Goodman for years on their furnaces used a gas valve called a smart valve was junk every year they made a new and improved one till they finally got on board and went direct ignition like everybody else, lot of call backs on that, majority won't have prob just a numbers thing when looking as buisness decision what you want to install see more of the smaller companies single contractor type use more or cookie cutter housing where every penny is pinched, goodman also had a 10 yr warranty for a while not sure if still do which was awesome but they needed it,no a lot people who like goodman, my buddy started his own HVAC biz and started out with goodman had warned him, but like you said price matters but after his first year of nuisance callbacks he lost what he was making with the cheaper unit, now he doesn't use goodman unless customer demands it.
