Can I service my standby generator myself safely and effectively?
You can handle basic upkeep, but safe, effective standby generator service is best left to a licensed technician. Regular oil changes, filter replacements, and inspections keep performance strong. With proper maintenance, many home generators last 8–10 years, and some reach 15–20 years. Because whole‑home systems tie into your electrical panel and an automatic transfer switch, a pro should perform repairs and adjustments. We install, service, and repair generators with 24/7 support in Roanoke and nearby areas.
