Generator Repair Services in Lawrence, Topeka, and Baldwin

Kansas weather keeps you guessing. One week it’s windy, the next brings thunderstorms, and in winter an ice storm can knock out power for hours or even days. That’s when a standby generator makes all the difference.
It keeps the lights on, the heat running, and essentials like refrigerators, sump pumps, and medical equipment working. But just like any other system in your home, a generator needs care and sometimes repairs.
Dunco Heating, Cooling & Plumbing provides professional generator repair in Lawrence, Topeka, and Baldwin so you’re not left in the dark.
How Generators Work
When the power goes out, a standby generator automatically starts up. It pulls energy from a fuel source like natural gas, propane, or diesel, converts it into electricity, and sends that power to your home’s electrical panel.
Depending on how it’s set up, a generator can run selected circuits or power the entire house.
For Kansas families who deal with unpredictable outages, that reliability is worth a lot.
Signs Your Generator Needs Repair
Most generators give you warning signs before they fail completely. Call for service if you notice:
- Trouble starting or cranking for too long before it kicks on
- The generator runs but isn’t producing power
- Odd noises like knocking or grinding
- Strong fuel smells or signs of leaks
- Error codes on the control panel
- The system shutting down mid-cycle
- Excessive vibration while running
These issues won’t fix themselves. Taking care of them early is always better than waiting until the next storm.
Quick Checks On Your Generator Before You Call
There are a few things you can look at yourself before scheduling a repair for your generator:
- Make sure there’s enough fuel and that gas or propane lines are working
- Check the battery; weak or corroded batteries are a common cause of startup problems
- Try the reset switch if your model has one
- Check the oil level; low oil can shut the unit down automatically
- Look at the control panel for error codes
If your generator still won’t start or runs poorly, it’s time to call a professional.
Repair or Replace Your Generator?
Whether a generator is worth repairing depends on its age and condition.
- Repair makes sense if: the unit is less than 10 years old, has been maintained regularly, and the issue is relatively minor.
- Replacement is better if: the generator is 15 years or older, breaks down often, or the repair cost is close to half the price of a new system.
A newer unit with a bad battery is usually an easy fix. An older system with major engine or alternator damage is often more cost-effective to replace.
Dunco’s technicians can walk you through the options so you can make the best decision for your home.
