This article breaks down the price of a new furnace, including installed costs, common price drivers, and ways to save. The cost ranges reflect typical Midwest to coastal labor, standard equipment, and common installation scenarios. Readers will see low, average, and high estimates with per-unit or per-system figures where relevant.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed gas furnace (new, 80%+ AFUE) | $3,000 | $5,000 | $8,000 | Includes unit, labor, basic venting, startup |
| Installed gas furnace (90%+ AFUE) | $3,500 | $6,000 | $9,500 | Higher-efficiency models cost more upfront |
| Installed electric furnace | $2,500 | $4,500 | $6,500 | Lower fuel costs may offset some upfront |
| System replacement with heat pump (hybrid)** | $7,000 | $12,000 | $20,000 | For paired heat pump + furnace setups |
| Annual service/inspection (first year included sometimes) | $100 | $180 | $350 | Maintenance not always bundled |
| Typical labor rate per hour | $75 | $100 | $125 | Regional variation applies |
Assumptions: Midwest to coastal regions, standard new-unit installation, typical ductwork in place, normal access, 3–4 ton system for a 1,500–2,000 sq ft home.
Typical Price In Final Installed Range For Different Furnace Types
Homeowners usually pay between $3,000 and $8,000 for a complete gas furnace installation, with most projects landing around $5,000 to $6,500. The main drivers are furnace size (tonnage), AFUE efficiency, existing ductwork, and whether venting or electrical upgrades are needed. Per-unit prices for the furnace itself often fall in the $1,800 to $4,000 range depending on efficiency and brand, while labor commonly runs $1,200 to $2,800.
Electric furnaces tend to be cheaper upfront, typically in the $2,500 to $6,500 installed range, depending on whether a new air handler or heat exchanger is included. For higher-efficiency gas models (90%+ AFUE) the installed total tends to lean toward the upper end of the spectrum, especially if gas lines or venting require retrofit. Cost variability rises with older ductwork, attic access, or the need for a new thermostat, zoning, or filtration upgrades.
Major Cost Components In A Furnace Quote
The quote for a new furnace is usually broken into fixed and variable components. The following table highlights four to six cost groups commonly seen in residential quotes.
| Component | Typical Range | Per-Unit or Per-Job | Common Factors | Notes |
|---|---|---|---|---|
| Furnace unit | $1,800-$4,000 | Per unit | AFUE, brand, modulating vs single-stage | Higher efficiency, variable-speed blowers add cost |
| Labor for installation | $1,200-$2,800 | Job | Crew size, complexity, access | Includes mounting, wiring, venting |
| Ventilation/lines and venting alterations | $400-$1,800 | Line item | Metal vs PVC venting, length, elbows | Gas venting can add complexity |
| Electrical upgrades | $200-$1,000 | Line item | Breaker panel, wiring, conduit | Required for high-efficiency or electric furnaces |
| Thermostat and controls | $150-$500 | Line item | Smart or wifi-enabled controls | Can be bundled with installation |
| Permits and inspections | $100-$500 | Line item | Local requirements | Not always required; varies by region |
| Delivery and disposal | $50-$300 | Line item | Old unit haul-off | Low in well-serviced areas |
Assumptions: Standard 3–4 ton gas furnace, typical ductwork intact, no major structural changes.
What Changes The Final Quote For A New Furnace
Two variables most strongly shift the final price. First, the furnace’s efficiency rating (AFUE) and system type affect both unit cost and required venting or controls. A 90% AFUE model or dual-stage/variable-speed blower adds cost but cuts fuel usage over time. Second, the existing ductwork and installation complexity can push costs higher if ducts are leaky, kinked, or require sealing and resealing. A project that needs attic access, long duct runs, or a new return plenum will show a higher price.
Numeric examples: a standard 3-ton 80% AFUE gas furnace with simple ductwork may sit near $4,000–$6,000 installed, while a 96% AFUE model with a new plenum and duct sealing might run $6,500–$9,500 installed in a typical two-story home.
Regional Price Variations And Scheduling
Prices vary by region due to labor norms and codes. In warmer regions with milder winters, installations for an electric furnace may cluster lower, while northern markets with stricter efficiency standards can see higher installed costs. Scheduling flexibility also matters: urgent installations in peak demand periods (late fall) can carry small surge fees, whereas off-season work may qualify for discounts.
Regional delta example: Midwest standard installation may be $4,500–$7,000; West Coast with high-permit requirements may be $5,500–$9,000.
Size, System Type, And Efficiency: Concrete Details
Size and system type are among the most concrete price drivers. Typical 1,500–2,000 sq ft homes use 3–4 ton furnaces; installing a 2-stage or variable-speed model adds roughly $1,000–$2,500 to the unit cost. For heat pumps paired with a furnace (hybrid systems), total project costs commonly rise to the $7,000–$20,000 range depending on climate, ductwork, and accessories.
Efficiency tier matters: stepping from 80% to 95% AFUE can add $500–$1,500 upfront but can lower annual fuel costs and improve comfort.
Labor Time, Crew Size, And Billing Practices
Labor time scales with crew size and job complexity. A standard installation usually takes 1–2 days for a single-family home with prepped ductwork. Labor rates commonly range from $75 to $125 per hour, with some markets charging a daily crew rate for larger teams. Some contractors provide a fixed project price, while others bill hourly plus material costs.
Expect 10–20% variability due to site access, old ductwork, and required upgrades like a new electrical panel.
Smart Controls, Zoning, And Additional Upgrades
Upgrades such as smart thermostats, zone controls, air purification, and enhanced filtration add to the price. A basic thermostat is a small add-on, but a full zoning and sensor network can push total costs higher by $1,000–$3,000 depending on the number of zones and the control platform chosen. In some markets, rebates reduce the net outlay for efficient systems.
Budgeting note: plan for a 5–15% contingency to cover unexpected ductwork repairs or minor electrical changes.
Maintenance And Long-Term Costs To Consider
Initial purchase price is only part of the cost picture. Routine maintenance, annual tune-ups, and potential repairs influence long-term costs. Many contractors offer maintenance plans in the $150–$300 per year range, which can extend equipment life and preserve efficiency. Expect occasional part replacements (ignitors, sensors) over the system’s life, typically under $200–$600 per occurrence.
Five-year ownership costs often show savings from better efficiency with higher AFUE models, offsetting higher upfront prices.
