Commercial Data Center Cooling in Fullerton, CA

Engineer‑Led Precision for Mission‑Critical Cooling

Data centers in Fullerton demand predictable thermal performance, rock‑solid redundancy, and efficient operation. As a 4th‑generation family of engineers with 80+ years in engineering, #1 AC Guys brings deep technical rigor to commercial data center cooling. Our factory‑trained team at Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China) delivers solutions that align with ASHRAE TC9.9 thermal guidelines, local codes, and California Title 24 energy requirements.

What We Do

• Design‑Build and Engineering: Load analysis, CFD‑informed airflow strategy, equipment selection, and phased implementation that minimizes risk and downtime.
• CRAC/CRAH Systems: Precision temperature and humidity control tailored to rack density, diversity, and growth plans.
• Airflow & Containment: Hot‑aisle/cold‑aisle containment, blanking panels, brush grommets, and raised floor tuning to eliminate bypass and hotspots.
• Redundancy & Resilience: N, N+1, and N+N architectures with failover logic and serviceability built in.
• Controls & Integration: BMS/DCIM integration, sensors, alarming, and trend logging to maintain tight setpoints and visibility.
• Retrofits & Upgrades: Capacity adds, economizer strategies, VFD optimization, and controls modernization for efficiency and scalability.
• Commissioning & Maintenance: Functional testing, calibration, and data‑driven PM that protects uptime and extends asset life.

Technologies We Support

• DX and chilled‑water CRAC/CRAH
• Row‑based and rack‑based cooling
• Free cooling/economizer configurations
• Liquid cooling interfaces and heat‑rejection systems
• Filtration and IAQ strategies that protect sensitive IT

Whether you run a core facility or an edge site in Fullerton, we align cooling capacity, distribution, and control to your IT roadmap—so thermal strategy scales with compute.

Compliance, Safety, and Clean Air

We design for code compliance and safety from day one. Our approach supports California Title 24 efficiency standards and follows industry best practices for electrical clearances, condensate management, leak detection, and equipment service access. Clean, healthy air is central to our mission; we specify filtration and humidity control that protect equipment while contributing to a healthier workplace.

Our Process

• Discovery & Assessment: Site walk, data gathering, load profile, and risk review.
• Engineering & Proposal: Options with lifecycle cost, efficiency, and redundancy trade‑offs.
• Implementation: Sequenced work to avoid disruption, with detailed change management.
• Commissioning: SAT, trending, controls tuning, and documentation.
• Operate & Optimize: Proactive maintenance and continuous improvement via performance data.

We prioritize clear communication, precise documentation, and coordination with IT, facilities, and GC partners to keep projects on time and within budget.
