Homeowners typically pay between $3,500 and $15,000 to replace both a furnace and an air conditioner, with the average price around $7,500 depending on equipment size, efficiency, and ductwork. This article covers the average cost and the main price drivers for furnace and air conditioner replacement so buyers can budget and compare quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full furnace + AC replacement (single-family) | $3,500 | $7,500 | $15,000 | Assumptions: 2–3 ton AC, 80–95% AFUE furnace, normal access. |
| Furnace only | $1,200 | $3,000 | $6,000 | Varies by fuel type, AFUE rating. |
| AC/Heat pump only | $1,200 | $4,500 | $9,000 | Per ton installed, includes condenser and coil. |

What Replacing Both Furnace And AC Usually Costs For A Typical Home
Full replacement for a typical 1,500–2,500 sq ft single-family home with forced-air HVAC usually ranges from $3,500 to $15,000 total, with $7,500 as a realistic mid-point for a 2-ton to 3-ton system and a mid-efficiency furnace.
Average estimates assume standard 80–95% AFUE gas furnaces, 13–16 SEER air conditioners, existing ductwork in acceptable condition, and suburban U.S. labor rates.
Assumptions: Midwest labor rates, standard materials, normal access.
How The Quote Breaks Down: Materials, Labor, Equipment, Permits, Disposal
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $1,500-$6,000 (furnace) + $1,200-$6,000 (AC) | $800-$3,000 | $500-$2,500 (duct/thermostat) | $50-$400 | $100-$600 |
Materials and major equipment typically account for roughly 60–75% of the total replacement price, with labor and small fees covering the rest.

How System Size (Tonnage/BTU) And Efficiency Ratings Shift The Final Price
AC capacity is priced per ton: small splits (1.5–2.5 tons) cost about $1,200-$4,000 installed per ton range; larger 3–5 ton systems scale higher. Furnaces are priced by output: 40,000–80,000 BTU units run $1,200-$6,000 depending on AFUE and fuel.
Upgrading from a 13 SEER to a 16–18 SEER unit can add $700-$3,000; bumping furnace AFUE from 80% to 95% adds $400-$2,000.
Numeric thresholds: a 2.5-ton to 3.5-ton jump often increases AC equipment cost by ~$1,000-$2,500; switching from electric furnace to high-efficiency gas can increase installation complexity and add $1,000+ if new gas lines are needed.
How Ductwork Condition And Modifications Affect The Price
If ducts are sound, replacement focuses on units; if ducts need sealing or partial replacement, add $500-$4,000. Full duct replacement in a 2,000 sq ft home can run $3,000-$8,000 depending on layout and material.
Expect $300-$1,000 for duct sealing and $1,200-$4,000 for localized duct repairs; full system replacement is the high end.
Practical Ways To Reduce Replacement Price Without Sacrificing Safety
Choose equipment sized to the home (avoid oversized units), accept mid-efficiency ratings, schedule replacements off-peak, and obtain multiple quotes. Performing basic prep—clearing access, moving furniture, providing attic access—reduces labor time and surprises.

Simple scope controls—keeping the same fuel type, reusing undamaged ducting, and avoiding high-end thermostat packages—can cut $1,000-$3,000 from quotes.
Typical Add-Ons, Disposal Fees, And Fast-Track Charges To Budget For
Common extras include coil or condenser replacement ($700-$2,500), line-set replacement ($200-$800), refrigerant recharge ($100-$500), electrical upgrades ($300-$2,000), and thermostat upgrades ($100-$600). Rush or emergency installs add 10–30% to labor.
Removal and disposal fees commonly add $100-$600; expect additional charges where old refrigerant recovery or hazardous-material handling is required.
Regional Price Differences And Example Replacement Quotes
| Region | Typical Delta vs. National | Example Quote |
|---|---|---|
| Northeast (urban) | +10% to +25% | $9,000 for 3-ton AC + 95% AFUE furnace, includes permits and minor ductwork |
| Midwest (suburban) | -5% to +10% | $6,800 for 2.5-ton AC + 80% AFUE furnace, reuse ducts |
| South (hot climate) | +5% to +20% | $8,200 for 3.5-ton high-efficiency AC + 90% AFUE furnace, includes upgraded condenser pad |
Regional labor and permitting explain most of the variance; urban projects often cost more because of access, fees, and demand.
