Typical buyers pay between $4,500 and $12,500 to install a new furnace and air conditioner together; the combined cost depends on system size, efficiency, ductwork condition, and local labor rates. This article breaks down new furnace air conditioner cost ranges, per-unit pricing, and the largest factors that change quotes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete Furnace + AC Install | $4,500 | $8,500 | $12,500 | Assumptions: 2,000 sq ft home, standard ducts, suburban labor. |
| Furnace Only (installed) | $1,800 | $3,800 | $7,000 | Per unit: depends on BTU and AFUE. |
| AC Condenser + Coil (installed) | $2,200 | $4,700 | $8,500 | Per ton: see per-ton ranges below. |
| New Ductwork | $1,000 | $3,500 | $8,000 | Linear ft pricing varies by access. |
What Homeowners Commonly Pay For A New Furnace And AC
Combined installations for an average 1,800–2,400 sq ft U.S. home typically range $4,500-$12,500 with $8,500 as a median. Average split: furnace $1,800-$3,800; AC $2,200-$4,700 (installed).
Assumptions: standard 2.5-ton AC for 1,800 sq ft, 80,000–100,000 BTU furnace, mid-efficiency models, normal attic/crawl access, suburban labor.
Line-Item Quote Breakdown: Materials, Labor, Equipment, Permits
| Cost Component | Low | Average | High |
|---|---|---|---|
| Materials (units, coils, controls) | $1,800 | $4,200 | $8,000 |
| Labor (installation crew) | $1,200 | $2,800 | $5,000 |
| Equipment (crane, lift rental) | $0 | $150 | $800 |
| Permits & Inspections | $50 | $300 | $1,000 |
| Delivery/Disposal | $100 | $350 | $900 |
Typical contractor quote is Materials + Labor + Equipment + Permits + Disposal = total installed price.
How System Size And Efficiency Change The Final Quote
System capacity and SEER/AFUE ratings drive large price steps. Examples: upgrading from 2.5-ton to 3.5-ton AC adds roughly $800-$2,200; moving from 14 SEER to 18 SEER adds $1,000-$2,500.
Other numeric drivers: furnace BTU — 60,000 BTU units are often $1,800-$2,500; 120,000 BTU commercial-style furnaces can be $4,000-$7,000. Duct replacement over 200 linear ft typically adds $2,000-$6,000.
Practical Ways To Cut New Furnace And AC Price Without Compromising Safety
Control scope: replace only the minimal components, delay high-efficiency upgrades, and schedule in off-peak seasons. Simple actions can shave $500-$2,000 from a combined quote.
Other cost-saving steps: prepare access (clear attic/garage), bundle furnace+AC with one contractor for a single mobilization fee, and accept manufacturer-standard warranty instead of extended plans when budgets are tight.
Regional Price Differences Across U.S. Markets
Prices vary by region: Northeast and West Coast typically 10%-25% higher than Midwest; rural areas may add travel/minimum charges of $150-$450. Expect Midwest baseline; add 10%-25% in high-cost urban markets.
| Region | Typical Adjustment | Reason |
|---|---|---|
| Midwest | Baseline | Moderate labor and materials |
| Northeast | +10% to +20% | Higher labor, permits |
| West Coast | +15% to +25% | Higher overhead and regulations |
| Rural | ±0% with travel fees | Contractor minimums, travel |
Three Real-World Quote Examples With Specs And Costs
Example A — Smaller home, budget units: 1,400 sq ft, 2.0-ton AC, 80,000 BTU furnace, basic ducts: Materials $2,000; Labor $1,200; Total $4,500.
Example B — Average suburban install: 1,900 sq ft, 2.5-ton 16 SEER, 95,000 BTU 95% AFUE furnace, minor duct sealing: Materials $4,400; Labor $2,200; Total $8,000.
Example C — High-end upgrade: 2,400 sq ft, 3.5-ton 18 SEER, 120,000 BTU 98% modulating furnace, new ducts: Materials $8,000; Labor $4,000; Total $12,500.
Common Add-Ons, Delays, And Fees That Inflate A Quote
Frequent extras include emergency service/rush install fees ($150-$600), refrigerant line set replacement per linear ft ($4-$12 per ft), and code-required gas line upgrades ($500-$2,000). Allow a contingency of 5%-15% for unexpected repairs or access problems.
Scheduling delays during seasonal peaks can also increase labor markup by 10%-20% if contractors are fully booked.
