Buying a new furnace typically ranges from about $3,000 to $9,000, including installation. The main cost drivers are furnace type (gas vs electric), efficiency (AFUE), ductwork needs, and labor. Prospective buyers should expect a larger upfront investment if extensive ductwork or ventilation work is required.

| Installation Labor | $1,500 | $3,000 | $5,000 | Includes removal of old furnace and hookups. |
| Ductwork Modifications | $500 | $2,000 | $4,000 | Needed if airflow is insufficient. |
| Venting & Gas Lines | $300 | $1,200 | $2,000 | Permits may apply in some areas. |
| Permits & Inspections | $50 | $300 | $1,000 | Local requirements vary widely. |
| Delivery/Removal of Old Unit | $100 | $500 | $1,000 | Included in some packages. |
| Warranties & Extras | $0 | $300 | $800 | Extended warranties add cost. |
Overview Of Costs
Understanding the total project range helps set a realistic budget. A typical installed furnace project falls in the $3,000-$9,000 band, with most homeowners paying $4,500-$7,000. The per-unit price for the furnace itself commonly runs $1,800-$4,000, while installation adds $1,500-$5,000 depending on complexity. Assumptions: gas furnace, mid-range efficiency, standard ductwork, and a non-urban setting.
Per-unit estimates can be helpful for quick comparisons: furnace alone often $1,800-$3,500, installation $1,500-$5,000, and any necessary duct or vent work varies by house layout. Budget planning should account for potential hidden costs such as duct sealing or electrical upgrades.

What Drives Price
Key price drivers include furnace type, efficiency, and installation complexity. Gas furnaces commonly cost more upfront than electric units, but running costs differ by fuel type. Efficiency, measured as AFUE, increases upfront price but lowers long-term energy bills. Ductwork quality and any required modifications can add substantial sums, especially in homes with old or leaky ducts. SEER-related or tonnage requirements for cooling integration may also influence the overall package.
Ways To Save
Practical steps to reduce upfront costs without sacrificing performance. Seek local rebates and utility incentives for high-efficiency models. Compare quotes from at least three installers and check for bundled services that include ductwork evaluations. Consider mid-range efficiency unless climate or energy prices justify a higher-efficiency unit. Maintenance plans can reduce unexpected repairs and extend system life.
Regional Price Differences
Prices vary by market, with notable deltas between regions. In the Northeast, installation may rise due to complex venting and older homes, often adding 5-15% compared to the national average. The Midwest tends to be closer to average, while the West Coast may see higher permit and labor costs, sometimes pushing totals 5-12% above typical ranges. Rural areas can be 8-15% cheaper for basic installs, but transport and service area availability may offset savings.
Labor & Installation Time
Labor hours largely determine the final bill. A straightforward gas furnace replacement might take 1–2 days, including tear-out and start-up, totaling about 8–16 hours of labor. More complex installs with ductwork alterations or new gas lines can run 2–3 days or longer, equating to 16–40 hours of labor. When quoting, contractors should itemize labor by crew size and time, with a clear schedule for permits and inspections.
Real-World Pricing Examples
Sample scenarios help translate ranges into concrete expectations. Assumptions: single-story home, standard ductwork, central thermostat, existing vent locations.
- Basic: Gas furnace, mid-range AFUE, limited duct repairs. Unit $2,000; Installation $2,000; Permits $150; Total $4,150.
- Mid-Range: Gas furnace, higher AFUE, minor duct sealing. Unit $2,800; Installation $3,000; Duct work $800; Permits $250; Total $6,850.
- Premium: High-efficiency unit, major duct redesign, new venting. Unit $4,000; Installation $4,500; Ducts $2,000; Permits $600; Total $11,100.
Permits, Codes & Rebates
Regulatory steps can influence final costs. Some jurisdictions require permits, inspections, and gas line tests, which add $50-$1,000 depending on locality. Energy rebates and utility incentives can offset part of the upfront cost, particularly for high-efficiency models. A thorough installer should flag permit needs during the proposal stage and help with documentation to access incentives.
Maintenance & Ownership Costs
Ongoing costs affect long-term budgeting. Annual maintenance averages $100-$250 and prevents major failures. Expect filter replacements every 1–3 months, typically $20-$60 per filter. Five-year cost outlook, assuming regular service, places total ownership around 2.5x to 3x the initial installed price if no major repairs occur.
Pricing FAQ
Common questions about furnace pricing. How much does a furnace replacement cost? Typical installed range is $3,000-$9,000, with variations by efficiency, fuel type, and ductwork needs. Do I pay more for higher AFUE? Yes, higher AFUE models start pricier but save on annual energy bills. Are rebates worth chasing? Often yes, if eligible; they can cut upfront costs by several hundred dollars.
