Diagnosed properly, not guessed at
Controllers, transfer switches and fault codes differ from brand to brand, which is why factory training matters on a repair call. Our Generac and Kohler certified technicians check the engine, alternator, controller, transfer switch and fuel system in sequence, then fix the cause instead of clearing the code. If a unit has reached the end of its life, we say so and walk you through a new generator installation so you can weigh repair and replacement side by side.
What a Roland Black generator repair includes
- 01
A person answers, day or night
Nights, weekends and active storms included, with bilingual staff on the line to get a technician moving.
- 02
Same-day service in most cases
A factory-trained technician arrives in a truck stocked with batteries, filters, sensors and other common generator parts.
- 03
A full diagnostic before any part
Engine, alternator, controller, transfer switch and fuel system are tested in order, so nothing is replaced on a hunch.
- 04
A written quote before work starts
You see the repair, the parts and the financing options in writing, and nothing proceeds until you approve it.
- 05
A test run under load
Once the fix is in, we run the generator under load and confirm the transfer switch hands power back and forth cleanly.
Why homeowners pick us for generator repair
Factory-deep brand knowledge
Generac and Kohler certification means our technicians read fault codes the way the manufacturer intended.
On call through the storm
Our dispatch line runs 24/7, which matters most on the nights the grid is already down.
Stocked trucks, fewer return trips
Common wear parts ride on the truck, so most repairs are finished on the first visit.
Straight answers on repair or replace
When a unit is past saving, we tell you and show you why instead of selling repair after repair.
Generator problems we fix most often
Standby units sit idle for months, then get asked to carry a whole house. They tend to fail in a few predictable ways.
It will not start when the power drops
Usually a weak battery, a fuel system that has lost prime, a tripped low oil pressure sensor or an uncleared controller fault. We check each one in turn.
It failed its weekly self-test
A failed exercise cycle is the unit warning you before the next outage does. Battery age, fluid levels and ignition faults are the usual suspects.
It runs but will not carry the house
When the transfer switch or controller misbehaves, the engine runs while the house stays dark. We trace the fault through the whole transfer path.
Most repairs finish on the first visit
Our vans leave E Franklin Blvd stocked with the parts standby generators wear through most, so you are not left waiting on a shipment while the next storm lines up.

Generator Repair questions, answered
Yes. We service Generac, Kohler and other major brands no matter who installed them, and every unit gets the same full diagnostic.
Our dispatch line is answered 24/7, including during active storms. Arrival times depend on road conditions and how many calls are open, and we keep you updated while we are on the way.
That usually points to the automatic transfer switch or the controller rather than the engine. We test the full transfer path so the unit both runs and delivers power to your panel.
Often it is, especially when the engine is sound and the fault sits in the battery, a sensor or the controller. If parts are no longer available or repairs keep stacking up, we lay out replacement as an option with the trade-offs in writing.
