Answers to Common Questions
View All FAQsWhat are the top reasons a Generac generator won't start?
Most no-start calls we see trace to overdue maintenance or transfer-switch/panel integration issues. Routine service—oil changes, filter replacements, and inspections—often restores reliable starts. We install and service whole-home systems, so our electricians can verify ATS operation and the generator’s integration with your electrical panel in Roanoke and Rocky Mount.
Quick checks:
- Note when the last oil and filter service was performed.
- Do not attempt panel or ATS work yourself; schedule a professional inspection.
- Ask about financing if repairs or replacement are needed.

Change the oil per your generator manufacturer’s schedule, which is based on run hours and time in service. We include oil changes, filter replacements, and inspections in routine generator maintenance. If your generator ran for many hours during a storm or outage, schedule service soon. Our licensed team services whole-home generators in Roanoke and Martinsville and can advise the right interval for your model. Diamond Club members receive priority service and one annual electrical inspection.

There isn’t a one-size price for standby generator repair. Wisler provides free quotes in the Roanoke area, and final cost depends on the diagnosis, parts, and labor. Repairs can range from simple maintenance items to fixes involving the automatic transfer switch or panel tie-ins. A technician will assess your whole-home system and confirm pricing on site. Licensed electricians perform the work and back it with our 100% satisfaction guarantee.
Quick factors that affect cost:
- Issue severity and parts needed (oil, filters, battery, ATS components)
- Generator size and accessibility

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.
