My wife and I are going to replace our furnace that is located in a hallway closet on the second floor of our home. We are looking at the Amana AMVC8 furnace and the Lennox SL280V furnace. Both are variable speed. Our concern is which one would produce the least amount noise. Our installer says they are both quiet, but we have read that the Amana is pretty loud and my wife doesn't want a noisy furnace. We were just trying to figure out if that was accurate, because there is a price difference among the two.
