large, open volumes and frequent dock activity make warehouses some of the most challenging commercial environments. Our engineering‑first approach stabilizes temperatures, improves indoor air quality, and reduces energy use while meeting code. Expect consistent comfort in picking lines and offices, better protection for sensitive inventory, and systems designed for uptime and serviceability.

We are a family business in its 4th generation with 80+ years of engineering experience. Our commercial team thrives on complex, multi‑zone projects and fast‑track retrofits across the City of Orange and surrounding Orange County.

AC PRO equipment access and advantages

We source equipment and critical parts through AC PRO to keep timelines tight and support readily available. That means rapid replacement options for rooftop packaged units, economizers, make‑up air systems, air handlers, VFDs, thermostats, and filtration. With dependable supply chains, your project avoids costly delays—and your maintenance plan stays on schedule.

For specialized zones (offices, QC labs, server rooms), our team integrates high‑efficiency ductless and VRF solutions backed by our factory training with Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). The result is a unified, controllable system tailored to the way your warehouse operates.

Design‑build process that fits your operation

• Facility assessment: heat loads, infiltration at dock doors, racking height, occupancy patterns, and equipment heat.
• Right‑sizing: detailed load calculations to avoid oversizing and short cycling.
• Airflow strategy: supply/return placement, destratification, and zoning for offices/mezzanines.
• Equipment selection: AC PRO‑sourced packaged rooftops, make‑up air units, and energy‑saving economizers.
• Controls and monitoring: smart thermostats, scheduling, CO2 monitoring, and alarm notifications.
• Commissioning and documentation: balancing, verification, and O&M packages for your team.

Every step aligns with California Title 24, local permitting, and best practices for safety and maintainability.

Healthy air is our mission

We believe healthy air powers healthy lives. For warehouses, that means proper ventilation rates, quality filtration, and pressure management that mitigates dust and outdoor intrusion at busy docks. We implement MERV‑rated filters, optional HEPA for sensitive areas, and make‑up air strategies that reduce negative pressure. Where beneficial, we incorporate economizers for free cooling and add CO2 sensors to validate ventilation in office build‑outs.
