I had Chris Gwin install 220v with a 50amp GFI breaker for my hot tub. He charged me almost $800 for the install only for the 50amp GFI breaker to fail less than 2 years later. After calling him for 2 weeks with no response, he finally got back to me. He concluded the problem was with the hot tub without a proper diagnosis. After I challenged him, it turned out the breaker he'd installed was bad. Not the hot tub. He installed another one, a used one which gave out less than 2 weeks later. I would never recommend Chris. He ignores your calls, does shotty work and is big on using old parts and charging full price. Home owner beware.
