Homeowners typically see total prices for new ductwork range from $2,500 to $10,000 depending on home size, duct type, and installation scope. The main cost drivers include duct material, linear footage, system type (single-zone vs multi-zone), accessibility, and labor. This article breaks down exact price ranges, component costs, and ways to control expenses for new ductwork.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-house ductwork (avg 1,200–2,000 ft) | $2,500 | $5,000 | $10,000 | Typical mid-size home, standard materials |
| Per linear foot (flex duct) | $2.50 | $4.50 | $7.00 | Includes fittings and minimal labor |
| Per linear foot (rigid metal) | $6.00 | $9.50 | $15.00 | Higher durability, smoother airflow |
| Labor (sheet metal crew, 1–2 people, days) | $1,200 | $3,000 | $5,500 | Assumes normal attic or crawlspace access |
| Materials (metal, insulation, duct tape) | $500 | $2,000 | $3,500 | Includes lathing, sealants, insulation |
| Testing and balancing | $100 | $300 | $800 | Post-install airflow tuning |
| Permits and inspections | $0 | $300 | $1,000 | Region-dependent |
| Delivery/ disposal | $0 | $200 | $800 | Removal of old ductwork if needed |
Assumptions: Midwest labor rates, standard 6-inch to 12-inch duct sizes, single-story home with attic access, no structural changes.
Cost components that shape a ductwork quote
Material costs dominate the price, with flexible duct being the most affordable option and rigid metal ducts offering the best efficiency. For 1,000 linear feet, flex duct can run around $2.50–$7.00 per ft, while rigid metal duct often lands in the $6.00–$15.00 per ft range. The choice affects airflow, leak potential, and long-term energy use.
Labor and installation covers crew time, rigging, and fitment around joists and obstacles. In many markets, a two-person crew may bill 6–14 hours for a typical 1,200–1,800 ft project, translating to roughly $1,200–$3,000 in labor. Access issues (attic crawlspaces, tight corners) can push costs higher.
System type and scope matter: single-zone duct layouts for one thermostat vs multi-zone systems with dampers, plus returns, fresh air intakes, and rerouting, raise both material and labor needs. A basic retrofit in a 1,500 sq ft home sits near the lower end, while full replacement in a larger home climbs toward the high end.
Assumptions: Standard attic access, no major structural changes, typical home with existing HVAC components.
How duct type affects your price range
Flexible ducts are versatile and cheapest upfront but may incur higher airflow losses over time. Rigid metal ducts cost more initially but often deliver lower energy use and fewer leaks. In new construction or major renovations, hybrid systems using rigid trunks with flexible branches balance cost and performance. For a mid-size home, expect: flex duct around $2.50–$7.00 per ft; rigid duct around $6.00–$15.00 per ft.
Regional weather and climate influence material choices and labor because humidity, insulation needs, and long-run lengths vary by locale, altering pricing.
Key quantity driver: ductwork length and zones
The total length of duct runs and the number of zones are primary cost drivers. A 1,200–1,500 ft, single-zone replacement is typically $3,000–$7,000, while a 2,000–3,000 ft multi-zone install can exceed $8,000 and reach $12,000 in larger homes.
Assumptions: Homes with standard ceiling heights and no solar or exotic venting systems.
Regional price variations you should expect
Prices vary by region due to labor and permit costs. Coastal cities and high-demand markets may see a 10–20% premium over national averages, while rural areas can be 5–15% lower. A midwest example for 1,300 ft in a standard attic might land at $3,500–$6,000.
Figure ranges reflect typical local factors like labor rates and access.
Labor hours and crew size you’ll likely see
Most ductwork projects use a two-person crew for 6–14 hours on a mid-size home. In complex basements or tight crawlspaces, 2–3 additional hours per 100 ft can occur, adding $150–$500 in labor. A straightforward 1,500 ft install often hits $2,000–$5,000 in labor alone.
Formula: labor hours × hourly rate is a common calculation in bids.
What drives price besides length and type
Access, existing HVAC components, and required duct sealing and balancing play a big role. If walls must be opened or joists cut, or if returns must be relocated, expect a noticeable price uptick. Insulation wrap or inner liners can add $0.50–$2.00 per foot, depending on material.
Assumptions: Normal attic or crawlspace access; no custom architectural work.
Balancing, testing, and warranty implications
Airflow balancing after install costs around $100–$800 depending on home size and number of zones. A 5-year warranty on workmanship is common; extended warranties may add 1–2% of the project price.
Warranty coverage often reflects materials and installation quality.
Cost-saving strategies for new duct systems
Strategies include limiting scope to essential runs, choosing mid-range materials, batching multiple small jobs to save on labor, and scheduling during off-peak seasons. Bundling duct sealing with the installation can save 5–15% compared with separate visits.
Smart planning and comparison shopping are key to controlling the bottom line.
Example quotes to illustrate real-world pricing
Real-world bids vary by home, but three sample scenarios show typical ranges:
- 1,100 ft flex-only retrofit in a 1-story home: $2,800–$4,800
- 1,400 ft hybrid system with rigid trunks and flex branches: $5,000–$8,500
- 2,000 ft full replacement in a two-story home: $9,000–$12,000
Notes: Quotes assume standard attic access, no major structural work, and standard insulation materials.
Choosing between DIY vs. professional ductwork installation
DIY ductwork is generally discouraged due to leakage risks and code requirements. Professional installation ensures sealed joints, proper sizing, and airflow balancing. For most homes, the cost premium for professional work reflects better efficiency, comfort, and code compliance.
Costs rise if permits, inspections, or rework are required.
