Commercial Data Center Cooling in Long Beach

As a fourth-generation family business, #1 AC Guys brings 80+ years of engineering discipline to commercial data center cooling in Long Beach. We design and maintain precision environments that protect your servers, storage, and network gear while reducing energy spend. Our mission is healthy, stable air for a healthier business and workforce, achieved through best-practice thermal management and clean-air strategies.

What we deliver in Long Beach

• End-to-end solutions: assessment, design-build, installation, commissioning, and life-cycle maintenance
• Retrofits in live data halls with zero unplanned downtime and documented MOPs
• Redundancy planning: N, N+1, and 2N architectures aligned to your SLA and risk profile
• Integration with BMS/DCIM and networked sensors for alarms, trends, and capacity planning
• Rapid parts and equipment availability through AC PRO to keep timelines tight

Every project starts with detailed load calculations and airflow strategy. We evaluate cabinet densities, hot spots, cable management, and future growth so your cooling plant scales without waste. Then we commission thoroughly to prove performance under failover and peak conditions.

Technical capabilities

• Precision cooling topologies: CRAC/CRAH, in-row and overhead units, rear-door heat exchangers
• DX and chilled-water systems, including free-cooling and waterside/airside economizers
• Containment: hot-aisle and cold-aisle strategies with CFD-informed layouts
• Controls and optimization: VFDs, EC fans, dew point control, supply air reset, adaptive setpoints
• Humidity management: humidification and dehumidification per ASHRAE TC9.9 envelopes
• Leak detection, condensate management, and alarm escalation to prevent water-related incidents
• Filtration strategies for adjacent spaces and support rooms to promote cleaner, healthier air
• Peripheral space conditioning: UPS, battery rooms, network closets, and NOCs

We apply California Title 24 energy standards, local Long Beach permitting, and seismic anchorage best practices. Coastal conditions demand corrosion-aware design; we specify coatings, materials, and maintenance intervals to withstand marine air while preserving capacity and efficiency.

Design and compliance

Our engineers follow ASHRAE TC9.9 thermal guidelines and coordinate with your electrical, fire, and IT teams for a clean handoff. Documentation includes submittals, shop drawings, startup checklists, and O&M manuals. We verify airflow balance, seal penetrations, validate containment integrity, and test failover sequences with your operations staff present.

We are factory-trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That manufacturer-level knowledge helps us configure advanced controls, stage compressors and pumps correctly, and calibrate sensors for stable, efficient operation. For fast local logistics, we source equipment and parts through AC PRO to compress lead times and reduce risk.

Maintenance and 24/7 support

• Proactive PM: coil cleaning, firmware updates, sensor calibration, refrigerant health checks
• Thermal analytics: trend review, hotspot mitigation, and capacity optimization
• Critical spares programs and on-site kits aligned to your SLA
• Emergency response 24/7 with clear escalation paths and communication
• Air quality improvements for adjacent occupied zones to support a healthy workplace

Our clean-room style service habits reduce dust ingress and protect sensitive gear. We schedule maintenance windows, provide MOP/SOP/EOP documentation, and coordinate with facilities and IT for safe execution.
When issues arise, our on-call team responds rapidly across Long Beach, the South Bay, and greater Los Angeles County, including nearby Orange County, Ventura County, and Western Riverside County.
