Buyers typically pay $7,000-$14,000 to install a new gas furnace and matched air conditioning system; the final price depends on unit size, efficiency, ductwork, and local labor. This article focuses on the cost of a new gas furnace and AC unit with clear low-average-high ranges and practical assumptions for U.S. homeowners.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Full Furnace + AC Install (complete) | $5,500 | $9,500 | $16,000 | Assumptions: 2–3 ton AC, 80k–100k BTU furnace, standard single-family home, normal ducts. |
| Furnace Only (unit + install) | $2,500 | $5,000 | $9,000 | Assumptions: mid-efficiency furnace, standard flue, no major ductwork. |
| AC Condenser Only (unit + install) | $2,500 | $4,500 | $8,000 | Assumptions: 2–3 ton condenser, matched coil, includes refrigerant charge. |

Total Cost to Install a New Gas Furnace and AC Unit
Typical installed prices run $7,000-$14,000 for a matched gas furnace and central AC in a median-size U.S. home.
Low-end installs ($5,500-$7,500) use economy furnaces (80% AFUE) and 2–2.5 ton ACs with minimal duct changes. Average jobs ($8,000-$11,000) use mid-efficiency furnaces (90%–95% AFUE) and 2.5–3 ton ACs with minor duct sealing. High-end installs ($12,000-$16,000+) use high-efficiency furnaces (95%+ AFUE), 3–4 ton or variable-speed ACs, extensive ductwork or multi-zone systems.
Assumptions: Typical 1,800–2,400 sq ft home, standard attic/basement access, one-story or two-story with central duct system.
Material, Labor, Equipment, Permits, Delivery/Disposal Table
Breakdown helps compare contractor quotes and spot where savings are possible.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $3,000-$8,000 (furnace+$condensers+coil) | $1,500-$4,500 () | $200-$1,200 (lift, crane if needed) | $50-$600 (local) | $150-$600 (old unit haul, refrigerant recovery) |
How Unit Size, Efficiency Rating, and Ductwork Raise or Lower Quotes
Three dominant variables are equipment capacity (tons/BTU), efficiency (SEER/AFUE), and duct condition—each can change price by hundreds to thousands of dollars.

Capacity: 2.0–2.5 ton systems fit smaller homes; upgrading to 3.5–4.0 ton adds $700-$2,000 for the condenser and matching coil. Efficiency: moving from 13 SEER/80% AFUE to 16–20 SEER/95%+ AFUE typically increases equipment cost by $1,200-$4,000. Ductwork: minor sealing and insulation $300-$1,200; full replacement or major resizing $2,000-$7,000.
Other numeric thresholds: line set runs over 40–50 ft add $150-$600; complex venting or high-efficiency furnace categories requiring sealed combustion can add $300-$1,000 for additional materials and labor.
Practical Ways To Reduce the Price for Furnaces and AC Units
Control scope, timing, and specifications: simple choices like standard-efficiency units, off-season scheduling, and preparing the site reduce the installed price substantially.
Recommendations: schedule installs in spring or fall to avoid peak HVAC demand; accept a matched mid-efficiency package rather than top-tier variable-speed equipment; clear attic/basement access and remove old equipment before arrival to avoid lift-time delays. Get at least three itemized quotes and compare line-by-line for materials, labor hours, and warranty terms.
Regional Price Differences Across The U.S. and What To Expect
Prices vary: expect 10%–25% higher labor/materials in high-cost metro areas vs. lower rates in rural and some Midwest/South regions.
Example deltas: Northeast/West Coast metro areas: +10%–25% versus national average. Midwest and parts of the South: -5%–10%. Rural installs may have lower hourly rates but higher travel fees or minimum charges. Adjust the averages above by these factors when budgeting.

Typical Labor Time, Crew Size, and Scheduling For a Full Replace
A standard furnace and AC swap usually takes 8–18 hours with a 2–3 person crew; complex jobs can take 2–4 days.
Simple swap: 8–12 hours, 2 techs, common when ducts and electrical are ready. Moderate job: 12–24 hours, 2–3 techs, includes minor duct sealing and condensate/run work. Major job: 1–4 days, larger crew, when new ducts, gas line upgrades, or roof crane lifts are needed. Typical labor rates: $75-$125 per hour depending on region and crew certification.
Common Add-Ons, Removal Fees, and Permit Costs That Increase Final Price
Expect extra charges for refrigerant recovery, old-unit disposal, permit upgrades, and electrical or gas work.
| Add-On | Typical Range | When It Applies |
|---|---|---|
| Refrigerant recovery | $75-$250 | Replacing condenser or removing old unit |
| Old unit haul and disposal | $100-$400 | Contractor removal of existing equipment |
| Permit & inspection | $50-$600 | Local codes, furnace type, and value of work |
| Gas line upgrade | $300-$1,200 | Higher-BTU furnace or long run |
| Electrical subpanel or disconnect | $200-$1,500 | Insufficient existing electrical capacity |
