Review:
"FURNACE"
I purchased a Goodman gms8 gas furnace in January 2005 and it ran good. Until 2 years later, we had to replace a major part which my husband hired/paid a repairman for but we never got to keep the replaced part to see if it was warrantied (which is another matter I am not happy about). The following year in 2008, another problem and then again this winter, we've had a repairman come out twice which he told us we eventually will need a certain part that my husband was able to order online and install himself which saved us a bundle. We are hoping we won't have further problems. My daughter is looking for a new furnace and I don't think I will recommend Goodman.
