We are getting quotes on a new HE (95%) furnace. One is a Lennox dealer the other sells Goodman. I have never heard of that brand . I did a google and found mixed reviews. Dealer extolls the tubular heat excanger and longer warranty. The dealer is a huge home supply store. Probably 150 employees. They have their own mechanical division and do install a lot of furnaces in this area. Any comments on the Goodman brand?? Thanks
