I have had my HydroHot serviced at Lee-Smith in Chattanooga, where I have all of my work done. Their work has always been satisfactory. However, when I can, I try to have the work done at one of the big rallies where a full-time AquaHot tech, such as Orman Claxton, can do it, just because they have more experience than the techs at a general purpose shop.
