We recently purchased a new Carrie Infinity ultra high efficiency furnace from Dupont. Pat's in home consultation was excellent. He didn't try to sell us more than we needed and pointed out a few problem areas with our return ducting.
Mario and his team showed up on the Friday of a long weekend. They had to rip out the old furnace, do some duct work elsewhere in the house, install piping to our gas dryer, hook up a gas stove and install a new hot water heater. Most of the work was done in a very small space on a very hot day. They worked til 8pm. Mario then stayed and took another 45 minutes to explain how to use and maintain all the gas appliances. All this on a long weekend.
Well done Dupont. I wouldn't hesitate to recommend them.
