Typical buyers pay $4,200-$12,000 to replace both a furnace and an AC unit; the combined cost varies with unit size, efficiency, ductwork, and labor. This article lists furnace and AC unit cost estimates, per-unit rates, and the main price drivers to plan a replacement budget.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Furnace + AC Full Replacement (single-family) | $4,200 | $8,000 | $12,000 | Assumptions: 2.5–3 ton AC, 80–96% AFUE furnace, standard ductwork, suburban labor. |
| AC Condenser Only (per ton) | $1,000 | $1,750 | $3,000 | Per ton installed; includes basic refrigerant charge. |
| Furnace Only (per unit) | $1,800 | $3,800 | $7,000 | Depends on AFUE and staging; mid-efficiency common. |
| Duct Repair/Replacement (per run) | $300 | $1,200 | $6,000 | Simple repairs vs. full system replacement for 1,500–2,500 sq ft home. |
Total Price For Replacing a Furnace and AC In a Typical Home
Most homeowners pay $4,200-$12,000 to replace both units, with a typical single-family home landing near $8,000.
Typical totals assume a 1,500–2,500 sq ft home, a 2.5–3.5 ton AC, a 80–96% AFUE gas furnace, and standard single-stage or two-stage equipment. High-end jobs include two-stage/variable-speed compressors, 95%+ AFUE furnaces, and new thermostats or zoning.
Assumptions: Midwest labor rates, standard materials, normal attic/garage access.
Line-Item Quote Breakdown: Materials, Labor, Equipment, Permits, Disposal
Expect the quote to split into materials, labor, equipment, permits, and disposal; each can be 10–35% of the total.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $1,200 | $3,500 | $7,000 | Furnace, condenser, coil, thermostat, filters. |
| Labor | $800 | $2,000 | $4,000 | Typical 8–24 hours crew time; $75-$125 per hour. |
| Equipment & Tools | $150 | $400 | $1,200 | Vacuum pumps, gauges, crane/rigging for rooftop installs. |
| Permits & Inspections | $50 | $200 | $800 | Local code fees vary widely; larger jobs cost more. |
| Delivery/Disposal | $75 | $250 | $800 | Old unit disposal and refrigerant recovery. |
| Warranty/Extended Service | $0 | $200 | $800 | Optional factory or contractor warranties. |
How Tonnage, AFUE Rating, and Ductwork Affect the Final Quote
Increasing AC tonnage, higher AFUE furnaces, or extensive duct replacement can each add thousands to the price.
AC tonnage: 2.0 ton jobs often cost $3,500-$6,000 combined; 3.0 ton jobs generally cost $4,200-$8,000; 4.0+ ton systems frequently hit $6,500-$12,000 due to larger equipment and heavier labor. Furnace AFUE: moving from 80% to 95% commonly adds $700-$2,000. Ductwork: minor repairs $300-$1,200; full replacement for 1,800–2,400 sq ft can be $3,500-$12,000.
Practical Ways To Lower Furnace and AC Replacement Price
Control scope: replace only what fails now, postpone premium upgrades, and fix ducts instead of full replacement when possible.
Specific tactics: choose mid-efficiency models (e.g., 80–92% AFUE, single-stage 13–15 SEER) rather than premium; schedule in shoulder seasons for lower labor rates; get 3 written bids; bundle other home HVAC work to leverage contractor discounts.
How Regional Markets Change Typical Prices
Labor and permit differences cause coastal metro areas to run 15–30% higher than the national average; rural areas are often 5–15% lower.
Example deltas: Northeast/West Coast +15–30%, Mountain states +5–15%, Midwest/Rust Belt -5–10%. Urban jobs may include higher permit fees and crane costs for rooftop installs, adding $500-$2,000.
Job Duration, Crew Size, and Typical Labor Rates To Expect
Most full replacements require 8–24 labor hours and a crew of 2–3 technicians; plan for a 1–3 day job depending on complexity.
Hourly rates: $75-$125 per hour per technician in many U.S. markets. Simple swap-outs: 8–12 hours. Duct modification, electrical upgrades, or rooftop placement: 12–24+ hours. Weekend or rush jobs often add 10–25% premium.

Concrete examples help map the ranges to real scenarios.
| Scenario | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Basic Swap (Entry) | 2.5 ton AC, 80% furnace, reuse ducts | 10 | $1,400 (AC) + $1,800 (furnace) | $3,800-$4,500 |
| Mid Upgrade (Average) | 3.0 ton AC 14 SEER, 95% furnace, minor duct repair | 16 | $1,750/ton, $3,500 furnace | $6,500-$8,500 |
| High-End Replacement | 4.0 ton variable-speed AC, 98% furnace, new ducts, zoning | 24 | $2,500+/ton, $6,000+ furnace | $10,500-$16,000+ |
Common Add-Ons, Fees, and Why Quotes Differ
Expect extras like electrical upgrades, refrigerant overcharge, condensate lines, or permits to appear as line items and change totals by $200-$3,000.
Typical add-ons: electrical panel upgrades $500-$2,500, new condensate pumps $150-$400, refrigerant recharge (if leak) $200-$1,200, and crane or rooftop rigging $500-$2,500. Always ask for itemized line pricing to compare bids accurately.
