What Generator Repair and Service Covers
Diagnostic Inspection
Every repair starts with a thorough diagnosis. Our NATE-certified technicians systematically evaluate your generator's engine, electrical systems, fuel delivery, and controls to pinpoint exactly what's failing — not just the symptom, but the root cause. With over 25 years of experience servicing generators across Mobile and Baldwin County, we've seen every failure mode and know where to look first.
Startup and Load Testing
A generator that starts in ideal conditions may still fail under real-world demand. We run your unit through a full startup sequence and apply an actual electrical load to confirm it transfers power correctly, holds voltage without dropping, and shuts down safely — exactly as it would during a storm outage.
Battery and Charging System Service
A dead or weak battery is one of the most common reasons a standby generator won't start — and one of the easiest problems to prevent. We test the battery's cold-cranking capacity, measure charging voltage, and inspect terminals and connections for corrosion or looseness. If the battery isn't holding a charge or the charging system isn't maintaining it between test cycles, we'll replace what's needed before it becomes a problem during a real outage.
Fuel and Fluid Service
We inspect fuel lines, filters, and carburetor or fuel injector components for blockages, leaks, or deterioration that could prevent the engine from running cleanly or at all. Stale fuel is a common culprit in generators that sit idle between storm seasons — we identify fuel quality issues and address them before they strand you without power.
Low or degraded fluids cause premature wear and unexpected shutdowns. We check oil and coolant levels and condition, change what needs changing, and make sure your engine is properly protected for the next time it's called on to run.
Warning Signs Your Generator Needs Attention Now
If your generator is showing any of the following symptoms, don't wait for the next storm to find out whether it will hold up. Catching a problem early is almost always faster and less expensive than dealing with a full failure.
- Won't start at all — often a dead battery, fuel issue, or failed starter component
- Starts but shuts off shortly after — typically a fuel delivery problem, dirty carburetor, or a sensor fault
- Runs rough or surges — usually caused by stale fuel, a clogged fuel filter, or air intake restrictions
- Cranks but won't fire — points to a stuck choke, weak spark, or blocked fuel system
- Runs but doesn't restore power to your home — almost always a transfer switch failure, not the engine itself
- Visible oil or fuel leaks — small leaks become big problems under load; address them before the next outage
- Warning lights or fault codes on the control panel — these exist for a reason and shouldn't be reset without a proper diagnosis
Why Standby Generator Maintenance Isn't Optional
Most generator failures are preventable. A standby generator that sits idle for months between storms is exactly the kind of equipment that fails when it's needed most — not because it's low quality, but because it wasn't maintained. Fuel degrades. Oil breaks down. Batteries lose their charge. Belts crack. Connections corrode.
Scheduling periodic standby generator maintenance — at minimum once a year, ideally twice — is the single most effective way to ensure your unit starts and performs when the power goes out. We recommend pairing your generator maintenance with a seasonal tune-up so both your HVAC system and your backup power are ready before storm season begins.

Frequently Asked Questions About Generator Repair
Why won't my generator start?
The most common causes are a dead or discharged battery, a fuel delivery problem such as a clogged filter or degraded fuel, or a stuck choke. A diagnostic visit will identify the specific cause quickly so we can get the unit running again.How often should a standby generator be serviced?
At minimum once a year, though twice a year is ideal for generators in high-use areas or homes where reliable backup power is critical. Regular standby generator maintenance catches fluid degradation, battery wear, and component issues before they become failures.My generator runs but my house has no power — what's wrong?
This is almost always a transfer switch issue. The transfer switch is the component that routes power from your generator to your home's electrical panel. When it fails, the generator can run normally while your home stays without power. This is a repair we handle regularly.Can you service any brand of standby generator?
Yes. Our technicians are trained to diagnose and repair all major standby generator brands. Whether your unit is a Generac, Kohler, Briggs & Stratton, or another manufacturer, we can troubleshoot and service it.What's included in a generator tune-up?
A standard generator tune-up covers oil and filter change, spark plug inspection or replacement, air filter service, battery and charging system test, fuel system inspection, load test, transfer switch check, and verification of the auto-exercise cycle. The goal is to confirm every system is functioning and the unit will start reliably under load.
