Generator Maintenance & Repair in Colorado
A standby generator only counts if it starts. Hunter Electric is a listed Cummins technician — scheduled maintenance, diagnostics, repairs, and warranty service that keep your backup power ready.
Maintenance Now Beats a Dead Generator Later
Standby generators sit idle for months, then have to start in a snowstorm. That’s exactly why Cummins publishes a maintenance schedule — and why we offer recurring service plans that follow it, so your system exercises, tests, and starts when it matters. We service standby generators across the Denver metro and along the Front Range.
- Scheduled maintenance plans on the Cummins service schedule
- Diagnostics for fault codes & failed exercise cycles
- Repairs by a listed Cummins technician
- Cummins warranty service on covered equipment

Generator Service Questions
How often should a standby generator be serviced?
Follow the Cummins maintenance schedule for your model and usage — typically at least annual service, plus the unit’s own weekly self-exercise. We can put you on a recurring plan so it’s never forgotten.
My generator failed its exercise cycle — what now?
Don’t wait for the next outage to find out why. Call us with the fault code if one is displayed; we’ll diagnose the cause — battery, fuel, controller, or transfer switch — and fix it properly.
Do you service generators you didn't install?
Yes — we provide maintenance, diagnostics, and repairs for Cummins generators regardless of who installed them, and as a listed Cummins technician we can perform warranty service on covered equipment.
