Yearly Service
Annual Generator Maintenance
Essential yearly maintenance to keep your generator ready and warranty-compliant
Your Generator's Annual Checkup
Most generator manufacturers require annual professional maintenance to maintain warranty coverage. Beyond warranty compliance, annual service is the minimum frequency to ensure reliable operation—catching wear items before they fail and verifying the system is ready for the next storm season. Buffalo Power Solutions recommends scheduling annual maintenance in spring, before Gulf Coast hurricane season begins.
