HVAC replacement cost in California

What citable sources say about an HVAC replacement in California — named cost estimates, rebate programs, and the honest gaps. 4 of 5 rows below carry a machine-verified quote; the rest say so plainly. Last checked 2026-09-05.

How to read this page: no one publishes a citable California-specific price for an HVAC replacement — sites that show one anyway are estimating. This page shows named national estimates (labeled, with fetch dates), official program figures (quoted verbatim), and says “get local quotes” where no citable figure exists. It is not an estimate of your project.

Permits & local fees
no citable figure — get local quotes		Permits for an HVAC replacement are issued by your city or county in California, and permit fees are set locally — there is no single statewide fee, and no official statewide fee schedule was machine-fetchable on build day. This site publishes none: ask your local building department, and get permit costs included in written local quotes.
Talking to local contractors is how a real price gets made. (Partner placement reserved; text only for now — this site names no contractors and no lead networks.)
