Prices for a new high-efficiency gas furnace in the U.S. vary by unit efficiency, furnace size, and installation specifics. This guide covers typical cost ranges and the main drivers, including AFUE rating, unit size, and ductwork needs. The data below uses standard midwest to southeast market conditions.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace Unit (new, high-efficiency) | $1,000 | $2,300 | $3,500 | AFUE 90%–98% models |
| Installation Labor | $1,500 | $2,200 | $3,500 | Includes basic wiring, venting, and labor |
| Modifications & Ductwork | $400 | $1,200 | $3,000 | May be needed for nonstandard homes |
| Permits & Inspections | $50 | $150 | $350 | Local requirements vary |
| Venting/ venting kit | $150 | $350 | $700 | Direct-vent or concentric venting may add cost |
| Delivery/Removal of Old Furnace | $50 | $150 | $400 | Depends on location and disposal rules |
| Taxes & Misc Fees | $60 | $140 | $300 | State/local taxes |
Overview Of Costs
Cost ranges reflect unit price plus installation and typical modifications. The total project often falls between $3,000 and $8,000 before discounts or rebates. Assumptions: typical single-family home, standard ductwork, and brick-and-mortar construction.

What Drives Price
Key price drivers include AFUE rating and furnace size. Higher AFUE (90%–98%) yields better annual fuel savings but raises upfront costs. The required BTU output depends on home size, climate, and insulation. Additional drivers include existing ductwork condition, venting complexity, and whether a full system upgrade (air handler, zoning, or ECM blower) is chosen. Assumptions: moderate climate, typical insulation, and standard duct layout.
Pricing Variables
Other important factors are installation time, crew availability, and regional labor rates. Shorter job windows with compact ductwork reduce costs, while extensive duct remediation or multiple stories raise both labor and materials.
Ways To Save
Strategy focus areas include evaluating local rebates and choosing standard configurations. Consider matching furnace AFUE to expected energy savings and avoiding premium features that do not fit home needs. Scheduling installation during off-peak seasons or negotiating bundled services can lower total expenditures. Assumptions: home already has adequate electrical capacity.
Regional Price Differences
Prices vary by region due to labor markets and material availability. In three representative markets, total installed costs may diverge by about +/- 15% from the national average.
- Coastal metro: higher ductwork and ventilation costs due to tighter spaces.
- Midwest rural: lower labor rates but possible delivery fees.
- Sun Belt suburban: balanced pricing with steady demand.
Labor & Installation Time
Typical installation takes 1–2 days for most homes, with 8–16 hours of crew time depending on duct changes and venting needs. Labor rates commonly range from $70 to $120 per hour per technician, with a two-person crew common for standard installs. Assumptions: single-story home, no major modifications.
Additional & Hidden Costs
Unexpected items can add $300–$1,000 or more, such as extra electrical work, refrigerant checks, or upgrading gas lines. Hidden costs include disposal fees and permit rechecks if code updates occur during installation. Assumptions: no structural upgrades required.
