My furnace blower motor has just gone on my Tappan 120,000 BTU HVAC furnace, the unit was installed in the 70s and over the past year I have had issues with the temp of the air at the ducts and circulation to the second floor. We had a contractor in to price a new Trane unit through the Home Depot program. What is the pricing one should expect with this type installation? Would I be better off just replacing the blower motor?

Thanks for your assistance.
