Generators are the system that gets used least and complains loudest. Most RV generators sit unused for 90% of their life, then get fired up for a tailgate or a power outage and refuse to start. We get a lot of "I haven't used it in two years and now it won't run" calls. The fix is almost always fuel-related - varnished gas in the carb, dirty fuel filter, or a fuel pump that's gummed up.

The other big category is "runs but acts up" - surging RPM, low voltage, won't take a load. Those are usually governor issues, voltage regulator problems, or load circuit issues. We diagnose all three at your site.

Why Generator Service Fails Faster in Florida

RV generators fail from disuse more than from use. Fuel sitting in a carburetor for 6+ months turns to varnish, which clogs jets and seals. Once the fuel system is gummed up, you can't start, and trying to start it just makes things worse. Annual service prevents almost all of this.

The other failure mode is hour-related: at 1,500-2,000 hours, most RV generators need a major service - new rings, new valves, or in some cases a full rebuild. Heat is the primary stressor in Florida, and high ambient temps mean the generator runs hotter than it would in a milder climate.

What We Fix - Generator Service

What Our Generator Service Service Includes

Generator service calls start with a function test - we crank, listen for spark and fuel, check voltage output, and measure load capacity. That tells us within 20 minutes whether it's fuel, ignition, or load.

From there it's a parts swap and tune. Annual service runs $185-$345. Carburetor cleanings run $385-$685. Full rebuilds run $2,250-$3,500.

Onan & Cummins specialists

Onan QG, RV QG, and Cummins generator service. We have the specialty tools and stocked parts.

Annual maintenance

Oil, filter, fuel filter, spark plug, and air filter service - the routine stuff that prevents 90% of failures.

Carburetor service

Carburetor rebuild, jet cleaning, and float adjustment. Most no-start calls are carb issues.

Voltage regulation

Voltage regulator replacement, AVR service, and brushless rotor inspection.

  • Auto-start kit installation: $585-$985

Florida-Specific Generator Service Considerations

Florida heat shortens generator service intervals. Manufacturers spec annual service at 150 hours - we recommend annual service or every 100 hours, whichever comes first. The high ambient temps make oil break down faster, and you'd rather change oil twice as often as rebuild a generator at 1,500 hours instead of 2,000.

Hurricane season specifically is when generators get used hard. If you ran your generator continuously for 3 days during a power outage, schedule a service immediately after - that's a service interval all by itself.

Emergency Generator Service Service Across Florida

Generator failure during a power outage or hurricane is borderline-emergency. We bump those calls and try to get someone out next-day. Tell whoever picks up the phone that it's a power-outage emergency and we'll prioritize.

If you can't get the generator started during an outage, focus on conserving battery and getting back to shore power. Don't keep cranking - you'll drain the start battery and make the eventual repair worse.

Specialized Repairs

Generator Service Specialties We Handle

Common subspecialties under generator service - all done at your location, all in one visit when possible.

Annual Maintenance

Oil, filter, fuel filter, spark plug, and air filter. The service that prevents most failures.

Carburetor Service

Cleaning, rebuilding, and float adjustment. Most no-start calls are carb work.

Voltage Regulation

AVR replacement, voltage regulator service, and brushless rotor inspection.

Starting Circuit

Starter motor replacement, solenoid service, and starting circuit wiring repair.

Major Service

Rings, valves, and head gasket service. Done at the 1,500-2,000 hour mark.

Auto-Start Kit

Installation of auto-start systems that fire the generator when battery voltage drops. Worth it for boondockers.

FAQ

Generator Service - Common Questions

Straight answers from our generator service call log.

My generator won't start after sitting all winter - what is it?

Almost always a clogged carburetor from varnished fuel. Cleaning and rebuild runs $385-$685. Prevent it next year by either running the generator monthly or fuel-stabilizing for storage. - Marc

How often should I service my Onan?

Annually or every 100 hours, whichever comes first - in Florida, definitely annually. We do it as a $245-$385 service.

My generator runs but the AC won't kick on - what is it?

Could be the generator can't supply enough current, or the rig's transfer switch isn't seeing the generator. We test both - $145 diagnostic, repair quoted separately.

Can you rebuild an old Onan?

Most Onan QG and RV QG units, yes. Older Onans (the 4kW and 6.5kW gas units from 20+ years ago) get harder - parts availability is the issue. We'll be honest about whether it's worth rebuilding.

Should I run my generator weekly?

Monthly under load is fine - run it for 30 minutes with at least 50% load (i.e. AC running). Weekly is overkill. The point is to keep fuel fresh and seals lubricated.

My generator surges RPM - is it dying?

Probably not - usually a governor issue or a fuel-system problem. Both are diagnosable at your site - $145-$385 for the diagnosis and most fixes are sub-$500. - Marc

Can you install an auto-start kit?

Yes - we do Onan AutoGen and Cummins Smartgen installs regularly. About $585-$985 with parts and labor depending on which kit and which gen-set.

How long do RV generators last?

Onan QG and RV QG units run 3,000-5,000 hours with regular service. Older units go 1,500-2,500 hours. Big deciding factor is how much they've been used vs. abandoned.

Will an inverter replace my generator?

For some uses, yes. A big inverter (3,000W+) plus a big lithium bank can run an AC for several hours. But it doesn't recharge - if you're boondocking longer than the bank lasts, you still need the gen-set or solar.

Do you do propane generator service?

Yes - Onan QG LP units especially. Propane gen-sets are easier to maintain (no fuel varnish issues) but they run hotter and tend to need head-gasket service earlier. - Marc
