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.
