Hell, you can find just about any other information on this board so I figure I would give this a try as well. I just got an estimate to put a new Furnace/AC unit in my house. The guy gave me 2 estimates. One for a Lennox unit and the other for a Goodman unit. As far as specs go they seem very similar but the Goodman unit is considerably less with only a 5 year warranty on the compressor as opposed to a 10 year warranty for the Lennox. I can upgrad to a 10 year comperessor for an extra $250 though. My question is have any of you hear of or had any experience with Goodman?
