We are very happy with SUNDANCE Energy Services. They replaced our old gas furnace with an efficient furnace and installed an air conditioner. The sales person, Doug. was very knowledgeable and competent in the field, which I appreciated. I also liked that they had all the work done by the same group, so it was like one stop shopping and was efficiently done. The technicians who carried out the installation were professional and knew what they were doing. The installation happened without any issues. I'm happy with how everything has turned out so far.
