The gentlemen from SUNDANCE Energy Services were respectful, quick and professional. They came in, gave an estimate, and thought the work would take two days--but it only took one. They put in a heat pump, a furnace, and an air conditioning unit; the cost seemed fair, but we didn't compare because we've worked with them before and they've always treated us fairly. They have also put in a gas fireplace, replaced a water heater, and replaced a furnace about eight years ago. We had our furnace go out during the winter, and they came out right away on the same day with no problem.
