After reading the posts on this forum, I have discovered that Bryant and Carrier are the same company. I was looking at the Infinity furnace/AC combo. I understand that the Bryant Evolution is the same as the Carrier Infinity. With all variables being the same with regards to installation,warranty,etc...Is there that much of a difference in purchase price between the 2 systems? I know we cant talk about exact prices but a general ballpark % would be helpful if there is a significant difference?
