Air duct replacement cost for a typical home is confirmed only after an in-home evaluation. Many homes can avoid full replacement if leaks are sealed or a few sections are replaced; full replacement is advised when ducts are rusted, crushed, contaminated, or the layout cannot deliver proper airflow. Our technicians design new duct systems with careful measurements and calculations. One field truth: when several rooms run weak, correcting trunk sizing fixes more than adding extra branches. We see these patterns often in Central Indiana homes.
Key factors that move price up or down:
- Home size/tonnage and the count of supply and return runs
- Duct material and insulation level (metal, rigid, or flex with proper R-value)
- Access conditions and run lengths (attic, crawlspace, or finished basement)
- Needed upgrades like balancing dampers, new registers, or IAQ add-ons
Schedule an evaluation to receive a written scope and exact price before any work begins.
