Furnace Replacement cost breakdown
At a mid-range, national-average baseline, a typical furnace replacement project is estimated at $3,000 to $8,000. The table below breaks the cost down so you can see where your project is likely to land.
| Furnace type | Typical installed cost | Notes |
|---|---|---|
| Electric | $2,000 to $5,000 | Lower upfront |
| Gas (mid-efficiency) | $3,000 to $7,000 | Most common |
| Gas (high-efficiency) | $5,000 to $10,000 | 90%+ AFUE |
| Oil | $4,000 to $9,000 | Where gas is unavailable |
What drives furnace replacement cost
- Furnace type: electric, gas, or oil.
- Efficiency rating (AFUE).
- Furnace size for the home.
- Like-for-like versus new ducts or fuel conversion.
- Regional labor rates and permits.
Key cost factors
Efficiency pays back
A high-efficiency (90%+ AFUE) furnace costs more upfront but lowers heating bills, which matters most in cold climates with long heating seasons.
Swap vs ductwork
Replacing a furnace with the same type is the cheapest. Adding or replacing ductwork, or converting fuel types, raises the cost significantly.
