Our mobile process: how same-day service works
Booking is simple. Call , tell us the symptoms, share the model number, and send a quick photo of the nameplate. We block a 2-hour arrival window, then text when we’re 20 minutes out. On arrival, we do a safety check, verify oil level and fuel quality, and run through our 14-point test plan. We always load test with your RV air conditioner and microwave, so we’re proving real-world performance, not a no-load idle. Most jobs wrap in 90 minutes or less. If a part’s needed, we’ve usually got it. If not, we’ll same-day source from our suppliers or overnight it. You’ll see old parts, service photos, and a digital work order when we’re done. No black box service. You’ll know exactly what we did.

Maintenance that prevents 80% of generator failures
Want fewer headaches? Follow the maintenance schedule. According to Cummins Onan operator manuals, you should run the generator under load at least 2 hours each month, change oil every 150 hours or annually, and replace the air and fuel filters every 300 hours or two years, whichever comes first. We like plugs every 300 hours. If you run ethanol gas and store in heat, we push carb service sooner. Keep Stabil or PRI-G in the tank if you won’t run it monthly. Exercise under load matters. It bakes off moisture, keeps the windings dry, and keeps the carb from varnishing. Skip the exercise and you’ll pay later. Seen it hundreds of times.

Brands we service: Onan, Generac, Westinghouse, Predator
We work on the big names and the box-store specials. Onan MicroQuiet 4000, MicroQuiet 3600 LP, Marquis Gold 5500, QG and QD series. Generac Guardian RV sets and older Impact units. Westinghouse iGen inverters. Predator 3500s from Harbor Freight. Honda EU2200i and EU3000i portables, too. For Onan, we source OEM parts through Cummins. For Predator and Westinghouse, we stick to OE or quality aftermarket like NGK plugs and Denso starters. Honestly, I’d skip the no-name eBay carbs. They save $20 and cause $200 worth of surging. We’ve tried them so you don’t have to. If you’re unsure about your model, text us a photo of the dataplate. We’ll confirm parts on the spot.
Should you repair or replace your RV generator?
Here’s a quick way to decide. If repair cost is under 40% of replacement and the unit’s under 12 years old with decent hours, fix it. If you’re staring at a stator or rotor job plus a control board on a 20-year-old set, replacement wins.
| Scenario | Repair or Replace | Why | | --- | --- | --- | | Dirty carb, bad pump | Repair | Low cost, fast turnaround | | AVR and brushes | Repair | Parts available, solid fix | | Stator burn + bearings | Replace | High labor, uncertain outcome | | Crankcase knock | Replace | Base engine failure, not worth it |
Winner statement: If the quote crosses 50% of a comparable new unit, replacing is the smarter play. We’ll price both options so you can choose.
Local notes for RV owners: fuel, storage, and weather
Heat and humidity in can wreck fuel in weeks, not months. Ethanol blends attract moisture and form gum. If your rig sits near downtown , the civic center area, or out by the fairgrounds, keep the tank treated and exercise the gen monthly. Parking near the waterfront or at the main library’s open lot? Salt air means corrosion. We see more green fuzz on grounds and terminals. Keep covers intact, use dielectric grease, and check the exhaust hangers every spring. If you store in uncovered lots across , face the exhaust away from prevailing wind to reduce moisture intrusion. Small details. Big difference.
Emergency RV repair beyond the generator
We’re a full mobile rv repair outfit, not just gensets. If your AC won’t cool, fridge won’t get cold, or the water heater pops the breaker, we handle that too. Same crew, same truck. We also do rv roof leak repair and rv slide out repair. In season, we average 3,500+ jobs a year across , and about 38% of “generator problems” actually trace back to battery or transfer switch issues. So we bring a full electrical kit. If your trip is burning daylight, say the word. We’ll triage and get the biggest blocker fixed first. Fast and practical.

What we bring to the job: tools, parts, and proof
We don’t show up empty-handed. We carry NGK plugs, Onan fuel pumps, common carburetors, air and fuel filters, breakers, relays, AVRs, brushes, and a couple control boards that fail often. Tools include an infrared thermometer, carbon pile load tester, True RMS clamp meter, Wavetek scope, smoke machine for intake leaks, and a Megger for winding insulation checks. You’ll see real photos of your job in the final invoice along with test values. Voltage under load, Hertz, amperage by leg, and total harmonic distortion on inverter sets. If a shop can’t show you numbers, that’s a red flag. We show the math.
We verify voltage and frequency under your real loads, not just idle.
Real jobs we solved this month in li1li1/li2li2/CITY
Q: How much does rv generator repair cost in ?
A: Most jobs in run $189 to $985. Diagnostics are $129 in our normal service zones. Carb service lands $189 to $289. Carb replacement is $220 to $420 labor plus parts. Electrical issues like AVRs or control boards range $225 to $485 labor, parts vary by model.
Q: Can you repair my generator the same day?
A: Yes, if parts are in stock. We arrive within a 2-hour window, diagnose in 45 to 75 minutes, and complete most fixes on-site that day. If a specialty part’s needed, we can often source it same day locally or overnight it for next-day repair.
Q: What brands of RV generators do you work on?
A: We service Onan, Generac, Westinghouse, Predator, and Honda inverter portables, plus older units with parts availability. Text us a nameplate photo, and we’ll confirm model, parts, and ETA right away.
Q: Why does my generator start then die after a few seconds?
A: That symptom usually points to fuel delivery or the oil level safety circuit. Weak fuel pump, clogged filter, or gummed carb are common. We test fuel pressure, verify oil level and the low-oil switch, then clean or replace the carb if needed.
Q: How often should I service my RV generator?
A: Follow the Cummins Onan guidance: exercise under load 2 hours monthly, change oil every 150 hours or annually, and replace air and fuel filters every 300 hours or two years. We recommend spark plugs at 300 hours and a full inspection yearly.
Q: Will running the AC on generator hurt it?
A: No, as long as the generator is sized for the load and in good shape. We verify running watts, voltage, and frequency under your real loads. Soft-start kits on AC units can help older gensets handle compressor inrush without bogging.
Q: Do you offer a warranty on repairs?
A: Yes. We warranty labor for 12 months and honor manufacturer warranties on parts. If a repaired item fails inside the warranty window, we schedule a priority return visit to make it right.
Q: Do you work in campgrounds and storage lots?
A: Absolutely. We serve campgrounds, driveways, and gated storage across . We coordinate with managers for access and comply with quiet hours and safety rules during testing and load runs.
Q: Is it okay to use ethanol gas in my generator?
A: You can, but it’s harder on carbs, especially in heat. If you use ethanol blends, keep stabilizer in the tank and exercise the generator monthly. Non-ethanol fuel plus regular runs prevents most surging and no-start issues we see.
