Mission-Critical Cooling Services
Precision cooling isn't comfort HVAC. Tight temperature and humidity tolerances, redundancy, and uptime keep your equipment alive — that's what we do.
CRAC / CRAH Service & Repair
Diagnostics, repair, and preventive maintenance for computer room air conditioners and air handlers — compressors, humidifiers, controls, airflow.
Emergency Cooling Response
Cooling failure in a live server room? Mission-critical calls get priority dispatch plus temporary spot-cooling to keep you online while we repair.
Preventive Maintenance Contracts
Scheduled inspections, filter and refrigerant checks, condensate management, and airflow verification — catching failures before downtime.
Dedicated Server Room AC
Installation and service of mini-splits and dedicated cooling for server rooms, IDF/MDF closets, and network rooms — sized for real IT heat loads.
Cooling Assessments & Monitoring
Heat load calculations, hot/cold aisle review, temperature monitoring setup, and honest recommendations before problems become outages.
Subcontracting for HVAC & MSPs
Licensed local C-20 subcontractor for after-hours coverage, overflow work, and emergency response on behalf of larger contractors and IT providers.
We Understand Airflow
Hot/cold aisle containment, raised-floor supply, return plenums — server room cooling is about managing airflow, not just adding tonnage.
- Hot/cold aisle analysis — we find recirculation and bypass air that wastes capacity.
- Right-sized equipment — no oversold tonnage, no short-cycling units.
- Manufacturer guidelines — service per Vertiv, STULZ, and ASHRAE datacom standards.
Cold aisle supply / hot aisle return — the airflow pattern we optimize.
Modern facilities increasingly rely on liquid cooling loops and CDUs.
From Mini-Splits to Chilled Water
We service the full range of critical cooling infrastructure found in San Diego facilities:
- DX systems — dedicated splits and packaged CRAC units.
- Chilled water systems — CRAH units, pumps, and loop maintenance.
- Glycol & condenser loops — dry coolers and fluid coolers.
- Humidity control — humidifiers, reheat, and dew point management.
How Data Center Cooling Works
From cooling tower to the rack — we service every stage of the heat rejection chain.

Condenser Water System → Chiller → Facility Water System → CDU → Technology Cooling System → IT racks.
