# Annual Maintenance Service: Cost, Hours and Process in Hacienda Heights

Annual maintenance service is a scheduled multi point service and inspection on a working coach: seals and sealant, appliance service, battery and charging check, water system, LP leak test, detectors, slide and awning operation, tires and running gear condition. It ends in a written report with a priority order rather than a verbal all clear.

## Specifications

- Price band: $400 to $2,500
- Shop hours: 3 to 10 hours
- Turnaround tier: Light cosmetic
- Insurance billable: no
- Parts lead time: Filters, anodes, sealant and detectors in stock, appliance parts 5 to 15 business days
- OEM brands: Lippert, Dometic, Suburban, Onan, Carefree, Thetford

## What actually gets done, and why the order matters

The service starts on the roof because that is where the money is. Every penetration gets inspected and the sealant condition recorded, and the deck is read for moisture on a grid against a dry baseline on the same coach. That single step is the difference between a $600 reseal and a $12,000 subfloor job two years later, and it is the reason we do not treat annual service as a checklist to be rushed.

From there it works inward. LP gets a pressure and leak test, which is certification gated work and is performed by a certified technician. Appliances get serviced rather than just switched on: the water heater anode is checked and replaced, the absorption refrigerator burner and flue are cleaned, the furnace is inspected and the air conditioner filters and coil are cleaned. Batteries get a load test rather than a voltage reading, because a voltage reading on a tired battery tells you nothing useful.

Then the mechanical items that move: slides cycled and seals inspected, awnings run and the fabric and arms inspected, levelling jacks cycled, entry steps cycled, and door and compartment latches adjusted. Tires get inspected for condition, pressure and date code, because RV tires age out long before they wear out and the failure mode is a sidewall letting go at highway speed.

## Why a coach that sits needs this more, not less

The most common thing owners say when they book is that the coach barely gets used, so surely it needs less attention. The opposite is true, and this region makes it worse. A coach parked in the open in the San Gabriel Valley takes a UV load that chalks sealant in three to four years rather than the six to eight the manufacturer assumes. Nothing about parking it protects it.

Sitting causes its own failures. Tires flat spot and the sidewalls degrade from ozone and UV whether they roll or not. Water sits in a tank and grows biofilm. An absorption refrigerator that never runs develops a cold shorted cooling unit. Batteries sulfate. Slide seals take a set and stop sealing. Rodents find the wiring. Every one of those is cheaper to prevent than to repair.

So the honest recommendation is annual service regardless of use, with the seal and moisture portion done every six months on a coach stored uncovered. That is the interval this climate actually calls for, not the interval a manual written in Indiana assumes.

## What it costs, and what happens when we find something

The band on this page covers the service itself: 3 to 10 hours depending on coach length, number of slides and appliance count, at the posted mechanical and electrical rate of $260 per hour, with a $45 hazmat and disposal fee where LP or refrigerant is involved. Parts consumed during the service, such as an anode rod, filters or detectors, follow the posted parts policy.

When the service finds something, you get it in writing with photographs and a priority order, plus a quoted price for each item as its own job. Nothing gets repaired without your authorization, and nothing gets folded silently into the service line. On a first visit to a coach older than about eight years, expect the report to contain several items. That is not a sales tactic, it is what an unserviced coach looks like.

Systems that turn out to be failed rather than merely due are diagnosed on the systems side of the shop, at the diagnostic rate of one hour at $285 credited against an authorized repair. Maintenance finds it. Repair fixes it. Keeping the two separately priced is what lets you trust the report.

## Not included

- We do not perform annual service at a customer location. Roof access, LP testing and undercoach inspection all need the bay.
- Engine, transmission and drivetrain service are outside what this facility performs. Coach systems and body are.
- Repairs the service finds are quoted separately rather than absorbed. You authorize each one on its own.

## Questions

**What is included in an annual RV service?**

A roof and seal survey with a moisture grid read, an LP pressure and leak test by a certified technician, appliance service including the water heater anode and the absorption refrigerator burner and flue, a battery load test, a water system check, slides, awnings, jacks and steps cycled with seals inspected, tire condition and date codes, and detector testing. It ends in a written report with a priority order.

**How often should an RV be serviced in Southern California?**

Annually for the full service, and every six months for the seal and moisture portion if the coach is stored uncovered. The UV load in the San Gabriel Valley chalks roof sealant in three to four years rather than the six to eight a manufacturer manual assumes, so the interval that matters here is shorter than the one printed in the book.

**My coach barely gets used. Can I skip it?**

A coach that sits needs this more, not less. Tires age out from UV and ozone whether they roll or not, water in a tank grows biofilm, an absorption refrigerator that never runs can cold short its cooling unit, batteries sulfate, slide seals take a set, and rodents find wiring. Storage prevents wear and causes a completely different list of failures.

**What happens if the service finds a problem?**

You get it in writing with photographs, a priority order and a separate quoted price for each item. Nothing is repaired without your authorization and nothing is folded into the service line. Anything that has actually failed rather than come due moves to the systems side of the shop and is diagnosed at one hour at $285, credited against an authorized repair.

**Do you service the engine and chassis as well?**

No. Engine, transmission and drivetrain service are outside what this facility performs, and we will tell you plainly rather than take the work and subcontract it. What we cover is the coach: body, roof, seals, slides, awnings, interior, and the onboard electrical, water, LP, heating, cooling and generator systems.
