Why this site exists

Most people replace a furnace exactly once or twice in the time they own a house, usually because the old one already died. That is a bad moment to start learning what fair pricing looks like, especially with a repair van in the driveway and a house getting cold. FurnaceReplacementCost.net exists to put a defensible number in front of you before that first quote lands, so you can tell whether it is reasonable or padded.

The calculator on the homepage covers gas, electric, and oil furnaces from standard 80% AFUE single-stage units up through 96%-plus two-stage and variable-speed models. Equipment tier moves the price on its own, since a premium brand like Carrier, Lennox, or Trane installs at a real premium over a mid-tier option like Rheem or Goodman, and installation complexity does the rest: a straight swap of an existing forced-air system costs a lot less than a job that also needs new venting, a gas line relocation, or duct modifications. The ZIP code field exists because labor in a place like San Francisco or Boston runs meaningfully higher than labor in a smaller Midwest or Southern market, and a single national number would be wrong for both.

Where the numbers come from

The ranges behind the calculator are built from HVAC contractor pricing surveys, manufacturer list pricing, and published regional labor-rate data, then checked periodically against current market conditions. The editorial standards page has the full detail on sourcing and corrections. This site has no ownership stake in and takes no direction from any furnace manufacturer or HVAC contractor chain; the price ranges you see would look the same regardless of which brand or contractor ends up doing your install.

How the site makes money

Display ads run on this site, and the "Send me local quotes" buttons route to a partner network of HVAC contractors; if you submit a request through one of those buttons, we may earn a referral fee. Neither arrangement changes a single number in the calculator or the guides. Before you sign anything, get at least two itemized quotes from licensed HVAC contractors in your area and confirm local permit requirements with your municipality.
