Most U.S. homeowners pay $5,000-$12,500 to replace both a central air HVAC system and a gas or electric furnace; the final cost depends on system size, efficiency, ductwork, and labor. This article lists new HVAC and furnace cost ranges, per‑ton and per‑BTU pricing, and the main items that drive quotes so buyers can estimate realistic budgets.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Complete HVAC + Furnace Install | $4,500 | $8,500 | $18,000 | Assumptions: 2.5‑4 ton system, 80,000–120,000 BTU furnace, standard ducts, suburban installer. |
| Air Conditioner (condensing unit) | $2,000 | $4,000 | $7,000 | $800-$2,000 per ton depending on SEER and brand. |
| Furnace (forced‑air) | $1,200 | $3,200 | $6,500 | $600-$2,000 per 100k BTU for basic to high‑efficiency models. |
| Ductwork Repair/Replacement | $500 | $3,500 | $10,000 | Per home; large homes need full replacement. |

Total Price for Installing a New HVAC System and Furnace
Typical total price for a full HVAC and furnace replacement runs $4,500-$18,000, with an average around $8,500 for a 2.5–4 ton split system paired with a 80k–120k BTU furnace. This average assumes normal access, no major duct replacement, and mid‑range efficiency (13–16 SEER, 80–95% AFUE).
Assumptions: Midwest labor rates, standard materials, normal access.
Breakdown of Material, Labor, Equipment, and Permits
| Component | Low | Average | High |
|---|---|---|---|
| Materials (units, coils, furnace) | $1,800 | $5,200 | $12,000 |
| Labor (installation) | $800 | $2,800 | $6,000 |
| Equipment (rigging, lift, specialty) | $150 | $600 | $2,000 |
| Permits & Inspections | $50 | $300 | $1,200 |
| Delivery / Disposal | $75 | $350 | $900 |
Labor is commonly 20–35% of the total quote for standard installs; factor more for difficult access or two‑story homes.
How Size, SEER, and Furnace BTU Change the Final Quote
Increasing system size or efficiency raises costs predictably: a 1‑ton increase adds roughly $800-$2,000 to AC unit price; moving from 14 SEER to 18 SEER adds about $1,000-$3,000. Furnace sizing matters: 80k BTU furnaces often cost $1,200-$2,500, while 120k+ BTU high‑efficiency units run $3,000-$6,500.
Numeric thresholds: choose 2–3 ton for ~1,200–1,800 sq ft, 3–4 ton for 1,800–3,000 sq ft; consider 13–16 SEER for budget installs, 17+ SEER for long‑term savings.

Practical Ways To Cut New HVAC and Furnace Price
Control scope: keep duct layout and locations the same, opt for 14–15 SEER instead of top tier, and schedule installations in shoulder seasons to lower labor premiums. Simple prep work by the homeowner—clearing attic access, labeling vents, and moving obstacles—can reduce crew time and save $150-$500.
Other cost decisions: accept standard warranty, bundle AC+furnace purchase with same contractor, and repair ducts rather than replace when feasible.
Price Differences by U.S. Region and Climate Zone
Region affects both labor and system sizing: coastal and Northeastern cities typically add 10–25% to average quotes; Southern states may need higher‑capacity systems increasing unit cost by 5–15%. Expect $700-$1,500 higher average price in high‑cost metro areas versus rural Midwest.
| Region | Average Install | Delta vs Midwest |
|---|---|---|
| Midwest | $7,500 | Baseline |
| Northeast / Coastal | $8,500-$9,500 | +10–25% |
| South (hot climate) | $8,000-$10,000 | +5–20% (larger AC) |
| West / Mountain | $8,500-$11,000 | +10–30% |
Typical Install Job Examples With Specs and Pricing
| Scenario | Specs | Labor Hours | Total Price |
|---|---|---|---|
| Basic 2.5‑ton Split + 80k BTU | 14 SEER, 80% AFUE, reuse ducts | 10–14 | $4,500-$6,500 |
| Mid‑Range 3.5‑ton + 95k BTU | 16 SEER, 95% AFUE, minor duct repairs | 14–22 | $7,000-$10,500 |
| High‑Efficiency 4.5‑ton + 120k BTU | 18+ SEER, 98% AFUE, new ducts | 20–36 | $12,000-$18,000 |
These examples show how equipment grade, ductwork scope, and labor hours move totals across realistic project types.
Common Add‑Ons, Removal Fees, and Permit Charges That Add Up
Expect extra charges for coil changeouts ($800-$2,000), full duct replacement ($3,000-$10,000), electrical upgrades ($500-$2,500), and refrigerant recovery or recharge ($150-$700). Removal and disposal of old equipment typically adds $75-$400; permits add $50-$1,200 depending on local rules.
Plan for a 5–10% contingency on top of contractor quotes to cover unforeseen issues like hidden duct damage or required electrical work.
