Upkeep on city or Duke power
Preventive Generator Maintenance in Concord, NC
Concord Electric Systems serves some homes here and Duke Energy serves others, but a standby unit on either grid needs the same care: fresh oil, a strong battery and a switch that transfers. We service home generators across Concord, ahead of 88°F summer highs and winter lows near 29°F.

What a Concord unit gets at each service
Each visit ends with a plain verdict on the unit: serviced and ready, or in need of a part. When it is the second, we price the generator repair in Concord on paper first, and nothing is replaced until you approve it.
Ready for a 29°F start
A battery load test before winter catches a weak cell ahead of a 29°F morning, when cold saps cranking power and the unit has to start unattended.
A hand-off with the house on it
We put the transfer switch through a real hand-off with house circuits connected, which an exercise run without load does not test.
Ahead of Hugo's season
A pre-season visit puts the unit in shape before hurricane season peaks, the season that sent Hurricane Hugo's winds into Cabarrus County in September 1989.
Records for a warranty claim
Dated service records from a Generac and Kohler certified tech show the maintenance the manufacturer expects, which helps if a warranty claim on your unit ever comes up.
Clear intake, intact wiring
We clear leaves, grass clippings and rodent nests from inside the enclosure and around the intake, so nothing blocks cooling airflow or chews through wiring between visits.
Controller faults caught early
Controller and firmware checks catch logged faults, wrong exercise settings or a lost Wi-Fi monitoring link before the unit is asked to carry the house.
How Roland Black handles a Concord service call
Two brands, two service manuals
Our technicians are certified installers for Generac and Kohler, and they follow the service schedule and parts list each maker publishes for the exact engine in your yard.
Breakers and lugs checked too
Licensed electricians (license #34773) check the transfer switch, breakers and lug connections on the same visit, so a loose lug is caught on the same trip as a dirty air filter.
Spring and fall, if you want both
Owners can book one visit before summer storms and a second before winter, so oil, plugs and battery are fresh before heat and cold put the hardest demands on the engine.
One team from tune-up to repair
If a visit finds a failing part, the same certified techs quote the fix, and the 10-year Roland Black warranty applies to that work. Larger repairs can be financed.
Open 24/7 through a Cabarrus outage
If your generator logs a fault while Cabarrus is dark, the line at our Gastonia shop is open 24/7.
Generator upkeep questions from Concord owners
The county, not the city. Cabarrus County Construction Standards inspects building and electrical work countywide, Concord included. Changing oil, plugs or a battery is upkeep on the unit itself. Should a visit show that a failing transfer switch or damaged wiring has to be replaced, that becomes permitted electrical work, and we handle the Cabarrus filing and the county inspection.
For a unit that mostly runs its weekly exercise, usually yes, and Generac publishes yearly maintenance guidance for home standby units. A long outage changes that, because the oil interval is set in run hours and shortens when the engine works in heat above 85°F. Concord summers average 88°F, so after a multi-day summer outage we change the oil rather than wait for the annual date.
Because ice does as much harm here as wind. The December 14 to 16, 2005 ice storm cut power to 328,000 North Carolina customers, and Cabarrus was among the counties where it took lives. A fall visit tests the battery for cold starts near 29°F, changes oil that summer running wore down and clears leaves from the intake before the unit sits idle for months.
