Furnaces will eventually have problems and their life-expectancy will run short. When this happens, you have two choices: (i) repair the furnace or (ii) buy a new one. With a used car, you get the chance to look under the hood, kick the tires and to test drive the vehicle. You know you likely will be spending at least several thousand dollars, so you want to do your research.

How Much Does a New Gas Furnace Cost?

For about what you will spend on a used car, you can buy a new gas furnace, but you do not get the same chance to test it out. How much will you pay

Typical Prices

For Phoenix and other large markets, gas furnaces are in great demand. They are extremely efficient, generally easy to service and amazingly reliable. This means you can expect to pay a market price that balances local demand with keen competition. 

The experts at Cost Owl point out the many factors affecting the final price for new gas furnaces and installation: 

If replacing an old unit, your home can keep most of its ductwork with minimal new runs, so expect to pay between $2,000 and $4,000 for a mid-efficiency gas furnace, installed, or $3,000 to $6,000 for a high-efficiency system.

If running new ductwork or installing in new construction, expect to pay $10,000 to $15,000.

Each additional heating zone could add between $1,000 and $2,000.

Numerous options, such as a Wi-Fi programmable thermostat, air purifier or deep-media air filter, will add to the cost. Modifications to existing chimney work may be necessary for the highest Annual Fuel Utilization Efficiency (AFUE) gas furnaces. 


The wise advisers at Consumer Reports caution against going with a rock-bottom price for a gas furnace. Efficiency matters, they say, because you will compound your energy savings the more years your new furnace is in service.

Compare purchase and installation costs of a 90 percent AFUE gas furnace against a 97 percent AFUE unit; you will generally find you save money over the life of the unit. 

Energy Star

Arizona is in the “southern tier” of states for the federal Energy Star program. This means our Phoenix gas furnaces must be at least 90 percent efficient by AFUE; the higher the AFUE, the pricier the purchase, but the more you will save in energy costs.
