AC replacement cost guide
AC replacement cost is driven by tonnage, indoor coil compatibility, duct condition, refrigerant lines, permit handling, and efficiency tier. A fair quote should explain both the outdoor condenser and the indoor components being replaced.
Direct answer
$2,650 - $5,650
Baseline estimate for a 2,000 sq ft home using central air before local labor, ductwork, permit, access, and verified incentive adjustments.
Rough install estimate — adjust square footage and system type.
Estimated install range
$2,650 – $5,650
4 Ton System Required · Climate zone 4 · Labor ×1.00
Adjust the home size or system type to review the estimate before comparing local quotes.
Repair-versus-replacement boundary
A capacitor, contactor, drain, thermostat, or isolated electrical fault is not the same job as replacing the condenser and indoor coil. Ask for the failed part, measurements, refrigerant findings, labor, warranty, and expected result. Compare replacement when the system has repeated major faults, an uneconomic compressor or coil failure, incompatible refrigerant or components, or unresolved airflow and duct problems.
| System | Range | Quote note |
|---|---|---|
| Central Air | $2,650 - $5,650 | Best for homes with usable ductwork and separate heating. |
| Heat Pump | $2,850 - $6,200 | Often costs more upfront, but can replace heating and cooling in one system. |
| Ductless Mini Split | $2,250 - $6,800 | Useful for additions, older homes without ducts, or zoned comfort. |
| Home size | Tonnage | Range |
|---|---|---|
| 1,200 sq ft | 2 tons | $2,300 - $4,900 |
| 1,600 sq ft | 3 tons | $2,500 - $5,300 |
| 2,000 sq ft | 4 tons | $2,650 - $5,650 |
| 2,400 sq ft | 5 tons | $2,800 - $6,050 |
| 3,000 sq ft | 5 tons | $2,800 - $6,050 |

Not always. AC replacement may cover only cooling equipment, while HVAC replacement can include heating equipment, air handler or furnace, controls, ducts, and broader code corrections.
Sometimes, but many quotes should include an indoor coil match and AHRI verification. Replacing only the outdoor unit can create performance or warranty issues if the system is mismatched.
Higher tonnage, variable-speed equipment, duct repairs, electrical corrections, hard access, and peak-season labor can all raise the quote.
Clear HVAC Costs models ac replacement cost with system type, estimated tonnage, home size, climate assumptions, and typical labor scope. Results are planning ranges only and should be checked against itemized local bids. Last updated October 7, 2026.
