Understanding Ductwork Costs for Construction Professionals
In 2025, the cost of residential ductwork installation ranges from $11 to $19 per linear foot, with high-humidity areas reaching $22-$25. Renovations can exceed $30 due to additional complexities. For construction professionals, understanding these costs is crucial for accurate budgeting and project planning.
What Influences Ductwork Costs?
Material, Labor, and Waste
Each linear foot price includes:
- Sheet-metal or flex duct sizes as per code
- Connectors, hangers, mastic, insulation, dampers, and fasteners
- Skilled labor for installation
- Standard waste factor based on jobsite conditions
Real-time updates from suppliers ensure accurate pricing.
Key Cost Drivers
- Duct Diameter: Larger diameters increase costs
- Insulation Rating: Higher ratings can increase material costs by 10-15%
- Layout Complexity: More elbows mean more labor
- Accessibility: Difficult areas increase labor costs
- Regional Labor Rates: Local wage data affects estimates
