Precision cooling — chillers, CRACs, and chilled-water plants.
Pay range
$55,000 – $85,000
Entry path
HVAC certification (1–2 year program) + EPA 608
About the role
Data center cooling is its own discipline. CRAC and CRAH units, hot/cold aisle containment, chilled-water plants, and increasingly liquid cooling for AI-class GPU racks all need specialists. The HVAC apprenticeship pathway is shorter than electrical — most people can be operationally productive within 18 months — which makes this the fastest credentialed entry into well-paid data center work.

- •Maintain CRAC/CRAH units and chilled-water systems
- •Tune airflow and containment for hot/cold aisle balance
- •Service chillers, pumps, cooling towers, and dry coolers
- •Diagnose temperature and humidity excursions across the data hall
- •Commission new cooling infrastructure on expansion projects

- •Manufacturer training on Liebert, Stulz, Schneider, Trane equipment
- •OSHA 10 or 30
Best fit for
- •HVAC graduates choosing where to specialize
- •Refrigeration techs from grocery or industrial cold storage
- •Faster entry path than electrical for people without trade-school history
A typical day
Check overnight alarm history at shift start. Walk the chilled-water plant — pumps, towers, valves. Replace a failed humidifier panel in one CRAC unit. Eat lunch. Afternoon ticket: a hot spot in row 14 — investigate airflow, adjust containment, recheck temperatures. Close out tickets before handoff.
