HVAC replacement cost calculator

Direct answer: choose the actual replacement project first. Central AC, furnace, heat pump and combined AC + furnace replacements are different jobs, so one generic HVAC average is a weak starting point.

What this calculator is: a broad national budgeting tool. It does not size equipment or know your local labor, duct, electrical or permit requirements.

Model contract

The v1 model uses broad U.S. project-type bands and exposes its assumptions rather than presenting one universal HVAC average. The planning midpoint is a HomeQuoteCheck modeling value, not a contractor quote.
