    Dupont Heating was terrible service. This guy Mario installed my Furnace 12 years ago. Within weeks it kept breaking down. He kept charging each time and rude about it. I called Carrier and it was the incorrect furnace! I called Dupont recently and unfortunately Mario showed up again. He charged me $200 for looking at it for only a few minutes then said it would cost over $1000 to fix it. Another company fixed it for $350
