If your furnace fails, you'll notice. Sometimes it's possible to repair your furnace, but eventually you may need to purchase a new unit. When installing a furnace becomes your best option, think about these important cost considerations before buying.
The first thing you'll need to consider is the type of furnace to install. Since most furnaces last between 15 and 20 years, chances are the choices now available didn't exist when your original unit was purchased.
The most common residential furnace is powered by natural gas. According to Bluebook International, which publishes residential repair and replacement costs, the cost of a standard efficiency natural gas furnace ranges from $2,250 to $3,800. You may incur higher costs, depending on the complexity of the install or if you choose a higher efficiency unit.
