# RV Service > What actually happens during a service appointment, how diagnosis is billed, and how findings turn into decisions. Source: https://ocrv.info/rv-service An RV service visit at OCRV Center is a scheduled appointment to evaluate, diagnose and repair house systems: electrical, plumbing, propane, appliances, generators, rooftop air conditioning, slides and awnings. It produces a written findings list with priced options rather than an open ended repair authorization. Service is different from maintenance and different from body work. Maintenance is what an owner schedules to keep something from breaking. Body work is what happens after an impact. Service is the middle case: something is not working correctly right now, the cause is not obvious, and the first job is to determine what is actually wrong before anyone quotes a repair. That determination is the service visit, and it has its own structure and its own billing. The reason to be explicit about this is that owners frequently arrive expecting a quote and receive a diagnosis instead. A refrigerator that will not cool has at least six plausible causes across two power sources. An inverter that trips has as many. Guessing at a part and installing it is the fastest way to spend money without fixing anything, so the shop diagnoses first, writes up what it found, and prices the repair against that finding rather than against the complaint. All service work happens in shop at the Yorba Linda facility. Owners in Eastvale typically drop the coach and collect it, which suits systems work because much of it involves running the system through cycles rather than a continuous hands on operation. A generator load test, a refrigerator cooling verification and a leak down check all take real time during which nothing productive happens if somebody is waiting in the lobby. ## What a Service Appointment Actually Covers The scope of a service visit is the house side of the vehicle: twelve volt distribution, batteries and charging, converters and inverters, shore power and transfer switches, solar arrays, generators, propane distribution, fresh and waste water systems, water heaters, furnaces, refrigerators, rooftop air conditioning, slide mechanisms and awning operation. Anything that runs, cycles, heats, cools or moves belongs in this category rather than in body work. What it does not cover is chassis mechanical work. Engine, transmission and drivetrain service are not performed at this facility, and there is no emission testing or commercial safety inspection. Owners regularly combine a house service visit with a separate chassis appointment elsewhere, scheduling them in sequence so the coach is only out of use once. The shop is happy to coordinate timing around that when it is planned in advance. - Twelve volt, shore power, inverter, converter and transfer switch - Batteries, charging systems and solar arrays - Generator run, load test and service - Propane distribution, leak testing and appliance ignition - Fresh water, waste, water heater and fixture operation - Rooftop air conditioning, furnace, refrigerator and slide operation ## How Diagnosis Is Structured and Billed Diagnosis starts with reproducing the complaint. That sounds obvious and it is skipped constantly. A symptom that appears only on propane, only above a certain temperature, or only when a second appliance is running tells you far more than the symptom itself does. The service writer records the conditions from the owner, then the technician reproduces them before touching anything, because a fault that cannot be reproduced cannot be verified as fixed either. From there it is systematic elimination against the actual circuit or system, not parts replacement by guess. In depth diagnostic time bills at the posted rate of $285 per hour with a one hour minimum and is credited against an authorized repair. RV systems estimates covering slides, awnings, water, electrical and generators carry a $150 charge, also credited. Mechanical and electrical repair labor bills at $260 per hour. Those figures are posted rather than negotiated per job. ## Inspection and Evaluation as a Standalone Service Not every service visit starts with a complaint. Owners buying a used coach, preparing for a long trip, returning a unit to service after storage, or trying to build a budget for the year all benefit from a comprehensive inspection. That visit runs the whole house systematically and produces a written findings list rather than a repair. Nothing gets fixed unless the owner authorizes it after reading what was found. The output is what makes it worthwhile. A findings list separates items into what is failing now, what is degrading and will need attention within a season, and what is merely worn but functional. That structure lets an owner spend in the right order instead of addressing whatever was mentioned most recently. For a pre purchase inspection it also puts a number on deferred maintenance before money changes hands. - Pre purchase evaluation before buying a used coach - Return to service check after extended storage - Pre trip verification before a long or remote trip - Annual condition report for budgeting repair priorities - Documentation of condition for a sale or an insurance file ## Turning Findings Into Decisions A findings list only helps if it is priced and prioritized. Each item gets an estimated labor figure against the posted rate, a parts cost, and a plain statement of consequence if it goes unaddressed. Some items compound. A failing slide seal leads to wall damage. A sulfated battery bank kills a converter. A leaking water heater fitting rots a floor. Those get flagged as priority regardless of how minor they look on the list. Other items are genuinely optional. A furnace that runs but cycles noisily, a refrigerator door seal that is imperfect, a stained ceiling panel over a leak that has already been fixed. Those go in a lower tier so the owner can decide. Nothing gets performed without written authorization, and parts over a certain value require a deposit at the time the order is placed. Being explicit about all of this at the counter avoids the uncomfortable version of the conversation later. ## Scheduling, Drop Off and Turnaround Service work moves faster than body work but it still depends on parts. Many appliance and electrical components are available quickly. Some, particularly for older or discontinued units, are not. Scheduling therefore starts with a diagnosis appointment, and the repair gets scheduled once the parts situation is known. Trying to reserve a repair slot before diagnosis usually wastes the slot. Hours are Monday through Friday from 8:00 AM to 5:00 PM and Saturday from 9:30 AM to 3:00 PM. Owners driving from Eastvale generally find the early morning drop off works best, since SR-91 westbound eases after the commute peak. Simple service items frequently complete in one to two days. Multi system work or anything waiting on a special order part runs longer, and the shop states which category a job is in before the vehicle is left. - Diagnosis appointment first, repair scheduled after parts are known - Same visit turnaround on many small electrical and plumbing items - Special order parts require a full deposit when the order is placed - Written authorization required before any repair proceeds - Final balance due at pickup before the vehicle leaves the property ## Frequently asked questions ### What is the difference between service and maintenance here? Maintenance is preventive work performed on a cadence, such as sealant inspection and resealing. Service is diagnostic and corrective work performed because a system is not operating correctly now. They often happen on the same visit, but they are scoped and billed differently, and the service side starts with reproducing and identifying the fault. ### Why do I have to pay for diagnosis? Because diagnosis is skilled labor, not a preliminary to a sale. Systematically isolating a fault on a twelve volt distribution system or a propane appliance takes time and test equipment. Diagnostic time bills at the posted $285 per hour with a one hour minimum, and that amount is credited against an authorized repair, so it is not paid twice. ### Can you service my generator? Yes. Generator service and repair covers run testing under load, fuel and carburetion issues, starting faults, output problems, control boards and routine service items. Generators that have been sitting unused account for a large share of the complaints. What is not performed here is engine rebuild work on the chassis powertrain, which is a separate category entirely. ### Do you offer pre purchase inspections on used RVs? Yes. The inspection runs the full house systematically and produces a written findings list separating current failures from developing issues and cosmetic wear. Buyers use it to negotiate or to walk away. The vehicle has to be brought to the Yorba Linda facility, since all evaluation happens in shop and there is no mobile inspection service. ### How quickly can I get a service appointment? It varies with season and current volume. Diagnostic appointments are generally easier to schedule than repair slots because they are shorter.
