New Furnace Cost in 2026: What the Equipment Costs and How to Choose It
Updated July 2026 · Reviewed by the United HVAC Motors technical team
New furnace cost at a glance (2026, installed)
- Typical range: $3,000 to $8,000
- Most homes land at: $4,500 to $6,500
- Equipment is only 40 to 60% of that. The rest is labor and scope.
This guide covers what the equipment costs and how to choose it. If you are deciding whether to repair or replace and how to read competing bids, see our furnace replacement guide.
Furnace pricing looks arbitrary until you see what is actually being priced. A furnace is not an appliance you drop in place — it is a component in an air distribution system, and most of the cost variation comes from what that system needs, not from the box itself.
Cost by Fuel Type
| Fuel | Installed Cost | Notes |
|---|---|---|
| Natural gas | $3,500 to $7,500 | Most common. Widest efficiency range, 80% to ~98% AFUE. |
| Electric | $2,000 to $5,000 | Cheapest to install, most expensive to run in cold climates. |
| Propane | $4,000 to $7,500 | Similar equipment to gas, higher fuel cost. |
| Oil | $5,500 to $10,000+ | Regional, mostly Northeast. Fuel storage and fewer contractors. |
Ranges reflect typical U.S. installed pricing as of mid-2026 and vary significantly by region and labor market.
What AFUE Actually Buys You
AFUE is the percentage of fuel energy that becomes usable heat. An 80% furnace sends a fifth of it up the flue; a 96% furnace sends 4%.
The dividing line is condensing technology. Above 90% AFUE, a furnace extracts so much heat from the exhaust that water vapor condenses out of it. That changes the whole installation:
- A secondary heat exchanger to capture that last heat
- PVC venting instead of metal flue, because the exhaust is cool and acidic
- A condensate drain, and often a pump
- Usually a variable-speed ECM blower, because the second exchanger adds airflow resistance
That is why the jump from 80% to 96% costs more than the equipment difference suggests. You are buying a different installation, not just a better box.
The high-efficiency trap. A 96% AFUE furnace fitted to an undersized duct system does not deliver 96% comfort. The secondary heat exchanger adds resistance to a system already fighting for air, the blower works harder, and you paid a premium for efficiency the ductwork will not let you collect. Ask for static pressure to be measured before you specify high-efficiency equipment — see what ideal static pressure is and why it matters.
Single-Stage, Two-Stage, or Variable-Speed?
- Single-stage. Full output whenever it runs. Cheapest, with the most temperature swing.
- Two-stage. Runs on low most of the time. Roughly $800 to $1,500 more, and noticeably more even.
- Variable-speed. Modulates continuously, with an ECM blower holding target airflow as conditions change. The best comfort and humidity control, and the highest price.
The caveat is the same one. A variable-speed system earns its premium by maintaining airflow against resistance. On a restricted duct system it spends that advantage fighting the ducts, drawing more current and running its control module hotter. Good ducts first, then the premium equipment.
Sizing: Bigger Is Not Better, and It Costs You Twice
Furnace capacity is rated in BTU. An oversized furnace short-cycles — it satisfies the thermostat fast, shuts off, and restarts constantly. That produces temperature swings, wastes fuel, stresses the heat exchanger, and puts the blower through far more start cycles than it was designed for.
Correct sizing comes from a Manual J load calculation, which accounts for square footage, insulation, window area and orientation, air infiltration, and climate zone.
Ask every bidder whether they performed one. A contractor sizing by square footage alone, or by matching whatever was there before, is guessing — and the previous unit may have been wrong too. This single question separates serious bids from the rest.
Where the Non-Equipment Money Goes
The furnace itself is often only 40 to 60% of the total. The rest:
- Labor — $1,000 to $3,000 depending on access and complexity
- Venting — new PVC runs for condensing equipment
- Gas line resizing — if BTU capacity increased
- Electrical — for ECM blowers and modern controls
- Duct modifications — $500 to $3,000, and the line most often missing from a cheap bid
- Permits and inspection — $50 to $300
- Condensate pump — for basement or attic installs without gravity drainage
- Removal and disposal — $100 to $300
Rebates and Tax Credits
High-efficiency furnaces have qualified for federal energy-efficiency tax credits and utility rebates in recent years, with eligibility generally tied to AFUE thresholds. These programs and their eligibility rules change, so verify current status with the program administrator or your tax advisor before budgeting around one. Utility rebates are typically easier to confirm and are administered locally.
Operating Cost: The Line Nobody Compares
Two furnaces with the same AFUE can cost different amounts to run, because AFUE measures fuel efficiency and says nothing about the electricity the blower consumes.
A PSC blower draws substantially more power than an ECM at the same airflow, and the gap widens dramatically if you run the fan continuously for filtration or air mixing. Over a 15-year life in a long heating season, blower electricity is a real number — and it is the one line item never shown on a comparison sheet.

FAQs
How much does a new furnace cost in 2026?
Typically $3,000 to $8,000 installed, with most homes landing between $4,500 and $6,500. Natural gas runs $3,500 to $7,500, electric $2,000 to $5,000, and oil $5,500 to $10,000 or more. Equipment accounts for only 40 to 60% of the total.
Is a high-efficiency furnace worth the extra cost?
In cold climates with long heating seasons, usually yes. But a condensing furnace on undersized ductwork cannot deliver the efficiency you paid for, because the secondary heat exchanger adds resistance to a system already restricted. Have static pressure measured before specifying high-efficiency equipment.
What size furnace do I need?
Whatever a Manual J load calculation says, based on square footage, insulation, windows, infiltration and climate zone. Sizing by square footage alone, or by matching the old unit, is guessing. Oversized furnaces short-cycle, waste fuel, and put the blower through excessive start cycles.
What is AFUE and what is a good rating?
AFUE is the percentage of fuel converted to usable heat. 80% is standard non-condensing; 90% and above is condensing, which requires PVC venting and a condensate drain. Residential gas furnaces top out around 98%.
Why do furnace quotes vary so much?
Because scope varies, not just equipment. Duct modifications, venting, gas line resizing and electrical work can add thousands, and a cheap bid often excludes them until they appear as change orders. Compare scope line by line, not just totals.
Does a new furnace include a new blower motor?
Yes, a new furnace ships with its blower. But if you are replacing only a failed blower motor rather than the whole furnace, that is a far smaller job — see our blower motor replacement cost guide.
Next Steps
Ask every bidder two questions: did you perform a Manual J, and did you measure static pressure. The answers will tell you more than the price. If your furnace is otherwise sound and only the blower motor has failed, a programmed remanufactured motor with a 2-year warranty costs a fraction of a full replacement.
