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.

Standby generator repair cost varies by issue and is confirmed after an on-site diagnostic. Most costs come down to the parts that need replacement and the labor time to restore safe, reliable operation rather than simple maintenance. Our electricians work on many home generators in the Roanoke area and provide clear quotes before any repair begins.
Price can swing based on:
- Diagnostic time needed to trace the fault
- Components replaced (electrical controls, fuel-system parts, sensors, wiring)
- Generator size and system complexity
- Age, maintenance history, and whether the visit is urgent or scheduled
Free quotes are available for generator repair and installation. Schedule service promptly if your unit won’t start or trips off under load to avoid damage during an outage. <br/> Updated: 2026-04-02 <br/> Need help in Rocky Mount, VA? Call (540) 238-0320 or book online.

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

Home standby generator installation cost is custom to each home and finalized after an on-site assessment. The largest cost driver is the generator size required to support your essential circuits during an outage. We install and service generators throughout the Roanoke region with licensed, background-checked technicians. $500 off complete generator installation is currently offered; call to confirm eligibility and any restrictions.
Key factors that set the final price:
- Power capacity (kW) and whole-home vs. essential-circuit coverage
- Fuel source (natural gas or propane) and meter/tank readiness
- Transfer switch type and any electrical panel upgrades
- Site work, pad placement, trenching, and distance to utilities

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. <br/> Updated: 2025-12-21 <br/> Need help in Roanoke, VA? Call (540) 234-2001 or book online.
