Typical total cost for a new HVAC system with full ductwork replacement ranges widely based on system size, duct complexity, and region. This article shows realistic pricing ranges, per-unit rates, and the main variables that drive the final cost for new HVAC and ductwork installations.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Split System (HVAC only) | $3,500 | $6,500 | $12,000 | Assumes 2-3 ton, SEER 14-16 |
| Full Duct Replacement (single-story) | $2,000 | $4,500 | $9,000 | $4-$9 per sq ft for 800-2,000 sq ft |
| Complete HVAC + Ducts (typical home) | $6,000 | $11,000 | $21,000 | Includes removal, basic permits |
| Mini-Split Multi-Zone + New Ducts | $7,000 | $13,500 | $28,000 | Per-zone pricing affects total |

Average Total Price for Replacing HVAC and Ductwork in a Typical Home
For a 1,600-2,200 sq ft suburban single-family home, buyers usually pay $9,000-$14,000 for a new central air handler and condenser plus full duct replacement. Average combined price is about $11,000 for mid-efficiency equipment and standard sheet-metal ducts.
Assumptions: Midwest labor rates, 3-ton system, average attic access, standard single-family layout.
Cost Breakdown: Materials, Labor, Equipment, and Disposal
Major line items explain most of the quote differences; contractors commonly itemize these categories. Expect materials and labor to be the two largest shares of the total estimate.
| Materials | Labor | Equipment | Delivery/Disposal | Permits |
|---|---|---|---|---|
| $2,000-$6,000 (coil, condenser, furnace/air handler) | $1,800-$5,500 () | $500-$2,000 (tools, lifts, rigging) | $150-$800 (old unit disposal, duct haul) | $100-$600 (local) |
How Duct Type and Square Footage Change the Price
Material and installation method drive ductwork cost: fiberglass or flex runs cost less than custom sheet-metal trunks. Expect $4-$9 per sq ft for full replacement; 1,000 sq ft at $4-$9 equals $4,000-$9,000.
Numeric thresholds: sealed sheet-metal trunks for homes over 2,000 sq ft often start at $6,000; short-run flex-only installs under 800 sq ft can be under $2,500.

System Size and Efficiency Ratings That Affect Quotes
System capacity and SEER rating directly increase equipment cost and sometimes labor complexity. Range example: 2.0-2.5 ton ($3,500-$6,000), 3.0-3.5 ton ($4,500-$8,000), 4.0+ ton ($6,500-$12,000) depending on SEER.
Higher SEER (16-20) adds $1,000-$4,000 to equipment price compared with baseline SEER 14-15 units.
Practical Ways To Reduce the Price of New HVAC and Ductwork
Control scope and timing to lower bids: retain existing ducts where feasible, schedule installations off-peak, and accept mid-tier efficiency. Removing optional upgrades and keeping job access simple can cut 10%-30% off typical quotes.
Other tactics: get three detailed quotes, do minor prep (clear attic access), and avoid weekend or emergency scheduling to reduce labor markups.
Regional Price Differences and What To Budget by Market
Prices vary by region: urban Northeast/West Coast contractors typically charge 10%-25% more than Midwest/South. Budget adjustments: add 15% for coastal metro areas, subtract 10% for rural or lower-cost interior regions.
| Region | Typical Adjustment | Example Avg Total for Typical Job |
|---|---|---|
| Midwest/South | -10% | $9,900 (baseline $11,000) |
| Coastal Metro | +15% | $12,650 |
| Mountain/Rural | -5% to 0% | $10,450 |
Common Add-Ons, Time, and Labor That Raise the Final Bill
Additional work often billed separately includes asbestos/insulation removal, structural framing, extended refrigerant line sets, and zoning controls. Pay attention to listed line items for these extras—zoning dampers cost $150-$450 per zone installed.

Typical crew/time: 2-4 crew members, 8-20 hours for combined HVAC plus duct replacement on an average home; expect labor rates of $75-$125 per hour depending on location.
Real-World Quote Examples With Specs and Totals
Example A: 1,600 sq ft, 3-ton SEER 14 split system + flex ducts: $6,800 total (equipment $3,700, ducts $2,200, labor $900). This is a lower-cost, basic replacement scenario.
Example B: 2,200 sq ft, 3.5-ton SEER 16 unit + sealed sheet-metal trunking: $13,400 total (equipment $6,800, ducts $4,800, labor $1,800). This represents mid-range efficiency and higher duct quality.
Example C: 2,800 sq ft, 4-ton high-SEER variable-speed system + full custom ductwork + zoning: $22,500 total (premium equipment and complexity drive the high end). High-end installs often add $4,000-$7,000 for zoning and custom trunks.
