Generator Maintenance in Myrtle Beach, SC
A professional service visit once a year is standard, on top of the brief weekly self-test most standby units run automatically. Oil and filter changes typically happen every 100 to 200 hours of runtime or once a year, whichever comes first.
Standard scheduling runs during regular business hours. Ahead-of-storm-season demand books out early — see the hurricane prep guide for timing.
How often does a standby generator actually need service?
The weekly self-test catches some problems (a battery going weak, a fault code) but not everything. Annual service is what catches the rest, before the unit is asked to run for real.
Skip it and…
What Happens If a Generator Never Gets Maintained?
It sits there looking fine and then doesn't start the one time it matters. That's the actual failure mode, not a dramatic breakdown while it's running.
A unit that hasn't been serviced since it was installed three hurricane seasons ago commonly has a weak or dead battery, stale fuel in a system that sits unused most of the year, or a transfer switch that's never actually been tested under real load. Every one of those is cheap and routine to catch during a service visit, and expensive and stressful to discover during an actual outage.
Maintenance isn't really about the generator failing gracefully. It's about making sure the machine you paid $9,000-plus for is actually going to work the one week a year you need it to.
One honest caveat: if your unit already sees real runtime from frequent outages and you're comfortable doing the oil and filter change yourself with a maintenance log, a single spring service call covers most of what an annual plan buys. The plan's real value is the battery load test and transfer-switch test under simulated load, which most homeowners can't safely do themselves.
What you get
What's Included in a Maintenance Visit?
- Oil and filter changeStandard on most annual visits, sooner if the unit has logged significant run hours from extended outages.
- Battery load testConfirms the starting battery can actually hold a charge under load, not just that it reads a voltage.
- Exercise-cycle checkConfirms the generator's automatic weekly self-test is actually running and completing correctly.
- Transfer switch testA simulated outage to confirm the switch still transfers load correctly, not just that the generator starts.
- Air filter and spark plug or glow plug inspectionWear items that affect starting reliability and run smoothness over time.
- Remote monitoring review, where equippedFor units with cellular or Wi-Fi monitoring, confirming alerts are actually reaching you, not just the app.
Step by step
How Does an Annual Plan Work?
Enroll and schedule
Time on site · a few minutesPick an annual plan or a single per-visit service; the plan gets you a scheduled visit rather than remembering to call.
Service visit
Time on site · 45-90 minutesOil, filter, battery, exercise cycle and transfer switch all checked and serviced as needed.
Written report
Time on site · same visitWhat was checked, what was serviced, and anything worth watching before the next visit.
Reminder before next season
Time on site · annualA scheduling nudge ahead of the next service window, so it doesn't quietly lapse a year and a half later.
A generator that's actually been tested under simulated load within the last year, not just sitting there looking maintained.

What Does a Maintenance Plan Cost?
| Item | Typical price |
|---|---|
| Single oil and filter service visit / per visitVaries with generator size and whether it's a straightforward visit or turns up an issue. | $50-$250 |
| Basic annual plan / per yearInspection, oil and filter change, battery check. | around $300 |
| Full-service annual plan / per yearAdds a full transfer-switch load test and fuel-system check to the basic plan. | $400-$600 |
| 10-year maintenance total, typical / over 10 yearsA useful budget line when comparing total cost of ownership, not just install price. | $2,000-$6,000 |
These are typical ranges for Grand Strand; your exact plan price depends on generator size and which plan tier you choose.
A repair discovered during a maintenance visit is quoted and authorized separately. It's not automatically included in the plan price.
Straight answers
How often does a standby generator need maintenance?
A professional service visit once a year, or every 100 to 200 hours of runtime if the unit has seen heavy use, on top of its automatic weekly self-test.
What's included in a generator maintenance visit?
Oil and filter change, a battery load test, an exercise-cycle check, a transfer switch load test, and an inspection of wear items like the air filter and spark plugs.
Does regular maintenance affect my warranty?
It usually protects it rather than affecting it negatively. Many manufacturers require documented maintenance as a warranty condition, and a missing service history is a common reason a claim gets denied.
Can you monitor my generator remotely?
If your unit has cellular or Wi-Fi monitoring built in, a maintenance visit includes confirming those alerts are actually reaching you. Not every generator model has this feature, and it's not something added after the fact.
How much does a maintenance plan cost per year?
A basic annual plan runs around $300; a full-service plan with a full transfer-switch load test runs $400 to $600 per year, depending on generator size.
