Most U.S. homeowners pay between $6,000 and $14,000 to replace both a furnace and central air conditioning together; price depends on system size, efficiency, ductwork condition, and installation complexity. This article focuses on realistic new furnace and AC cost ranges and the main drivers buyers see on quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete Furnace + AC Package | $4,500 | $9,000 | $18,000 | Assumptions: typical 2,000 sq ft home, mid-efficiency units, normal access. |
| Furnace Only | $1,800 | $4,200 | $8,000 | Furnace size 60k–120k BTU, includes basic install. |
| AC Condenser + Coil Only | $2,200 | $4,800 | $10,000 | 3–5 ton units, includes basic install. |
| Ductwork Repairs | $500 | $2,500 | $8,000 | Per run fixes to full replacement. |
Typical Total Price For A New Furnace And AC Package
Buyers replacing both systems together usually see total prices of $4,500-$18,000, with $6,000-$12,000 most common for single-family homes. Average quotes assume a 2,000 sq ft house, 3–5 ton AC, 80k–100k BTU furnace, and standard single-story access.
Assumptions: Midwest labor rates, standard SEER 14–16, AFUE 80–95, normal permit needs.
How Installation Quotes Break Down By Materials, Labor, Equipment, And Permits
Major cost components typically include equipment, labor, ductwork, permits, and disposal; expect equipment to be the single largest line item. Equipment + labor usually make up 75%–90% of a complete package price.
| Materials | Labor | Equipment | Permits |
|---|---|---|---|
| $1,800-$8,000 | $1,200-$4,500 | $2,200-$10,000 | $50-$800 |
| Delivery/Disposal | Accessories | Warranty | Contingency |
| $75-$500 | $200-$1,200 | $0-$1,500 | $300-$1,500 |
Which Specific Variables Most Change The Final Quote
Unit capacity, efficiency, duct condition, and installation complexity are the largest drivers; each can add thousands to the final price. Upgrading AC from 14 SEER to 20 SEER often increases equipment cost by $1,500-$4,000.
Other numeric thresholds to watch: adding a second-zone system (+$1,200-$4,000), replacing full ductwork for a 2,000 sq ft house ($4,000-$8,000), or switching from single-stage to variable-speed furnace (+$800-$2,500).
Practical Ways To Reduce The Price On Furnace And AC Replacement
Controlling scope and timing cuts cost: keep equipment to mid-range efficiency, schedule during shoulder seasons, and fix only necessary ductwork. Bundling furnace and AC with the same contractor usually reduces combined labor and access fees by 10%–20%.
- Accept mid-efficiency units (SEER 14–16) to save $1,000–$3,000 vs high-efficiency models.
- Provide clear access and do minor prep work to reduce labor hours.
- Get 3 written quotes and compare identical specs to avoid upcharges.
- Repair ducts instead of full replacement when leakage is under 20%.
How Prices Vary Across U.S. Regions And Climate Zones
Labor and permit costs cause regional differences: coastal and metropolitan areas are pricier than rural inland regions. Expect prices ~10%–25% higher in the Northeast and West Coast versus the Midwest and South for equivalent systems.
| Region | Typical Package Price | Regional Delta |
|---|---|---|
| Midwest | $6,000-$10,000 | Baseline |
| South | $5,500-$9,500 | -5% to 0% |
| Northeast | $7,000-$12,000 | +10% to +20% |
| West Coast | $8,000-$14,000 | +15% to +25% |
Labor Time, Crew Size, And Typical Installation Duration
A straightforward furnace and AC swap for a 1–2 story home typically takes 8–16 hours with a 2–3 person crew; complex jobs may need 2–4 days. Budget $75-$125 per hour for technician labor or $1,200-$4,500 total labor on most installs.
- Standard swap (no duct changes): 8–12 hours, 2 techs.
- Swap with moderate duct repairs: 12–24 hours, 2–3 techs.
- Full duct replacement or multi-zone: 2–4 days, larger crew.
Common Add-Ons, Removal Fees, And Permits That Raise The Price
Typical extras include refrigerant recovery, line-set replacement, electrical panel upgrades, and disposal fees; these can add $200-$3,000 to a job. Replacing a corroded line-set or adding 20 ft of copper refrigerant line typically adds $300-$900.
| Add-On | Typical Cost | When Required |
|---|---|---|
| Refrigerant recharge/recovery | $150-$600 | Older systems, leaks, or retrofit |
| Line-set replacement | $300-$900 | Greater than 20–30 years old or damaged |
| Electrical service upgrade | $800-$3,000 | Insufficient breaker capacity or code update |
| System disposal | $75-$300 | Old unit removal and EPA disposal |
