| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Gas furnace or packaged unit | $1,800 | $3,200 | $5,500 | AFUE 80–95% and common 60–100k BTU ranges |
| Air conditioner or heat pump (gas furnace paired) | $2,800 | $4,900 | $7,500 | Condensing units; SEER 14–20 depending on climate |
| Labor & installation | $1,000 | $3,500 | $6,000 | Includes ductwork adjustments and system commissioning |
| Permits & inspections | $150 | $400 | $1,000 | Varies by city and scope |
| Delivery, disposal, and removal | $100 | $350 | $800 | Old unit haul-away often charged separately |
| Equipment & controls | $250 | $900 | $2,000 | Smart thermostats, zoning, and add-ons |
| Warranty, diagnostics, and contingency | $100 | $500 | $1,200 | Typically 5–10 year coverage on parts |
| Taxes | $0 | Varies | Varies | State and local rates apply |
Overview Of Costs
Typical gas furnace or packaged unit projects cost between $4,000 and $9,500, including installation and basic controls. For higher efficiency models, or when pairing with a new duct system, totals can rise to $12,000 or more. Price ranges reflect a mix of equipment quality, efficiency, and local labor rates.
The per-unit costs commonly include a furnace or boiler plus essential components for a complete system. Assumptions such as climate, existing ductwork, and chosen efficiency drive both total price and per-unit pricing. Assumptions: region, specs, labor hours
Cost Breakdown
| Materials | Labor | Equipment | Permits | Delivery/Disposal | Warranty |
|---|---|---|---|---|---|
| Furnace or condensing unit, burners, burners tubes | Labor hours vary by home and complexity | Air handler, coils, thermostat, and controls | Local permit costs | Transport and old unit removal | Parts warranty plus service plan options |

Pricing Variables
Gas furnace and air conditioner pricing is driven by efficiency, tonnage, and climate. Higher AFUE ratings, variable-speed blowers, and modulating gas valves raise upfront costs but reduce long-term fuel use. For cooling, higher SEER and ductless zones can add cost but improve comfort and efficiency. Key drivers include furnace AFUE, AC SEER, and system tonnage.
Other drivers include the length of the gas run, ductwork condition, and existing venting. If a home lacks adequate ductwork, expect additional costs for redesign or duct reconstruction. Assumptions: region, specs, labor hours
Factors That Affect Price
Labor rates vary by city and region, with urban areas typically higher than rural. Seasonal demand, permit costs, and availability of equipment also impact quotes. A system upgrade to a higher efficiency model or a smart thermostat increases price but may offer energy savings over time. Expect fluctuations driven by market supply and installation complexity.
Ways To Save
To control cost, compare multiple bids, consider replacing only essential components, and sequence upgrades (furnace first, later add central AC if needed). Some utilities offer rebates or tax credits for high efficiency gas furnaces, which can trim the net price. Planning and timing can reduce the overall spend.
Regional Price Differences
Prices differ across the country due to labor markets and material availability. In the Northeast, higher permitting and insulation work can push totals toward the high end. The Midwest often presents balanced pricing, while the South may be more price competitive due to milder winters and mid-range HVAC needs. Regionally, expect a typical delta of ±15–25% from national averages.
Labor, Hours & Rates
Installation time depends on home layout, duct system, and whether an existing furnace is being replaced. Typical labor spans 1–4 days for full upgrades in standard homes. Local hourly rates commonly fall in the range of $60–$120 per hour. Smart scheduling and clear scope help prevent surprise labor costs.
Real-World Pricing Examples
Three scenario cards illustrate common project scales. All totals include standard installation and basic controls; regional adjustments may apply. Assumptions: region, specs, labor hours
Basic
Furnace: 80 AFUE gas furnace, standard blower, compatible with existing ductwork; no major duct work or add-ons.
Labor: 14–20 hours; Parts and materials: mid-range; Per-unit: $3,400
Total: $4,800–$6,200
Notes: Suitable for homes with minimal efficiency upgrades and existing ductwork in decent condition.
Mid-Range
Furnace: 90 AFUE with modulating burner and a smart thermostat; partial duct upgrades.
Labor: 20–28 hours; Per-unit: $4,600
Total: $7,000–$9,000
Notes: Balanced efficiency and comfort with some duct or venting improvements.
Premium
Furnace: 95 AFUE or higher, variable-speed blower, whole-house zoning, new ductwork, and a high-SEER condenser.
Labor: 34–48 hours; Per-unit: $7,000
Total: $12,000–$15,500
Notes: For homes needing major duct upgrades, zoning, and advanced controls.
Local Market Variations
Markets with skilled installers and higher demand typically show higher quotes. Conversely, areas with more competition may offer lower price ranges. Consider bundled deals that include maintenance plans to protect the investment over time. Local market conditions influence final pricing.
Maintenance & Ownership Costs
Gas furnace ownership includes annual maintenance, filter changes, and potential minor repairs. A typical maintenance plan costs $100–$300 per year, while major repairs can range from $400 to $1,400 depending on components. A 5-year cost outlook shows maintenance plus possible part replacements over time. Long term costs matter for budgeting and reliability.
Permits, Codes & Rebates
Permitting costs and code compliance may add to the price, particularly in urban zones with strict energy codes. Some utilities and manufacturers offer rebates or tax incentives for high efficiency gas systems. Always verify eligible programs before finalizing a contract. Incentives can significantly affect the bottom line.
Frequently Asked Price Questions
What is the typical price for a new gas furnace installed? Most homes total $4,000 to $9,000, with higher efficiency and duct work pushing toward $12,000. How long does installation take? Most projects complete in 1–4 days, depending on complexity. Do I need permits? Yes, most jurisdictions require permits for new HVAC equipment. Careful planning reduces surprises in price and schedule.
