Central ducted heat pump (2-ton): the short answer
As configured, budget roughly $6,500 – $12,500 for a central ducted heat pump (2-ton), rising toward $8,500 – $17,500 once new ductwork and electrical work are included. Two tons is the small end of common whole-home sizes, so per-ton pricing makes it the least costly of the typical central ducted installs. Watch the ductwork, though: on a small system, adding or reworking ducts raises the total by proportionally more than it would on a larger one. The biggest swing is still your own site, so itemize your estimate above.
