After doing lots of research on Geothermal systems and reading glowing reviews, we decided to go with Sinton, and it worked out just beautifully. Bill Sinton is not only the owner, but is totally involved in the whole installation all the way through, and his sons Jamie and Matt are fully trained in the entire process. This is such a pleasure after experiencing companies that send their "sell" man out to sell you and then you never see him again - and who knows who the actual workers are. No - Sinton is a total family process, with his intelligent young sons doing the entire job, accountably, neatly, and with integrity. But most importantly for us, when Bill discovered that our existing heating system was lacking important return ducting, they showed us why our heat never felt right, and proposed a big job that was not a happy moment to hear about, but it was the RIGHT thing to do. Bill explained that finally our upstairs and downstairs would be the same level temperature - we didn't think that was possible. They basically redid the entire system, and we now finally have a house that feels uniformly warm and comfortable, and the benefit of being off fossil fuels!!! Also, they always returned our calls immediately, from Mallory (the daughter) in the office, to Bill, to his sons who were always available and let us know exactly what the schedule was and Stuck to It! We are so grateful to have found people who are smart enough to understand what is needed, skilled and responsible enough to do it properly, and nice enough to explain it all to us. We cannot give a high enough recommendation to Bill Sinton and his family business.
