Whole Home Generator Repair
A standby generator that will not start during an outage needs fixing today, not next week. GenerX handles generator repair across Florida, Tennessee and Kentucky for every major brand, with factory trained technicians and parts on the truck.
Generator Repair
Generator Repair for Every Major Brand
A standby generator matters on exactly one day: the day the grid goes down. That is the worst possible morning to learn it will not run. GenerX technicians repair the whole system rather than just the engine, including the transfer switch that moves your house onto backup power, the battery and charger that crank it, the fuel line that feeds it, and the controller that governs all of it.
We sell and install Generac, and we repair what other companies installed. If the badge on your unit reads Kohler, Cummins, CAT, Briggs & Stratton, Champion or Honeywell, we still take the call.
Warning Signs
Signs Your Generator Needs Repair
Most failures announce themselves weeks before the storm. Call for service if you notice any of these.
What We Fix
Common Generator Repairs
Six problems account for most of the repair calls our technicians run. All six are fixable, and a technician carrying the right part fixes most of them on the first visit.
Battery & Charger Failures
A flat battery is the single most common reason a standby generator refuses to start. We test the battery, the charger and the charging circuit, then replace whichever one actually failed.
Transfer Switch Faults
The automatic transfer switch is what moves your home onto generator power. When it sticks, the generator runs and the house stays dark. We test, repair and replace switches.
Fuel Delivery Problems
Regulators, valves and undersized lines that cannot hold pressure under load will stall an engine minutes after it starts. We measure fuel pressure at the unit and correct what is starving it.
Controller & Fault Codes
Modern controllers log exactly what went wrong and when. We read the history, update the firmware when the board needs it, and replace the controller when the board itself has failed.
Engine & Cooling Repairs
Oil leaks, overheating, worn plugs, clogged filters and failed sensors all make a generator shut down to protect itself. We repair the cause rather than clearing the alarm.
Wiring & Enclosure Damage
Corrosion, rodents and storm debris take out wiring harnesses, sensors and enclosure hardware. Coastal installations in Florida see this more than anywhere else we work.
Emergency Service
Emergency Generator Repair, Around the Clock
Outages keep no business hours, so neither does our service line. GenerX runs 24/7 phone support for emergencies: a failure at 2am on a Sunday gets the same call as one at noon on a Tuesday. Reach the service team at 833-496-9436.
During named storms and regional outages, technicians work emergency repair calls first. Customers on a Power or Premier service plan hold priority in that queue, which is the practical reason those plans exist.
What to Expect
How a Repair Visit Works
Three steps, and you know where the job stands at each one.
You Call, We Schedule
Tell us the brand, the model and what the generator is doing. That is usually enough for the technician to arrive with the likely part already on the truck.
We Diagnose On Site
The technician pulls the controller history, tests the battery, checks fuel pressure and exercises the transfer switch, then identifies the actual cause before quoting any work.
We Repair and Test
You approve the work before it starts. When the repair is finished, the technician runs the system through the transfer switch so you watch it carry the house before anyone leaves.
Fewer Repairs
Most Repairs Are Preventable
Nearly every failure listed above starts small: a battery reading low, a fuel pressure number drifting out of spec, a filter that should have been changed last spring. Annual maintenance catches those while they are still cheap to fix, and it is also what keeps your manufacturer and dealer warranty valid. Every GenerX installation carries the 12 year Power Plus Warranty on parts and labor at no extra cost.
FAQs
Generator Repair Questions
Common questions about generator repair and emergency service
Do you repair generators you did not install?
Yes. We sell and install Generac, and we repair standby generators from Kohler, Cummins, CAT, Briggs & Stratton, Champion and Honeywell as well, whichever company originally put the unit in.
My generator will not start. What is the most likely cause?
The battery, more often than anything else. A failed charger, a controller fault or low fuel pressure produce the same symptom, though, so the technician tests all of them before replacing any parts.
The generator is running but my power is still out. Why?
That usually points at the automatic transfer switch rather than the generator. The switch is what moves your home from utility power onto generator power, and when it sticks the engine runs while the house stays dark. We test, repair and replace transfer switches.
Do you offer emergency generator repair?
Yes. GenerX runs 24/7 phone support for emergencies, so you can reach the service team at 833-496-9436 at any hour. During named storms and regional outages, technicians work emergency calls first, and customers on a Power or Premier service plan hold priority in that queue.
How do I keep repairs to a minimum?
Have the generator serviced once a year. Routine maintenance catches a weak battery or a drifting fuel pressure reading while the fix is still small, and it keeps your warranty active. Ask about our maintenance and service plans.
Where do you provide generator repair?
Across Florida, Tennessee and Kentucky, from local technician teams rather than a single central depot. Find your city on our service areas page.
