I usually have Goettl come in the spring to service my heat pump. The service man surprised me by saying it had been up there for thirteen years, while I thought it was only about seven. It has proved very faithful. While the gentleman was here, I asked him to change the thermostat. After he left, I found the thermostat very complicated, not being familiar with the digital age. So after a few weeks I called them with the problem and they came back and put on a new one. He happened to be in the area so I got service within one hour. He was courteous and helped walk me through how to use it, and I found it quite simple. My experience with Goettl has been very good overall, and I plan on continuing to use them in the future.
