For this project we publish the measured range only. We add a calculator once the permits record enough detail (size, type) to support a formula.

Nearest cities with permit data

We have no permits from Delaware yet, and our state adjustment is not accurate enough for this project (error above 10% in our tests), so we do not publish a Delaware figure. Above is the range across the cities we measure; below, the closest ones.

What changes the price

Location

the median ranged from $5,000 in Dallas, TX to $7,281 in New Orleans, LA.

Project scope

the high end of the range is more than double the low end, so size, access, tear-off of old material and finish level matter as much as location.

Questions

How much does a furnace replacement cost?

The typical (median) cost is $6,141. Half of projects fall between $3,400 and $8,257, based on 76 building permits in Dallas, TX and New Orleans, LA.

Where do these numbers come from?

From building permits that U.S. cities publish on their open-data portals. Each permit includes the project cost declared by the applicant. We filter residential projects of this type and report the 25th percentile, median and 75th percentile.

Why might my quote be higher than these figures?

Permit applicants declare the cost themselves and some understate it. Permits also exclude work that does not need one. Treat the high figure as a realistic ceiling for an average project, not a maximum.
