Typical buyers pay $5,000-$18,000 for a new HVAC system with new ductwork; final price depends on system size, duct complexity, and labor. This article lists realistic HVAC and ductwork cost ranges and the main drivers that change the quote so buyers can budget accurately for the cost of new HVAC and ductwork.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Split System + New Ducts (2-ton, 1,200-1,800 sq ft) | $5,000 | $10,500 | $18,000 | Includes mid-efficiency equipment, standard metal ducts |
| Heat Pump + New Ducts (2.5-ton, 1,800-2,500 sq ft) | $7,000 | $13,500 | $24,000 | Higher for cold-climate cold-climate sizing and labor |
| Duct Repair/Partial Replacement | $800 | $3,500 | $7,500 | Depends on linear feet and access |
Typical Total Price For Replacing HVAC With New Ductwork
Assumptions: single-family home, standard access, mid-efficiency 13-16 SEER split system, steel ducting.
Most homeowners pay $8,000-$15,000 for a complete HVAC replacement with new ducts for a 1,500–2,000 sq ft home.
Low range $5,000-$7,500: small homes (under 1,200 sq ft), single-stage 13 SEER, minimal new duct runs. Average $8,000-$15,000: 1,200–2,000 sq ft, 2–3 ton equipment, full new metal ducts, basic zoning not included. High range $16,000-$24,000+: large homes, high-efficiency systems, extensive sheet-metal or flex runs, major structural access, or multi-zone setups.
Breaking Down The Quote: Materials, Labor, Equipment, Permits
A typical contractor estimate separates costs into equipment, materials, labor, permits, and disposal so buyers can compare line items.
| Materials | Labor | Equipment | Permits | Delivery/Disposal |
|---|---|---|---|---|
| $800-$4,000 (ducts, insulation, registers) | $1,500-$6,000 | $2,500-$10,000 (furnace/AC/heat pump) | $50-$800 (local) | $100-$600 (old unit haul, scrap) |
How Capacity, Home Size, And Duct Linear Feet Change The Final Price
Key numeric drivers: equipment tonnage, conditioned square footage, and duct linear feet—each has clear price steps.
Equipment tonnage: 1.5–2.0 ton units suit 700–1,200 sq ft; 2.5–3.5 ton for 1,500–2,500 sq ft. Expect $1,200-$2,500 extra per additional ton. Ductwork length: under 100 linear ft often runs $800-$2,000; 100–300 linear ft typically $2,000-$6,000; over 300 linear ft can exceed $7,500. Access complexity: attic or crawl access adds $500-$3,000 depending on insulation and framing.
Where Buyers Can Reduce The Price On HVAC And New Ductwork
Controlling scope, timing, and material choices yields the largest savings without sacrificing function.
Keep existing ducts if they’re in good condition and only need sealing ($300-$1,200) instead of full replacement. Choose mid-efficiency equipment (13–16 SEER) rather than premium (18+ SEER) to save $2,000-$6,000. Schedule replacement in spring or fall to avoid peak-season rush premiums. Get at least three detailed quotes and compare line-item labor hours and duct linear footage to spot padding.
How Region And Climate Affect Pricing Across The U.S.
Regional labor rates and climate requirements change HVAC and ductwork pricing by roughly ±15–35% from national averages.
Urban Northeast and West Coast: add ~15–35% for higher labor and permit costs. Midwest and South: often 5–15% below coastal averages. Cold climates may require larger furnaces or backup heat; plan $1,000-$4,000 more for higher-capacity or cold-climate-rated heat pumps.
Common Add-Ons, Removals, And Site Complications That Raise The Quote
Expect extra fees for asbestos/insulation removal, crawlspace stabilization, and difficult equipment placement.
Asbestos or hazardous material abatement: $800-$4,000. Old unit disconnect and disposal: $100-$600. Long refrigerant or duct runs (over 50 ft): add $300-$1,200 for additional refrigerant, line sets, and labor. Trench or structural modifications to run ducts between floors: $1,000-$6,000 depending on scope.
