What Our Clients Say
Trusted by Facilities Across Northern California and Nevada
“I highly recommend PowerGen! A top notch generator service company that puts their customers first. Victor Poley is the owner and also works side by side with his technicians. There is no job that Victor will send his technicians on that he wouldn't do himself. Whether it be load banking, pulling cables, or annual service, he is side by side with his team.”
Bryan Thomas
“On time 24/7 service provided by experienced technicians. Superb service and advice, I highly recommend PowerGen for setting up a generator for your business. Victor and all the staff were great to work with. Our project was probably much smaller than what they are used to installing, but they gave our installation 100%.”
Mob Drippy
“I had a generator installed by PowerGen and I have to say that I'm truly impressed how professional the team has been. Quote was reasonable, install happened when it was promised and the staff was friendly and professional throughout the process.”
Peter Fröde
“We had some questions about our batteries in our backup generator — they installed the correct batteries. We are a small commercial truck yard with portable offices. We would recommend them to small and large companies alike. Great job PowerGen!”
Gary S.
“I would recommend their services to anyone who needs generator maintenance. Our facilities use them all the time.”
