Understanding Air Conditioning Ductwork Cost in Residential Construction

For construction professionals, understanding the cost of air conditioning ductwork is crucial for accurate project budgeting. As of 2025, the cost for ductwork installation ranges from $2,800 to $6,000 for an average 2,000 sq ft home. Factors such as home size, material selection, and local labor rates significantly influence these costs. CountBricks provides precise estimates using AI-driven tools, ensuring projects remain on budget and on schedule.

Why Ductwork Prices Vary

• Home size and layout: Larger homes require more extensive duct systems.

• Material selection: Options like galvanized steel and flexible ducting have different costs.

• Accessibility: Installation in crawl spaces or attics can increase labor costs.

• Energy code requirements: Compliance with higher standards can raise costs by 5-15%.

• Local labor market: Urban areas may have higher labor costs compared to suburban regions.

Average Residential Ductwork Cost Benchmarks

Current benchmarks indicate:

  • $12–$20 per linear foot for flexible duct in new construction
  • $18–$30 per linear foot for sheet-metal trunk lines
  • $2,800–$6,000 total for an average 2,000 sq ft home

Projects outside these ranges may involve unique requirements such as historic properties or multi-zone systems. Visit CountBricks.com for more detailed estimates.

Breaking Down the Cost Components

1. Materials (35–45%) – Includes duct sections, fittings, and insulation.
