How this ranking is calculated
BuildCost models hvac replacement pricing across five U.S. regions (Northeast, Southeast, Midwest, Southwest, West). Each state is ranked by its region's labor and material costs, so states in the same region share a baseline — actual prices still vary by metro, contractor, and site conditions. Totals assume a typical 1 systems project at mid-grade materials. For a precise local figure, open your state's page or run the free estimate tool.
