My furnace was nut working and within an hour Dupont had a technician to my house. It was dead. Within a very short time I had a quote for a new furnace and by noon the next day the furnace was installed! I had to put in a high efficiency so the had to find a way to vent it directly to the outside. My basement is all finished. They managed to find a way with just a small cut in the drywall. Amazing service and a neat and careful installation. I have used Dupont many times in the past and highly
