Our Commitment
Our Commitment to Reliable Backup Power
At Grasten, our mission is simple: protect Texas families with reliable, expertly installed backup power. A standby generator sits idle most of the year, then has to start the moment the grid fails. That takes regular testing, fresh oil and filters, and a technician who knows the unit. Our team handles all of it, before and after the install.
The Turnkey Process
Our complete process covers every detail, including free estimates, personalized site visits, necessary permitting, expert installation, utility coordination, final inspections, and long-term service.
Ready for Emergencies
We keep a large inventory of generator repair parts in our warehouse and run a specialized fleet of service vans, and a real person answers our phones 24/7.
Warranty Protection
Every Generac air-cooled install carries the 12-Year Power Plus Warranty, and annual maintenance by our team keeps that coverage active for the long term.

Exclusive Power Plus Warranty 12 Years of Full Coverage
Twelve years of coverage on Generac air-cooled units. Labor, travel, parts, and major components are included at no extra cost, a $1,499 value exclusive to Canter Power Systems brands.
