Commercial Warehouse HVAC Systems in Fullerton

Engineered HVAC for Fullerton Warehouses

Warehouses face unique challenges: high ceilings that trap heat, frequent door cycles at loading docks, variable occupancy, and products that demand stable temperature and humidity. Our engineering team designs commercial warehouse HVAC systems that mitigate stratification, reduce infiltration at dock doors, and maintain even conditions from floor to ceiling. We size equipment using precise load calculations, integrate destratification strategies, and specify ventilation that meets code while minimizing energy spend.

AC PRO‑Supplied Reliability

To keep projects moving, we source equipment, controls, duct systems, and OEM parts through AC PRO. This supply chain strength helps us secure fast availability, consistent quality, and predictable costs for Fullerton builds and retrofits. Whether you need high‑efficiency rooftop units, heat pumps, ventilation packages, or filtration media, our AC PRO sourcing streamlines delivery and supports warranty integrity.

Factory Training That Matters

Our technicians are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea, Gree, and Haier (China). That training translates into correct selection, commissioning, and service of advanced technologies—VRF/mini‑split systems, heat pumps, and dedicated ventilation—so your warehouse gets dependable performance, smart controls, and lower lifecycle costs.

Healthy Air, Productive People

Healthy air is our mission. We design ventilation and filtration that support worker comfort and help protect sensitive inventory. From MERV‑13+ filtration to demand‑controlled ventilation and humidity management, we balance indoor air quality with energy efficiency so your operations stay compliant and your teams feel better on the floor.

• Right‑sized outside air and make‑up air for code compliance
• MERV‑rated filtration strategies tailored to dust and process loads
• Humidity control to protect packaging, electronics, and perishables
• Airflow zoning to stabilize temperatures across aisles and mezzanines

Energy and Controls Optimization

Energy is a major line item for warehouses. We employ control sequences that trim peak demand and stabilize conditions: economizers for cool‑air free cooling, demand control ventilation to modulate outside air, variable frequency drives for supply and exhaust fans, and smart scheduling to align with shift patterns. These measures improve comfort while reducing operating costs.
