Free 24/7 Technical Support
One of our most appreciated services is our free tech support.
Gruber Power Services is committed to keeping your systems online—with guaranteed response times ranging from per call service, to our platinum on-demand service with a 4-hour response time, available 24 hours – 7 days a week – 365 days per year.
We understand the critical impact of downtime in a Data Center environment. When operations are interrupted, there’s no time to waste navigating call queues or waiting for a callback. You need immediate action—and that’s exactly what we deliver.

The moment you call, we assemble a triage team starting with a seasoned Field Engineer who begins remote diagnostics and guides your staff through immediate recovery steps—restart protocols, bypass engagement, breaker resets, and generator hand-offs. Your emergency becomes our top priority.
If replacement parts are needed, our technical support team springs into action—pulling from our extensive in-house inventory and initiating fast-track sourcing for rare components. We keep you informed with real-time updates, ensuring transparency and speed every step of the way.
