Frequently Asked Questions
How much does generator repair or maintenance cost in San Antonio?
A standby generator tune-up typically runs about $150 to $500 and covers oil, filter, spark plugs, a battery check, and a load test. Repairs vary: a battery is roughly $100 to $300 and a control board can run $500 to $1,500. C.S.W. diagnoses the unit and quotes the repair before any work.
Why won't my standby generator start?
The most common causes are a weak or dead battery, a tripped or failed controller, low oil or a sensor fault, a closed fuel valve or low gas pressure, or a unit that has missed its exercise cycle and maintenance. C.S.W. tests the battery, controller, fuel, and transfer switch to find the actual fault.
How often does a Generac standby generator need maintenance?
Plan on annual service plus a load test, with oil and filter changes on the manufacturer's schedule. San Antonio's heat and dust make the air filter and battery worth checking before summer storm season. Annual service plans typically run about $300 to $600.
Do you service generators you did not install?
Yes. C.S.W. repairs and maintains standby generators from major brands regardless of who installed them, including diagnostics, battery and transfer-switch service, load testing, and repair-versus-replacement guidance. Call 210-504-9796.
