Average HVAC Ductwork Price For A 2,000 Sq Ft House
A typical full duct replacement for a 2,000 sq ft single-family home usually costs $3,500-$10,000, with $7,500 as a common average.
Assumptions: two-story house, 8-10 supply/return outlets, standard sheet metal or insulated flex runs, normal attic access, no major framing changes. Higher-end materials or complex zoning increases price.

Examples with numeric thresholds: adding more than 200 linear ft of ductwork typically raises labor and material by 25%-50%; switching from insulated flex to fabricated sheet metal increases material cost by $2-$6 per linear ft.
Other thresholds: attic or crawlspace access that requires >10-12 hours of extra labor often adds $600-$1,500; including 3 or more HVAC zones (dampers and controls) adds $800-$2,500.
Practical Ways To Cut HVAC Duct Work Price
Control scope and simplify materials to reduce cost without sacrificing core performance.
- Repair and seal leaks instead of full replacement when leakage is under 20% (typically $150-$800).
- Use insulated flex for short, accessible runs at $3-$7 per linear ft instead of custom sheet metal at $10-$25 per linear ft.
- Bundle with HVAC system service or replacement to negotiate labor savings.
- Schedule work in off-peak seasons (spring/fall) to avoid rush premiums.
Typical Crew Size, Labor Hours, And Installation Time For Duct Projects
Most residential duct jobs use a 2-3 person crew and take 1-5 days depending on scope.
| Job Type | Crew Size | Labor Hours | Typical Duration |
|---|---|---|---|
| Minor repair/sealing | 1-2 | 2-8 | 2-8 hours |
| Partial replacement (several runs) | 2-3 | 12-40 | 1-2 days |
| Full replacement (2,000 sq ft) | 2-4 | 24-80 | 2-5 days |
Assumptions: standard access, no structural alterations. Labor rates often $75-$125 per hour per technician.
