Typical cost ranges
These are installed-cost planning ranges for the options modelled by the calculator.
| Option | Typical range |
|---|---|
| Central AC only | $3,500 – $8,500 |
| Heat pump | $5,500 – $15,000 |
| Ductless mini-split | $3,000 – $8,000 |
| Full system + ductwork | $9,000 – $20,000 |
Planning ranges, not quotes. Your project's access, condition and local code can move the number.
What changes 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.
- Line set / electrical update — +$500 – $1,500 per number of systems
- New thermostat — +$200 – $600 per number of systems
State differences

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.
