We bought and had installed a 7 kw standby generator through Canter. I shopped other companies, but only Canter provided "soup to nuts" service. They pulled the permits, they contacted my natural gas provider and made the appointments for connection, they made sure the inspections happened. I didn't have to do a thing but show up when they needed to get into my garage. Purely professional, they left my yard clean and in good condition. The only reason I didn't give them a 5 on price is because buying a standby generator is expensive, but that's not their fault really. Speaking of expensive, I found that the other companies I called were not interested in my business because I wanted a small generator, just enough to power the necessities. Canter never batted an eye and worked with me to make sure I got power to exactly what I wanted. I wish all companies worked as well as Canter.
