How Often Should I Schedule Generator Maintenance?
If your generator struggles to start or has a lingering warning light, it’s advisable to call Corley Pro for a generator tune-up before the next outage. Homeowners should also listen for unusual noises and be alert to fuel odors near the tank. Along with slow startups and dashboard warnings, these can indicate that electrical inspections and maintenance are overdue.
Most whole-house generator systems need attention at least once per year. If the generator runs frequently due to repeated outages or seasonal storms, bi-annual care can help prevent strain and improve reliability.
Corley Pro can help prevent minor issues from becoming disruptions by providing timely standby generator maintenance in Greenville tailored to the system’s run frequency. Greenville often experiences strong spring thunderstorms and winter cold snaps, so planning a maintenance visit before peak seasons is a good idea.

- Increased reliability during storms or outages
