Most homeowners pay between $4,000 and $12,000 to replace both a furnace and an air conditioner; the exact furnace and air conditioner replacement cost depends on unit size, efficiency, and installation complexity.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace + AC Full Replacement (typical home) | $4,000 | $7,500 | $12,000 | Assumptions: 2,000 sq ft home, single-story, mid-efficiency units, standard ductwork. |
| Furnace Only | $2,000 | $4,000 | $8,000 | Includes installation and basic thermostat. |
| AC Condenser Only | $1,800 | $3,500 | $7,000 | Per condenser, excludes ductwork changes. |
| Permit / Disposal / Minor Duct Repair | $200 | $800 | $2,500 | Varies by local code and extent of repairs. |
Typical Total Price For Replacing Furnace And AC In A Single Home
Replacing both systems in a typical 1,800–2,400 sq ft single-family home commonly runs $4,000-$12,000 total, with $2,000-$5,000 for the furnace and $1,800-$7,000 for the AC condenser and coil.
Average replacement for paired systems lands near $7,500 for mid-efficiency models and straightforward installations.
Assumptions: Midwest labor rates, two installers, standard 80–95% AFUE furnace, 13–16 SEER AC, accessible equipment placement.
Cost Breakdown: Materials, Labor, Equipment, Permits, And Disposal
Typical quotes split into materials, labor, equipment rental, permits, and disposal; understanding each line helps compare contractors.
| Item | Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|---|
| Furnace | $1,200-$4,500 | $400-$1,200 | $0-$200 | $50-$300 | $50-$200 |
| Air Conditioner | $1,200-$5,500 | $500-$1,500 | $0-$300 | $50-$300 | $50-$300 |
| Ductwork / Sheet Metal | $300-$3,000 | $500-$2,500 | $0-$150 | $0-$100 | $0-$100 |
| Controls / Thermostat | $75-$600 | $75-$300 | – | $0-$50 | $0-$25 |
Labor commonly runs $75-$125 per hour; is a simple way to estimate crew cost.
How Unit Size, SEER Rating, And AFUE Change The Final Quote
Unit capacity and efficiency drive material costs: larger tons or higher SEER/AFUE add 15–60% to equipment pricing compared with base models.
Expect price jumps near common thresholds: 2.5→3.0 ton, 14→16 SEER, and 80%→95% AFUE often increase equipment cost materially.
Example thresholds: 1.5–2.5 ton ($1,800-$3,500), 3.0–5.0 ton ($3,000-$6,500); 13 SEER baseline vs 16 SEER +$800-$2,000.
Practical Ways To Reduce Furnace And AC Replacement Price
Scope control reduces cost: keep existing ductwork if in good condition, choose mid-efficiency units, schedule install off-peak, and get at least three detailed quotes to compare scopes.
Repairing or sealing ducts can save $1,000-$3,000 versus full duct replacement and often postpones major expense.
Options to trade off: lower SEER for lower upfront cost, financing vs cash purchase, and bundling with other HVAC work for contractor discounts.
How Prices Differ From Region To Region In The U.S.
Coastal and urban markets run 10–35% above national averages; rural and interior regions often run 5–20% below average due to labor and overhead differences.
Typical regional deltas: Northeast/West Coast +15–35%; Southeast +5–20%; Midwest -5–15% relative to the national average.
Assumptions: similar unit specs; differences reflect prevailing wage, permit costs, and contractor margins.
Common Add-Ons, Removal Fees, And Permit Charges To Budget
Expect extra line items for refrigerant recovery ($75-$300), old equipment disposal ($50-$300), safety upgrades or venting ($200-$1,200), and permits ($50-$300+).
Factor $400-$1,500 of add-ons on most replacement projects unless the quote explicitly includes removal, permits, and code compliance work.
Examples: new flue or chimney liner $300-$1,200; electrical upgrades $300-$1,500; refrigerant retrofit $500-$2,000 if systems are incompatible.
Three Real-World Quote Examples With Specs And Labor Time
| Scenario | Specs | Labor Hours | Total |
|---|---|---|---|
| Budget Replace | 80% AFUE furnace, 13 SEER 2.5 ton AC, reuse ducts | 10-14 hours | $4,000-$5,200 |
| Mid-Range | 95% AFUE furnace, 16 SEER 3.0 ton AC, minor duct sealing | 14-22 hours | $7,000-$9,000 |
| High-End | Dual-stage 98% AFUE, 20 SEER 4.0 ton, new ductwork, smart controls | 24-40 hours | $11,000-$18,000 |
These examples show how labor time and equipment specs combine to move a quote from low to high ranges.
