A/C Furnace Replacement Cost Guide 2026
Costs for replacing an air conditioner and furnace in the United States typically reflect unit efficiency, system size, and labor needs. The main price drivers are equipment efficiency (AFUE and SEER), furnace/fan coil size, ductwork condition, and installation logistics. This guide presents practical price ranges and breakdowns to help buyers plan a budget for a full A/C and furnace replacement.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| System Installed Price | $6,500 | $9,500 | $15,000 | Includes equipment, basic installation, and standard ductwork |
| Heat Pump Option | $7,000 | $11,000 | $18,000 | Hybrid or all-electric setups differ by climate |
| Labor & Installation | $2,000 | $3,500 | $5,000 | Crew rates vary by region and job complexity |
| Permits & Inspections | $100 | $400 | $1,000 | Local requirements vary |
| Ductwork Modifications | $1,000 | $3,000 | $6,000 | Depends on house size and access |
Overview Of Costs
Typical project ranges combine equipment costs with professional installation. A mid-range 16 SEER air conditioner and 80+ AFUE furnace commonly falls between $8,000 and $12,000 installed. For higher efficiency models or larger homes, totals often rise to $12,000–$18,500. In some cases, a complete replacement with premium equipment and extensive ductwork may exceed $20,000. Assumptions: region, home size, existing ducts.
Cost Breakdown
| Column | Materials | Labor | Equipment | Permits | Taxes |
|---|---|---|---|---|---|
| Typical Range | $2,000–$5,500 | $2,000–$3,500 | $4,000–$9,000 | $100–$1,000 | $700–$2,000 |
| Assumptions | Furnace + AC coil, standard ductwork | Labor hours typical for 2–3 techs | Mid-range equipment; high-efficiency options cost more | Electrical/permit varies | State and local sales tax |
What Drives Price
Key price drivers include system efficiency, tonnage and cooling load, and ductwork condition. A 2-ton system with 16 SEER and an 80 AFUE furnace costs less than a 4-ton, 20 SEER setup with a 95 AFUE furnace. Duct sealing, zoning, and smart Thermostats add optional costs. Assumptions: climate, home layout, existing equipment.
Ways To Save
Shop for energy-efficient equipment only if the long-term savings justify the upfront cost. Consider seasonal discounts, bundling AC and furnace replacement, and requesting price quotes that include a 10–15 year parts and labor warranty. Avoid unnecessary upgrades if the current ductwork is in good shape. Assumptions: local promotions, warranty terms.
Regional Price Differences
Prices vary by market: urban areas tend to have higher labor rates than suburban or rural areas. In the Northeast, a mid-range install may run 5–12% above the national average; the Southeast often aligns with the average or slightly below; the Midwest can diverge by 0–8% depending on demand and accessibility. Assumptions: regional labor rates, contractor availability.
Labor, Hours & Rates
Typical installation uses 2–3 technicians over 6–12 hours for a standard replacement. Labor rates commonly range from $75 to $150 per hour per technician, with higher rates for complex ductwork or emergency service. Assumptions: crew size, project duration.
Additional & Hidden Costs
Hidden costs can include refrigerant recharge if lines were damaged, electrical panel upgrades, or refrigerant containment fees. If ducts require substantial repair, add $1,000–$4,000. Delivery, disposal fees, and sensor wiring may add $200–$1,000. Assumptions: existing infrastructure, refrigerant type.
