Power outages can disrupt everything. No lights, no heat or AC, and no way to keep the food cold or work from home. That’s why so many homeowners and businesses depend on Generac generators to keep life moving when the grid goes down.
But even the most reliable backup system needs attention. If your generator won’t start or runs with issues, it can leave you unprotected at the worst time. That’s where professional Generac repair service comes in.
In this guide, we’ll cover what to watch for, when to call for help, and how to make sure your generator stays ready for a power outage.
Signs Your Generac Standby Generator Needs Repair
Knowing when something isn’t right can help you catch small problems before they turn into bigger ones. Here are the most common signs your generator may need professional attention.
It Won’t Start
If your generator doesn’t start on its own or when you try to start it yourself, get it checked immediately. This could point to battery failure, fuel delivery issues, or electrical faults. Even if it eventually starts after a few tries, it’s best to request service before the next outage.
You See a Warning Light
Generac units are designed to alert you when something’s off. Flashing lights or error codes on the control panel are a clear signal that the system has detected a fault. These messages help technicians pinpoint issues during the repair visit.
Unusual Noises or Smells
Rattling, grinding, or clicking sounds may indicate mechanical problems. If you smell fuel or burning, shut the unit down and call for help. These signs often point to leaks, overheating, or wiring problems.
Power Output Is Inconsistent
If your lights flicker or connected systems cut out while the generator is running, the issue might lie in the voltage regulation or engine performance. Reliable backup power depends on steady output.
It Runs Too Long or Too Often
Some generators run longer than needed or turn on more frequently than normal. This can mean a faulty sensor or an issue with your installation setup. It’s worth having a technician take a look.
When Should You Call a Certified Technician?
You can handle simple tasks like checking oil, testing the battery, or running a weekly self-test. These help keep your generator ready between visits.
But if the unit won’t start, shows error codes, or shuts down during use, it’s time to call a certified technician. Internal issues like fuel blockages or control panel failures need expert attention and could void your warranty if handled incorrectly.
Professional help adds peace of mind. It’s a safer, more reliable way to fix problems and offers the convenience of knowing the job’s done right.
How Often Should You Do Generator Maintenance?
Routine service keeps your generator reliable. In most cases, Generac recommends servicing your unit at least once a year, or after every 200 hours of use, whichever comes first.
If your generator runs during extended outages or goes months without being used, it’s a good idea to check it seasonally. That includes testing the battery, changing the oil, replacing the air filter, and confirming the system starts correctly.
After you install a new generator, set up a maintenance schedule right away. Many local service providers offer seasonal checkups or annual plans to keep your system in good shape year-round.
How Much Does a Generac Generator Repair Cost?
The cost to repair a Generac generator typically ranges from $171 to $395, with most customers paying around $273 on average. This covers common issues like battery replacements, fuel line repairs, or control panel resets.
More complex problems, like a faulty transfer switch or control board, may fall at the higher end of that range or slightly above. Labor costs vary based on your location and whether you need emergency service.
