Expert Generator Repair in McKinney, TX
A broken generator is just a lawn ornament. When your backup power system fails, Top Flow Plumbing Co. is here to get it running again. We provide fast, certified generator-repair for all major brands, ensuring you aren't left helpless during the next power outage.
Common Generator Failures
Failure to Start
You hit the button, but nothing happens. This is often caused by a dead battery, a bad starter, or a blown fuse that needs immediate replacement.
Rough Running
If your engine is sputtering, surging, or hunting for idle, it likely has a clogged carburetor or fuel system issue that requires professional generator-repair.
Error Codes
Seeing a red light or a cryptic code like "RPM Loss" or "Overcrank"? We have the diagnostic tools to decode and fix these specific faults.
We Bring The Power Back
Modern generators are complex machines with advanced electronics. Guessing at the problem can cause further damage. Our technicians are trained to troubleshoot both the engine mechanics and the digital control logic. Whether you have a portable unit that won't turn over or a whole-home standby system showing an error code, get started with a professional diagnostic to pinpoint the issue fast.
On-Site Service
We come to you with a fully stocked truck.
Warranty Work
We use OEM parts to keep your warranty intact.
Restoring Reliability In 4 Steps
Diagnostic Scan
We hook up our diagnostic computer to read the fault history and inspect physical components like spark plugs and fuel lines.
Upfront Quote
Before turning a wrench, we explain exactly what is broken and provide a flat-rate price for the generator-repair.
Precision Fix
We replace the faulty components, clean the connections, and ensure the system is calibrated to factory specifications.
Load Test
We run the generator under a simulated electrical load to verify it can handle your home's power demands without stalling.
Why Choose Top Flow?
Rapid Response
We know that when a generator is down, time is of the essence. We prioritize repair calls, especially when severe weather is in the forecast.
Honest Diagnostics
We will never sell you a new generator if your current one can be fixed affordably. We believe in transparency and integrity.
Lasting Results
We don't just put a band-aid on the problem. We fix the root cause so you don't have to call us back for the same issue next week.
A Broken Generator Is A False Sense Of Security
There is nothing worse than thinking you are protected, only to find out your generator doesn't work when the power grid fails. Neglected repairs often lead to catastrophic engine failure, forcing you to buy a whole new unit. If your generator is making strange noises or showing a warning light, do not ignore it. Visit our contact page immediately to schedule a repair before the next storm hits.
