I have been very satisfied with Alpine Climate Control. They had an employee who did me wrong. I was very unhappy, but I understand he is now in Texas. It was a shock to me because he used to be a friend. He took my good thermostat and installed a faulty one. I have not been able to get as good of a thermostat because they do not make them anymore. I have never had that happen to me before. They have done work since then. They are very nice and do good work.
