I'm glad to have find such a great site. It seems to be a wealth of info.
I am in the process of changing a 30+ years forced air furnace. I have several quotes. I was thinking of going with the suggested G61 from Lennox. However, there seems to be a lot of problems with the lennox brand. can any one shed some much needed light on this matter. By the way, I want to go with a high efficiency furnace. I was only quoted for the lennox, not the Trane, even though
that dealer carriers both Trane and Lennox furnaces. Should that raise a red flag?
