The Industry's Only 12-Year Full Coverage Warranty, a $1,499 Value Included with Your Purchase
Every Generac air-cooled system Grasten installs is covered for labor, travel, parts and major components, exclusive to Canter Power Systems brands.
Why It Matters
Why Reliable Generator Warranty Service Matters
A whole-home generator is a significant investment in your family’s safety and comfort. Without warranty coverage and expert service, a single major component failure can cost thousands of dollars. An active warranty backed by Grasten’s certified service team keeps surprise repair bills off your plate and your system healthy for its full life.
Coverage
Our Exclusive Generator Protection and Coverage
Grasten is a Generac Prestige Dealer, and the Power Plus Warranty runs for 12 years, while standard manufacturer coverage steps down after two years and ends at five.
The Difference
Why Our 12-Year Warranty Is a Game-Changer
As a Generac Prestige Dealer, the highest level of Generac dealer recognition, Grasten can offer coverage most installers can't. The 12-Year Power Plus Warranty gives Texas homeowners:
Twelve Years, No Step-Downs
Generac's standard warranty covers everything for only 2 years, then drops to limited parts and major components. Labor coverage ends after year 2, a big repair cost driver. Our warranty? Labor, travel, parts, and major components for all 12 years. No step-downs.
Transferable for Added Value
Selling your home? Transfer the remaining coverage for a small fee and give buyers confidence, with a full system orientation so they know how the generator runs.
Serviced by the Team That Installed It
No third parties, no delays. The same Grasten team that installed your generator maintains it, so nobody starts from scratch when something needs work.
No Claim Forms, No Waiting
This is our warranty, not a third-party plan. No red tape, no return visits. If the part is on our service vehicle, we fix it immediately.
