I need to replace my furnace. I want to put in the best and highest quality I
can because generally I find my highest cost is for labor and service visits, not for
the cost of the equipment.

Of the four brands listed, which one do you perceive as the best or top-of-the-line.
Once I select the brand, I will probably buy at mid-price range...i.e., not the
cheapest, not the most expensive.
