Liebert (Vertiv) CRAC and precision cooling service in San Diego County

Liebert (Vertiv) precision cooling we work on

Liebert, now part of Vertiv, has one of the largest installed bases of CRAC units, CRAH units and in-row precision cooling in US server rooms and data centers. We work on perimeter CRAC and CRAH units, in-row coolers, and the condensers, dry coolers, humidifiers and controls that go with them.

Installation and replacement

We help size and plan new or replacement Liebert (Vertiv) units around your room's heat load, airflow path, power and condenser location, then handle the install, refrigerant work, startup and documentation. When a room is growing, we'll talk through whether added in-row capacity or a perimeter unit makes more sense.

Repair and service

On a service call we check alarms and controller history, refrigerant circuits, compressors, fans, humidifiers, condensate pumps and the outdoor condenser or dry cooler, and we explain what failed before any repair starts. Office hours are Monday–Friday, 8 am–5 pm. After hours, our answering service takes your message and our office follows up the next business day, so redundancy matters. We're glad to help you plan for it.

Planned maintenance

Scheduled maintenance keeps precision cooling reliable. That means filters, belts, coils, humidifier canisters, condensate lines, refrigerant checks and controller settings, all on a schedule that fits your site. See commercial HVAC and maintenance plans.
