My hot tub panel would fault and stop heating. It appeared re-setting the breaker would fix this problem, but the panel would fault again at any given time. I called Bernie just before I was flying to Vancouver, It was -32 and my hot tub was at 67 degrees. He showed up and baby sat the hot tub to troubleshoot the panel. We replaced the Spa Pack and it has worked great since. No complaints from his service. He prevented my tub from freezing.
