Planning ranges, not quotes. Your project's access, condition and local code can move the number.
What changes the price
Cost depends on furnace type (gas, electric, oil, high-efficiency condensing), BTU capacity, venting, ductwork condition, thermostat and code upgrades such as combustion air.
- Ductwork changes — +$2,000 – $6,000 per number of furnaces
- Venting / chimney work — +$500 – $2,000 per number of furnaces
