WHAT our satistied customers have to say
I came away with the impression that he is exceedingly competent, and he explained various aspects of the unit and what he was checking for and doing to it as he went along, which I appreciated. If his repairs are anything like his maintenance check ups, I doubt if you can find a much better technician for the money. I highly recommend him!
