How these prices are built
Every price on this page comes from JobFlex's contractor price book: what a homeowner pays a licensed contractor for each step of the job, as a U.S. national average per unit, with the contractor's overhead and profit included and sales tax left out. The HVAC replacement is priced step by step, then multiplied by Fresno's construction cost index of 1.06.
Where the price book's steps for an option add up to more than 20% over the installed price a published source gives for the whole job, every step but a permit fee is scaled down to the middle of that range: central AC + gas furnace × 0.76 (HomeCostCalcs 2026: $7,000–$14,000); heat pump + air handler × 0.76, following central AC + gas furnace; cold-climate heat pump + air handler × 0.76, following central AC + gas furnace.
The index weighs local construction wages (BLS Occupational Employment and Wage Statistics, May 2025) at 60% and the area's material prices (Craftsman ZIP-area factors) at 40%. Published indices for Fresno, each on its own base: HUD 1.18, Craftsman 1.00. Treat any city figure as about ±5%; a contractor's quote for your house is the number to plan with.
