Maintenance, monitoring, and repair for air-cooled standby generators across Southeast Michigan — no matter who installed it.
Scheduled inspections, oil and filter service, and battery and transfer switch testing that keep your unit ready before the power ever goes out.
If your standby generator failed to start during an outage, tripped a fault code, or isn't running the way it used to, we can help get it back into ready status.
Our plans are built around what your generator actually needs — inspection, battery and transfer switch testing, remote monitoring at a affordable price.
We show up when we say we will, for scheduled maintenance and urgent calls alike, because a generator problem doesn't wait — and neither should we.
Every technician is trained across a variety of systems, so your unit is serviced correctly regardless of age or condition.
You'll always see a clear, written quote before any repair begins — no surprise invoices, upsells, or requirements tied to who installed your unit.
From battery handling to transfer switch work, we follow strict safety protocols, protecting your family and your equipment on every single job.
