Reviews
What customers say
Several customers praise the technicians' professionalism and clear explanations. One customer appreciated a tidy furnace-and-air-conditioner installation and a walkthrough of the new thermostat. A different customer reports that a heating issue in a furnace with a 10-year parts-and-labor warranty was said not to be covered.
