Gas Furnace Explained

A gas furnace is a heating system that uses natural gas or propane as a fuel source to generate heat for residential or commercial spaces. It operates by burning gas in a combustion chamber, where the heat produced warms a heat exchanger. Air is then circulated over the heat exchanger by a blower, distributing warm air through ductwork to various rooms. Modern gas furnaces are highly efficient, often achieving Annual Fuel Utilization Efficiency (AFUE) ratings of 90% or higher, meaning most of the fuel is converted into usable heat.

How much is a Gas Furnace?

The cost of a gas furnace for a 2,000-square-foot home, including installation, typically ranges from $3,000 to $10,000, with an average of about $6,000. This includes the furnace unit, priced between $800 and $3,500, and installation labor, which adds $1,000 to $3,000. High-efficiency models (90%+ AFUE) cost more upfront, averaging $2,000 to $6,000 for the unit alone, but can save on energy bills. For a 2,000 sq. ft. home, you’ll likely need a furnace with 60,000 to 100,000 BTUs, depending on your climate zone, insulation, and home layout.

Key factors affecting cost:

  • Furnace efficiency: Standard (80% AFUE) is cheaper than high-efficiency (90%+ AFUE).
  • Brand: Goodman is less expensive ($600–$3,200), while Bryant or Lennox can range from $800 to $7,500.
  • Climate: Colder regions (e.g., Wisconsin) require higher BTUs (50–60 per sq. ft.), increasing costs, while warmer areas (e.g., Texas) need fewer (30–40 BTUs per sq. ft.).
  • Ductwork: New ductwork adds $2,400–$6,600; repairs or cleaning cost $200–$1,000.
  • Additional work: Gas line installation ($500–$2,000) or asbestos testing ($250–$850) for older homes may apply.
