Precision Cooling Service and Maintenance

We service perimeter CRAC and CRAH units, in-row cooling, chilled-water systems, rear-door heat exchangers, and the chillers, condensers, and CDUs that support them. As a long-standing distribution partner of Vertiv and Schneider Electric and a vendor-agnostic provider, we maintain major brands and mixed fleets across Central Texas under one contract.

Precision cooling is commonly serviced quarterly or semi-annually, with filter changes, coil cleaning, refrigerant and controls checks, condensate management, and setpoint verification. Regular service preserves efficiency and prevents the gradual wear and drift that lead to failures. The right interval depends on the environment and how critical the load is.

A CRAC (computer room air conditioner) uses a refrigerant-based direct-expansion system with a compressor, while a CRAH (computer room air handler) uses chilled water supplied by a central plant. CRAHs are common in larger facilities with a chilled-water loop, while CRACs suit smaller or standalone spaces. We service and maintain both.

Yes. Comp-Utility provides 24/7 emergency response for cooling failures across Central Texas, with rapid on-site dispatch from Austin. Rising temperatures can damage equipment within minutes, so call (512) 346-0999 immediately. We will guide safe interim steps while we mobilize and then diagnose and restore the failed cooling as fast as the situation allows.

Hot spots usually result from airflow problems rather than insufficient total capacity: missing blanking panels, poor containment, or misplaced perforated tiles. We assess airflow, add containment and blanking, adjust tile and grate placement, and balance the units. Fixing airflow often resolves hot spots and improves efficiency without adding cooling capacity.

Yes. High-density and AI racks can exceed what perimeter air cooling alone can handle. We evaluate your current capacity and design upgrades, from containment and in-row cooling to rear-door heat exchangers and direct-to-chip liquid cooling with CDUs. We plan the transition so cooling scales with your compute growth.

Most data centers target a temperature range in line with ASHRAE recommendations and a controlled humidity band to avoid condensation at the low end and static or corrosion concerns at the extremes. The exact setpoints depend on your equipment and design. We verify and tune setpoints during maintenance to keep your space within the intended envelope.

Yes. Comp-Utility is a turnkey, single-contract partner. We service precision cooling together with UPS, generators, ATS, switchgear, and PDUs, and provide structured cabling and design-build. One Central Texas provider for power and cooling improves coordination during maintenance and emergencies and gives you a single point of accountability.
