Pre-storm standby generator service
Scheduled Generator Maintenance in Charlotte, NC
July highs here average 90 degrees and January lows sit just under freezing, both outside the 40 to 85 degree band in Generac's standard schedule. That puts standby units across Charlotte on yearly oil changes, and we keep them there.

What a serviced standby unit gives a Charlotte home
Maintenance is how most problems get found before an outage finds them for you. If a visit turns up a worn or failed part, the fix is quoted as generator repair in Charlotte, written up separately so you can decide before any part is swapped.
Cranks on a freezing dawn
We load-test the battery and replace it once it fades, because a weak battery shows itself on a freezing January morning, not a mild afternoon.
Ready for a long ice outage
Fresh oil and a new filter ready the engine for long runs, like the December 2002 ice storm, when 172,000-plus Charlotte customers were still dark four days in.
A real transfer, not a drill
We cut utility power on purpose and watch the transfer switch move your circuits, because the weekly exercise run usually leaves the house on utility power.
Enclosure cleared of oak debris
Under the big oaks of Myers Park and Dilworth, leaves and rodent nests pack into enclosures, so we clear the louvers and check wiring for chew marks.
Fault history read early
We read the controller's fault history and apply firmware updates where the manufacturer offers them, so an October warning is not discovered mid-outage in December.
Warranty kept valid
Service on the manufacturer's interval, with hours and tasks written down, helps keep a Generac or Kohler warranty valid when a covered part fails later.
Why Charlotte generator owners book upkeep with Roland Black
Certified on Generac and Kohler
Our technicians are certified on both brands, so we follow each manufacturer's own interval for oil, plugs and air filters instead of one generic checklist.
Run hours read, not guessed
We pull the run hours from the controller before touching anything, because a unit that carried a house through a long ice outage may be due early.
Visits timed to two seasons
We can book a spring visit ahead of the hurricane season that brought Hugo through in September 1989, and a November visit before the ice storms Charlotte sees more often than snow.
Electricians on the switch
Our licensed electricians (NC license #34773) test the transfer switch and panel connections themselves, so the electrical half of the system gets the same attention as the engine.
Answered between visits
The Gastonia shop has operated since 1973 and takes calls 24/7, so a fault code that appears between visits, even in the middle of an outage, gets answered.
Charlotte generator maintenance, answered
Generac's standard schedule calls for oil and filter every two years or 200 hours, but it tightens to every year or 100 hours where temperatures run below 40 or above 85 degrees. Charlotte's normal July high is 90.3 degrees, so we treat yearly service as the baseline here, with an earlier visit if a long outage piled on run hours.
Routine service replaces wear parts on an installation that was already permitted and inspected. Work that changes the electrical system, such as replacing a transfer switch, is different. For Charlotte homes those permits come from Mecklenburg County Code Enforcement, not the city, and we file them and book the inspection before that work is done.
A weekly self-run proves the engine turns over, not that it can carry the house, so a sticking transfer switch or tired battery can hide until a real outage. During Winter Storm Elliott on December 24, 2022, Duke cut and restored Carolinas customers in planned blocks, something it had never done before. Every cut is another transfer, so we prove the switch under load before winter.
