What a Concord repair should leave you with

Some units are worth fixing and some are not, and we say which after the diagnosis, never before it. When a unit has reached the end of its life, the conversation turns to generator installation in Concord. When it has not, these are the results a repair should deliver.

  • Starts on a cold morning

    A fresh battery and a working charger give the engine the cranking power it needs on mornings like November 29, 2023, when Cabarrus lines dropped before dawn.

  • Fault codes traced, not reset

    Each code is followed to its cause, such as a failed sensor or low oil pressure, rather than cleared and left to reappear in the next Concord outage.

  • Clean hand-back to the grid

    A healthy transfer switch returns the house to Concord Electric Systems or Duke Energy power once service is steady, then lets the engine cool down and shut off.

  • Misfires and stumbles cured

    Worn spark plugs and failing ignition coils are replaced when an engine misfires under load, so the unit carries a Concord house at full output instead of sputtering.

  • Exhaust and enclosure checked

    Cracked exhaust parts, loose enclosure panels and blocked louvers are found and fixed, so a unit beside a Concord house runs safely and stays sealed against the weather.

  • Weekly self-test back on

    The automatic exercise cycle is reset and confirmed, so the unit runs itself between Concord outages and flags a problem while the grid is still up.

What Concord homeowners get when they call us

  • You approve every part

    Nothing is ordered until you have seen what failed and agreed to the repair, so a Concord visit never turns into parts swapped one after another on a guess.

  • Certified, and not brand-bound

    Our Generac and Kohler certification does not limit us: we repair other brands of home standby units too, including whatever make the previous owner of your Concord house chose.

  • Electricians for the switch side

    Transfer switch and panel faults are electrical work, handled by our licensed electricians under license #34773. Repairs that need a permit go through Cabarrus County Construction Standards.

  • Phones staffed through the night

    Generators fail during outages, not office hours. Our line is open 24/7, so you can report a unit that quit before dawn without waiting for Monday morning.

  • A straight repair-or-replace call

    If a unit is past saving, we tell you plainly and quote a replacement instead, which comes with our 10-year warranty and financing options.

Straight answers for Concord generator owners

We start at the controller, reading its event history and any active alarm. Then we test the battery and charger, check the fuel supply and ignition, and run the transfer switch through an outage with the house on it. You see what failed and what the fix involves before you approve anything, and if a permit is needed, we file it with Cabarrus County Construction Standards.

That points to the transfer switch or its controller, which watches utility voltage and decides when to hand the house back. Nights like the delivery point fire of June 2017, when power came back after 1 a.m. and dropped again around 5, are when a weak switch gives itself away. We test the sensing circuit and watch a full hand-back before we leave.

Yes. We work on any brand of home standby generator, and we are Generac and Kohler certified. Concord homes range from North Union Street houses built after 1870 to Afton Village homes from the late 1990s onward, and a generator can change owners with any of them. We diagnose first, then quote the repair, or a replacement if parts or age rule a repair out.
