Depending on the size of your home, the efficiency of your new furnace, and the sophistication of the equipment, a new furnace replacement can cost anywhere from $3,000 to $7,600. Not just equipment costs, but also labor costs and permit fees are included.
The above range includes smaller residences as well as residences larger than 5,000 square feet. One-stage, two-stage, and variable-speed furnaces are also included, as are each of those types in both basic and high-efficiency models.
