New Gas Furnace Cost Guide 2026
Prices for a new gas furnace vary widely based on efficiency, size, and installation requirements. Typical cost drivers include unit AFUE rating, ductwork condition, and local labor rates. The following figures cover common U.S. scenarios and provide clear cost ranges for budgeting and pricing estimates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace Unit (gas, 80%–98% AFUE) | $1,200 | $2,800 | $4,500 | Single-stage to modulating models; higher AFUE costs more upfront |
| Installation Labor | $1,000 | $2,000 | $3,000 | Includes removal of old unit, hookup, and basic venting |
| Ductwork & Combustion Venting | $500 | $1,500 | $3,000 | Repairs or relocations add to cost |
| Permits & Codes | $0 | $250 | $1,000 | Depends on local requirements |
| Electrical & Gas Piping | $300 | $800 | $1,800 | May require upgrades for high-efficiency models |
| Delivery & Removal of Old Equipment | $100 | $350 | $600 | Included in some offers |
| Misc. Add-Ons & Warranties | $100 | $400 | $1,000 | Extended warranties vary by provider |
| Estimated Total Installed Cost | $2,700 | $7,300 | $14,000 | Assumes standard home with adequate ductwork |
Overview Of Costs
New gas furnace pricing includes both the unit and installation, with the total range strongly influenced by AFUE efficiency, blower type, and ease of access. The per-unit range commonly falls between $1,200 and $4,500 for the furnace itself, while installed project totals span from about $2,700 to $14,000 depending on complexity. Assumptions: region, specs, labor hours.
Cost Breakdown
Below is the typical breakdown of a complete furnace replacement project. The table highlights the main cost categories and how they contribute to the final price.
| Category | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $1,200 | $2,400 | $4,200 | Furnace + control board + filters |
| Labor | $1,000 | $2,000 | $3,000 | Installation crew hours |
| Equipment | $0 | $500 | $1,000 | Optional added components |
| Permits | $0 | $250 | $1,000 | Local code compliance |
| Delivery/Disposal | $0 | $300 | $600 | Old unit removal |
| Warranty & Service Plans | $0 | $200 | $600 | Annual coverage options |
| Overhead & Profit | $200 | $700 | $1,500 | Contractor margin |
| Taxes | $0 | $180 | $900 | State/local taxes |

What Drives Price
Efficiency and size are primary price levers. Higher AFUE models (90%–98%) cost more upfront but reduce monthly fuel use. A furnace’s size must match home load; oversized or undersized units increase both equipment and installation complexity. SEER ratings apply to central air, but furnace sizing often uses Manual J calculations and blower configuration. Other drivers include ductwork condition, venting complexity, and accessibility of the furnace location.
Ways To Save
Cost-conscious buyers can pursue several strategies without sacrificing reliability. Consider standard efficiency models if heat load permits; request multiple bid estimates; bundle with air conditioner replacements if needed; and plan installations during off-peak seasons where contractors have more capacity. Getting accurate load calculations minimizes wasted spend on oversized units and future comfort complaints.
Regional Price Differences
Prices vary by region due to labor markets and permitting. In the Northeast, installed costs tend to be higher due to stricter codes and higher labor rates; the Midwest often presents mid-range pricing; the South may run lower due to lower overall labor costs. The spread across regions typically ranges ±15% to ±25% from the national average, influenced by ductwork needs and fuel prices.
Labor & Installation Time
Typical installation takes 1–2 days for a straightforward replacement; more complex jobs can require 3–4 days. Labor costs account for crew size, permits, and potential duct modifications. Expect longer timelines if ductwork or gas line upgrades are required, which can add $500–$2,000 to total costs depending on length and complexity.
Real-World Pricing Examples
Three scenario cards illustrate how the numbers work in practice.
Basic: 80% AFUE furnace, standard ductwork, minimal modifications; 1–2 days; parts mostly from the furnace package. Specs: 60,000 BTU, basic gas valve, standard thermostat. Labor 8–14 hours; total installed price around $2,700–$4,000.
Mid-Range: 90% AFUE furnace, some duct sealing, optional humidifier; 2 days; better warranty. Specs: 80,000 BTU, upgraded blower, smart thermostat. Labor 14–22 hours; total around $4,500–$7,000.
Premium: 95%–98% AFUE, complete ductwork retrofit, advanced venting, high-end warranty; 2–4 days. Specs: 100,000 BTU, variable-speed blower, multiple zones. Labor 22–40 hours; total about $8,500–$14,000.
Assumptions: region, specs, labor hours.
Permits, Codes & Rebates
Some jurisdictions require permits for furnace replacement, with typical fees ranging from $0 to $1,000. Local rebates or utility incentives can offset a portion of the cost, especially for high-efficiency models or equipment branded as energy savers. Check local incentives before scheduling installation to maximize overall savings.
Regional Price Differences
Comparison across three U.S. markets shows how local factors influence final quotes. In Urban areas, prices frequently run 10–25% higher than Rural equivalents due to contractor demand and permitting complexity. Suburban markets often fall between these two, with variance driven by home age and ductwork accessibility. For budget planning, apply a regional delta of ±15%–25% around your local average.
