How Much Does a New Furnace Cost in 2026?
September 2, 2026 3 min read
Most furnace pricing online quotes the equipment only, which is why the number never matches the one a contractor gives you at the kitchen table. Here is what a complete, professionally installed furnace replacement actually runs in 2026, and what pushes a project toward the high end of the range.
What a fully installed price includes
A furnace replacement is a project, not a product. The price you should be comparing covers the equipment plus everything required to put it into service in your home.
- The furnace itself, sized for your home
- Standard installation labor and basic materials
- Gas, electrical and venting connections at the unit
- Removal and disposal of your existing furnace
- Permit allowance where your city requires one
- Startup, safety checks and testing
Equipment is usually somewhere between a third and half of the total. The rest is labor, materials, code requirements and the specifics of your installation.
Typical installed price ranges in 2026
| Option | System | Estimated installed price |
|---|---|---|
| Good | 80% efficient, single-stage | $4,400 – $6,200 |
| Better | 96% high-efficiency, two-stage | $7,400 – $9,000 |
| Best | 96%+ variable-speed | $9,400 – $11,600 |
National mid-range bands for an average-size home. Your market can run meaningfully above or below these.
Where you live matters more than most homeowners expect. Labor in high-cost metros can run 20–30% above the national middle, while many parts of the Midwest and South land below it. A furnace in Boston, Seattle or the Bay Area is simply a more expensive project than the same furnace in Indianapolis.
What pushes the price up
- Switching from an 80% to a 96% furnace, which requires new PVC venting
- A tight attic or crawlspace installation instead of an open basement
- Undersized or deteriorated ductwork that has to be modified
- Gas line or electrical upgrades to meet current code
- Adding a new thermostat, humidifier, air cleaner or surge protection
- A larger home that needs higher-capacity equipment
Emergency replacement vs. planned replacement
A furnace that dies in January leaves you comparing one option under pressure. Homeowners who shop before the failure tend to land better: more time to compare, more equipment availability, and room to use financing or off-season promotions instead of taking whatever can be installed tomorrow.
How to use a price range
A good estimate gives you a shopping target, not a contract. It tells you whether a quote you receive is normal, high or suspiciously low. Final pricing still depends on a professional confirming sizing, venting and the condition of what is already in your home.
Ranges are estimated fully installed prices — furnace, standard installation labor, basic materials, removal of the old furnace, startup and testing. Local labor rates, venting and any required updates move the final number.
