I am presently doing the search for a Furnace/AC or Heat pump and have had a Goodman and an Amana proposed to me. I have read through the forum and there are slight differences between the units and warranty's yet it seems most people seem to be wary of Goodman while having generally positive comments about Amana. Does the Goodman equipment come off the same assembly line as the Amana equipment? So aside from some differences in parts, Amana/Goodman should essentially be pretty similar units. Would I be right in my assumption? Assuming I get a great install, should I purchase Amana rather than Goodman equipment and pay the price.
