Prices for Goodman furnace installation commonly range from $2,600 to $7,000, depending on furnace size, efficiency, ductwork, and installation complexity. The main cost drivers include unit price (AFUE rating and tonnage), labor time, permits, and any required duct or vent work. The following sections present a practical price landscape in USD with clear low–average–high ranges and per-unit details.

| Goodman Furnace Unit (Gas, 2-5 Ton) | $1,600 | $2,600 | $4,000 | Standard 80-96% AFUE options |
| Installation Labor | $850 | $2,000 | $3,000 | Includes removal of old unit |
| Permits & Inspections | $50 | $250 | $600 | varies by locality |
| Ductwork Modifications | $200 | $900 | $2,000 | depends on length and complexity |
| Venting & Flue Piping | $150 | $350 | $900 | includes gas line work if needed |
| Electrical & Gas Line Prep | $100 | $350 | $800 | upgrades may be required |
| Waste Removal & Cleanup | $50 | $150 | $350 | |
| Total Project Range | $2,800 | $7,000 | $14,000 | Includes high-efficiency options and extensive duct work |
| Per-Unit Cost ($/ton or $/kW) | $1,200 | $2,000 | $3,000 | Based on size and efficiency |
Assumptions: region, specs, labor hours.
Overview Of Costs
Total project ranges for Goodman furnace installation typically span $2,800 to $14,000, with most residential installs between $3,500 and $9,000. For a standard 2-3 ton gas furnace with 90% AFUE, expect the middle of the range around $3,800 to $6,500 installed. Higher-efficiency models (95%+ AFUE) and larger tonnage (4-5 ton) tend to push the high end toward $8,500–$12,000, especially when extensive ductwork or pacing control upgrades are required.
Per-unit ranges help set expectations: most Goodman 2-3 ton units cost $1,600–$2,600 for the equipment, while installation labor adds $850–$2,000 on average. A mid-range total for a straightforward replacement is often around $4,000–$6,500, including permits and basic duct adjustments.

Factors That Affect Price
Efficiency and size drive the price. Higher-efficiency Goodman furnaces (AFUE 95%+) cost more upfront but may save on monthly energy bills. Tonnage matters: a 2-3 ton unit is cheaper than a 4-5 ton system. Installation complexity, including long duct runs, high rises, or difficult access, can add substantially to labor and parts costs. Converting from electrical resistance heat or upgrading the gas line also shifts pricing.
Ways To Save
Get multiple bids and schedule in shoulder seasons. In many markets, fall shoulder months offer lower labor demand. Some savings come from sticking with standard ductwork layouts and avoiding additional cold- or hot-air returns. Consider a mid-range AFUE unit if current bills are moderate, and bundle with needed maintenance to spread costs.
Regional Price Differences
Prices can vary by region due to local labor markets, permitting, and climate considerations. In the Northeast, total project costs may run 5–12% higher than national averages, driven by stricter codes and older ductwork remediation. In the Southeast, installation can be on the lower end if existing accessible ductwork is adequate. In rural areas, travel time and parts availability can add a modest premium or delay. (Regional delta: ±5–12%.)
Labor & Installation Time
Typical installation takes 1–2 days for a straightforward replacement, with longer timelines for ductwork replacements or multi-zone systems. Labor costs commonly range from $850 to $2,500, depending on crew size and region. A complex install with zoning, smart thermostats, and enhanced filtration can push labor toward the upper end of the range.
Additional & Hidden Costs
Surprises include duct cleaning, extensive sealing, and enhancements like new air handlers or humidifiers. Gas line upgrades, upgraded venting, or electrical service improvements can add $300–$1,000 beyond base estimates. Always verify whether permits, inspections, and disposal fees are included in the quote to avoid underestimating the total.
