How much does a gas furnace from the best brand cost?

As of 2015, prices for top-rated furnaces typically range between $950 and $1500 for the furnace itself, according to Furnace Compare. This does not include the cost of installation, which can substantially increase the overall cost of a furnace purchase.

Furnace installation costs generally add anywhere from $1000 to $10,000 to the overall cost of a furnace, depending on the specific model of furnace and the complexity of the installation. Installing new ducts in homes that do not have ventilation systems adequate for a new furnace can multiply installation costs by as much as 10 times the cost of the furnace itself.
