Generac Generator Repair, Replacement, and Installation in Northern Utah
When your power goes out, your generator is supposed to take over.
But for many homeowners, that’s not what happens.
The system doesn’t start. The transfer switch fails. Or the generator runs—but can’t handle the load.
If you’re dealing with a failing system, you don’t need guesswork—you need a whole home generator repair company that knows how to diagnose, fix, and restore your system fast.
At Colonial Building Supply in Centerville, we specialize in whole home generator repair, system replacement, and full home standby installations across Northern Utah and beyond.
The Most Common Generac Generator Problems We See
Generac is one of the most widely used generator brands in Utah—but like any system, it requires maintenance and proper setup.
The majority of repair calls come down to a few core issues:
1. Generator Won’t Start
- Dead battery
- Faulty starter
- Fuel supply issues
- Control board errors
2. Generator Starts But Doesn’t Transfer Power
- Transfer switch failure
- Wiring or installation issues
- Communication errors between system components
3. Generator Runs But Can’t Handle the Home
- Undersized unit
- Load imbalance
- System not configured correctly
4. System Hasn’t Been Maintained
- Old oil and filters
- Battery degradation
- Internal wear from sitting unused
Most of these problems don’t show up until an outage—which is exactly when you need the system most.
