Commercial Warehouse HVAC Systems in Fullerton

Why #1 AC Guys for Warehouse HVAC in Fullerton

Warehouses challenge HVAC systems with large volumes, variable occupancy, dock infiltration, and mixed-use zones. #1 AC Guys meets those challenges with an engineering-first approach grounded in four generations of expertise and 80+ years in engineering. Our team has trained at the factories of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China), applying advanced manufacturer methodologies to real-world warehouse conditions in Fullerton and across Orange County.

Our mission is healthy air for a healthy life—and that extends to every worker and every aisle in your facility. We focus on clean ventilation, stable temperatures, and smart energy use so your operation runs smoothly, safely, and efficiently.

Comprehensive Commercial Services

• Design/Build HVAC for New Warehouses: Load calculations, airflow mapping, duct and diffuser layout, equipment selection, controls, and commissioning.
• Retrofits & Upgrades: Replace aging rooftop units, convert to high-efficiency heat pumps or VRF, add DOAS/ERV for code-compliant ventilation, and integrate modern controls.
• Ventilation & IAQ: Make-up air units, dedicated outdoor air systems (DOAS), energy recovery ventilators (ERV), economizers, MERV-rated filtration, and demand-control ventilation.
• Zoning & Controls: Intelligent zoning for high-bay storage, picking lines, dock doors, and office mezzanines; BACnet-compatible controls and remote monitoring.
• Temperature & Humidity Management: Precision strategies to protect sensitive inventory and equipment, mitigate stratification, and control condensation.
• Maintenance & Reliability: Proactive plans tailored to duty cycles—filters, belts, coil cleaning, sensor calibration, refrigerant checks, economizer tuning, and performance reporting.

Systems We Engineer, Install, and Service

• High-efficiency rooftop packaged units (gas/electric or heat pump)
• VRF/VRV heat pump and heat recovery systems (great for zone diversity)
• Split systems and ducted solutions for offices and ancillary spaces
• Dedicated outdoor air (DOAS) and make-up air with energy recovery
• Economizers, ERV/HRV, and demand-controlled ventilation strategies
• Destratification and airflow optimization to reduce hot/cold spots

Whether you run a logistics hub near the 91/57, an e‑commerce fulfillment center, or a manufacturing warehouse, we tailor capacity, duct design, and ventilation for your square footage, ceiling height, and process loads.

Built for California Codes and Real-World Use

We design with California Title 24, ASHRAE 62.1 ventilation guidelines, and practical serviceability in mind. That means correctly sized outside air, economizer logic that actually performs, accessible filters and coils, and controls that your team can understand. Our goal: fewer surprises, lower total cost of ownership, and safer, healthier air.

Our Fullerton Project Process

• Assessment: Site walk, interviews, and review of utility data and floor plans.
• Engineering: Load calculations, ventilation modeling, and airflow balancing strategy.
• Solution Options: Side‑by‑side options for first cost, energy usage, and maintenance.
• Permitting & Coordination: We coordinate with the City of Fullerton and relevant agencies for a smooth path to approval.
• Installation: Safety-driven installation with minimal disruption to operations.
