Generator Service questions
- How much does annual generator service cost?
- Copp Electric charges $350 for annual service on a standard air-cooled standby generator, including the 18-point inspection report, oil and filter change, air filter, and spark plugs.
- How often should a standby generator be serviced?
- Once a year at minimum, or every 100–200 run hours if the unit sees heavy outage duty. Annual service is also what keeps most manufacturer warranties valid.
