Buyers replacing both a furnace and central air conditioner typically pay a combined cost that ranges widely by home size, equipment efficiency, and installation complexity. New furnace air conditioner cost for a typical single-family home is commonly $7,000-$14,000, with higher prices in urban or high-efficiency installs.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Standard Split System (furnace + AC) | $4,500 | $8,500 | $15,000 | 1,500–2,500 sq ft home; mid-efficiency units |
| High-Efficiency Combo (95% AFUE furnace, 16–20 SEER AC) | $8,000 | $12,000 | $20,000 | Includes upgraded ductwork and smart thermostat |
| Mini-Split Combo (ductless) | $5,500 | $10,000 | $18,000 | Per-zone pricing; good for partial replacements |
Typical Total Price And Per-Unit Pricing For Combined Furnace + AC
Assumptions: Midwest labor rates, standard 2,000 sq ft home, moderate access.
For a full furnace and central air replacement, total price typically falls between $4,500 and $20,000 depending on capacity and efficiency; the average is about $8,500. Expect per-unit equipment ranges of $1,200-$4,500 for furnaces and $1,800-$6,500 for air conditioners.
Per-ton AC pricing: $1,200-$3,000 per ton for equipment alone; typical home needs 2–5 tons. Furnace pricing by input: $1,200-$2,000 for 80% AFUE gas furnace, $2,000-$4,500 for 95%+ AFUE condensing furnace.
Breakdown Of Major Quote Components: Materials, Labor, Equipment, Permits
| Component | Low | Average | High |
|---|---|---|---|
| Equipment (furnace + AC) | $3,000 | $6,000 | $12,000 |
| Labor (installation) | $1,200 | $2,500 | $5,000 |
| Materials & Accessories | $300 | $900 | $2,000 |
| Permits & Tests | $75 | $200 | $600 |
| Delivery / Disposal | $75 | $200 | $500 |
Labor typically accounts for 20%–40% of the total quote depending on ductwork and difficulty.
How Size, SEER, And AFUE Change The Final Quote
Major price drivers include system capacity (tons), AC SEER rating, and furnace AFUE. Moving from 13 SEER to 16 SEER can add $800-$2,500 to equipment cost; upgrading furnace from 80% to 95% AFUE can add $800-$2,000.
Numeric thresholds: homes under 1,200 sq ft often need 1.5–2.5 tons; 1,200–2,500 sq ft usually need 2.5–4 tons; over 2,500 sq ft often need 4+ tons. Long refrigerant line sets over 50 ft or vertical risers above 20 ft add $300-$1,200.
Concrete Ways To Reduce Combined Furnace And AC Price
Controlling scope and timing reduces cost: schedule replacement in spring or fall, accept a mid-efficiency SEER, and keep existing ductwork when in good condition. Comparing 3-5 written quotes and requesting itemized bids can save 5%–15% off average prices.
Other savings: bundle with other home services for contractor discounts, perform simple prep (clear attic access, remove obstacles), and replace only one component if diagnostics show only minor AC or furnace faults.
Regional Price Differences Across U.S. Markets
Regional deltas: Northeast and West Coast prices run 8%–20% higher than Midwest; urban areas can add 5%–15% for labor access and permits. Budget $8,000-$14,000 in high-cost metro areas versus $6,000-$10,000 in lower-cost regions for similar equipment.
Climate effect: hotter climates often require larger AC capacity and higher SEER, raising upfront cost but lowering operating expense over time.
Common Add-Ons, Repairs, And Time-On-Site Estimates That Affect Price
Typical add-ons: duct sealing or replacement ($500-$6,000), smart thermostat ($150-$400), line set replacement ($300-$1,200), electrical upgrades ($200-$1,200). Expect 6–14 hours of technician labor for a straight swap; complex installs with ductwork take 1–3 days.
Minimum charges and diagnostic fees: $75-$150 for service calls; rush installs or after-hours work can add $150-$500.
Three Real-World Quote Examples With Specs And Totals
| Example | Specs | Labor Hours | Equipment | Total |
|---|---|---|---|---|
| Basic Swap | 2.5-ton 13 SEER AC + 80% AFUE furnace; existing ducts ok | 8 | $3,500 | $5,000-$6,000 |
| Mid-Efficiency Upgrade | 3.5-ton 16 SEER AC + 95% AFUE furnace; minor duct sealing | 12 | $7,000 | $9,000-$11,000 |
| High-End Retrofit | 4.5-ton 20 SEER AC + 98% AFUE condensing furnace + new ducts | 24 | $13,000 | $15,000-$22,000 |
These examples illustrate how capacity, efficiency, and ductwork change both labor hours and the total price.
Questions To Ask When Getting A Quote That Impact Final Price
Ask for equipment model numbers, SEER and AFUE ratings, itemized labor hours, ductwork condition, permit coverage, and warranty specifics. Requests for itemized quotes and clear warranty terms prevent surprise charges and make side-by-side comparisons meaningful.
When evaluating quotes, verify if refrigerant type (R-410A vs alternatives), included thermostat, and disposal fees are listed to compare true out-the-door pricing.
