Goodman GMH95 gas furnace high (95%) efficiency Review

I agree the installation is key. Our contractor that installed our Goodman GMH95 assured us it would perform flawlessly if installed properly, and he was right. In five years, other than our annual scheduled maintenance, we have not had to call him out for any problems at all. The furnace heats our home efficiently and superbly comfortably. We couldn't be more pleased.

By the way, one of our neighbors had the same furnace installed by another contractor who was the lowest bidder. They had several issues with the furnace, and the installing contractor went out of business within a year. Turns out they weren't even licensed and never even obtained the required permit for the installation. The furnace wasn't installed correctly, which caused the problems in the first place. Well, the contractor WE hired corrected the installation mistakes the other company had made, and their furnace has worked just fine ever since.

Just goes to show you that the old cliche "you get what you pay for" is absolutely true!
