Sparky's Mobile RV Repair
Own this business? Update this listingSparky's Mobile RV Repair is a mobile RV repair business based in Holly Lake Ranch, Texas. It calls itself "a strictly mobile repair business," so it comes to your rig at a campground, storage lot or driveway, and you do not take the RV to a shop. Ask whether it reaches your site before you book.
It works on RV appliances and the living quarters of travel trailers, bumper pulls, fifth wheels, class A, B and C motor homes, diesel pushers and toy haulers. Systems it lists include furnaces, water heaters, plumbing, electrical, AC units and heat pumps, rubber roof coating, battery testing and replacement, inverters and converters. It names Dometic and Maxx Air as brands it services. It does not work on engines, axles, brakes or hitch work, so a chassis problem needs another shop.
The hourly rate is $125 per hour for one technician, plus $50 per hour for each apprentice needed. Beyond that, the answer is "ask for trip quote." Its approximate installed prices leave out the trip charge, but several items done in one visit carry only one trip charge, which is worth knowing before you book. Emergency calls after normal hours cost 1.5 x the normal labor rate. Its base labor price for installing an AC unit or heat pump is $475, and furnace repair or water heater replacement runs $275 / $345. Cash payments get a 10% cash discount, and Square takes all major credit cards. Hours are 8:00am to 5:00pm Monday through Friday and 9:00am to 2:00pm Saturday, with Sunday by appointment only. Its posted hours for today read 09:00 am to 05:00 pm, so confirm when you call. Ask about a diagnostic fee too.
The owner is a licensed electrician in Texas with "over 40 years as a licensed electrician," and the business has been doing RV repair for over 7 years. That background matters when the trouble is wiring, since a dead outlet or a converter that will not charge can look like an appliance problem. The business offers "100% Satisfaction Guaranteed," and Google rates it 4.6 stars from 17 reviews. Calls are returned "usually within a few business days," so for a breakdown that cannot wait, ask about after-hours service first.
This is a good fit for an owner near Holly Lake Ranch with a furnace, water heater or AC problem that can wait a few days for a callback, or for one who wants electrical and appliance work done where the rig is parked.
