I've got a 7 yr old unit at the house and I am on my 3rd coil. It has been a POS from the first day it was installed. Goodman supplies the replacement coil each time but now I'm having pay for labor on the installs. I wouldn't put a Goodman in my black lab's doghouse. When I had all my problems, I started doing research and found that there was a class action lawsuit brought against them but it was dismissed because the judge ruled that not enough plantiffs were affected if I remember right. Only 2-3% of the units sold during that period of time were considered faulty and the judge dismissed the case. From what I remember reading on the dismissal, it seemed shady. Stay far far away from Goodman.
