What drives the price
Cost depends on system size (tons), SEER2 efficiency, refrigerant type, line-set and electrical condition, ductwork changes, and whether the furnace or air handler is replaced at the same time.

FAQ
How much does AC replacement cost?
A central AC-only replacement runs $3,500–$8,500 installed; a full system with ductwork is $9,000–$20,000.
How long does installation take?
A like-for-like replacement is usually one day; duct or electrical changes add time.
Should I replace the furnace too?
If it is old or the air handler is failing, replacing both together often saves labor later.
