AC Replacement cost breakdown
At a mid-range, national-average baseline, a typical ac replacement project is estimated at $4,000 to $9,000. The table below breaks the cost down so you can see where your project is likely to land.
| System type | Typical installed cost | Notes |
|---|---|---|
| Central AC (standard) | $4,000 to $7,500 | Most common |
| High-efficiency | $7,000 to $12,000 | High SEER2 |
| Heat pump | $6,000 to $14,000 | Heats and cools |
What drives ac replacement cost
- System size (tons) for the home.
- Efficiency rating (SEER2).
- Standard AC versus heat pump.
- Like-for-like versus ductwork or capacity changes.
- Regional labor rates and refrigerant.
Key cost factors
Sizing matters
An AC sized correctly to the home (via a load calculation) runs efficiently and lasts longer. Oversized or undersized units waste energy and wear out faster.
Efficiency
A higher SEER2 rating costs more upfront but lowers cooling bills, which pays off most in hot climates with long cooling seasons.
