Questions
How much does an hvac replacement cost in San Francisco?
The typical (median) cost is $19,534. Half of projects fall between $11,458 and $30,000, based on 24 building permits in San Francisco.
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.
