The decision this library answers
Begin with the whole-system replacement guide if you do not yet know the final configuration. Move to the equipment-specific guide only after you know whether the project is central AC, a furnace, a heat pump, or ductless. Use the calculator as a planning screen, then replace its assumptions with two or three written local scopes.

The ranges are not live contractor prices. Local labor, access, permits, equipment availability, code work, financing, and concealed conditions can move a real bid outside them.
