A standby generator that fails a self-test, will not start, or displays a warning is not an ignorable problem that can be put off. Iowa thunderstorms, high winds, and winter freezes put backup power systems to work when homeowners need them most.

With more than 80 years of service and Generac Pro Dealer expertise, we diagnose generator problems and restore backup power systems.

Signs Your Generator Needs Repair
A generator not starting is an obvious problem, but other changes can signal trouble before the system fails completely. Schedule standby generator service for failed self-tests, warning lights, unusual noises, fluid leaks, or unstable electrical output.
Battery problems, fuel delivery issues, failed sensors or controls, worn components, and transfer switch faults can prevent normal operation. Our electricians inspect the generator and its connections instead of replacing parts based on symptoms alone.
Generator systems are connected to your home's electrical equipment, so problems involving wiring, controls, or power delivery require professional attention. Our electrical services handle any other related electrical concerns identified during diagnosis.
How We Diagnose and Repair Your Generator
Generator troubleshooting starts with a complete system evaluation. We test battery condition, inspect fluids and filters, check fuel delivery, examine controls and wiring, measure electrical output, and verify transfer switch operation.
The automatic transfer switch detects a utility outage and transfers the home's electrical load to generator power. A failed switch, control problem, or wiring fault can prevent that transfer even when the generator itself starts. Our licensed electricians test the switch and connections to identify the source of the failure.
Once testing is complete, we explain what failed, what needs to be repaired, and what is required to return the generator to normal operation.
Repair or Replace?
An isolated component failure on a generator that remains in good condition is a strong repair candidate. Battery, sensor, control, fuel-delivery, or transfer-switch problems do not automatically mean the entire generator needs replacement.
Repeated major failures, extensive deterioration, or insufficient capacity for the home's current backup-power needs change the equation. We evaluate equipment condition, repair history, and current electrical needs before discussing replacement.
Maintenance That Keeps You Powered Through Iowa Weather
Regular generator maintenance prepares the system for the conditions that cause outages across Iowa. We inspect the generator, test the battery, check fluids and filters, verify fuel delivery, confirm exercise operation, and test the transfer switch according to the equipment's service requirements.
Spring and summer bring severe thunderstorms and high winds, while fall preparation matters before freezing temperatures and winter storms arrive. An outage during extreme weather can interrupt heating equipment, refrigeration, and electrically powered sump pumps.
Backup power is one part of outage preparation. Whole-home surge protection protects connected electrical equipment from damaging voltage spikes, while a sump pump battery backup keeps basement water protection available when utility power is down.

Battery failure, fuel delivery problems, control faults, failed sensors, wiring problems, or worn components can prevent a standby generator from starting. We test the system to identify the cause before recommending a repair.
Follow the generator manufacturer's service schedule for professional inspection, testing, oil and filter service, and other required maintenance. Schedule testing before severe storm and winter seasons so operating problems are identified before an outage.
Repair makes sense when the generator remains in good condition and has an isolated component failure. Repeated major repairs, extensive deterioration, or inadequate capacity for your current backup-power needs are reasons to discuss replacement.
Schedule generator service before the next outage. A failed self-test indicates the system detected an operating problem that needs diagnosis before you depend on the generator for backup power.
