Duct count and home layout
The number of supply runs, returns, rooms and layout changes affects material, labor and the final installation scope.

Ductwork replacement and installation
Airflow the whole home can feel.
Most ductwork repair and replacement projects plan around $3,000–$7,000. Use the estimator to compare a small, medium, or large home before the on-site duct count and condition review.
Simple ductwork cost estimator
Choose the approximate size of the home to see a simple planning range based on roughly $600 per duct.
Home size is only a starting point. Layout, returns, duct type, access, damage and redesign needs determine the final scope.
Call for a ductwork estimateWhat changes the price
The estimator uses roughly $600 per duct for early planning. The final price depends on the actual duct count, condition, access, returns and whether the layout needs correction.
The number of supply runs, returns, rooms and layout changes affects material, labor and the final installation scope.
Torn, disconnected, crushed or poorly insulated ductwork may need targeted repair or replacement rather than cleaning.
Tight access, long runs and difficult installation areas can increase labor beyond the basic per-duct planning amount.
A duct replacement should address room comfort, airflow balance and return-air needs instead of copying a poor layout.
Ductwork installation process
A useful ductwork estimate should explain what needs repair, what needs replacement and why the recommended layout supports better airflow.
Start with home size, uneven rooms, weak airflow, visible damage and whether the project is repair, replacement or a new layout.
The on-site review confirms accessible duct runs, returns, insulation, connections, attic conditions and redesign needs.
The proposal separates targeted work from full replacement and explains what is included before installation begins.

~$600 per duct
Typical full projects run $3,000–$7,000 depending on the home. Damaged, leaking, or undersized ducts get their own plan — priced before any work begins.

Repair, replace, or redesign?
Not every project requires full replacement. The inspection separates isolated damage from system-wide deterioration or layout problems.
Best when only a few accessible runs or connections are damaged and the overall layout still works.
Best when damage, leaks, deteriorated insulation or repeated airflow problems affect much of the duct system.
Best for additions, remodels, new construction or homes where the existing design does not support balanced airflow.

Still unsure? Call usMost residential projects plan around $3,000–$7,000. Using approximately $600 per duct, a small home with 5–7 ducts may plan around $3,000–$4,200, a medium home with 8–10 ducts around $4,800–$6,000, and a large home with 11–14 or more ducts around $6,600–$8,400 or more. Final pricing requires an on-site count and condition review.
No. Home size is an easy starting point, but the actual price depends on duct count, returns, layout, material, access, damage, insulation and whether the system needs redesign. Two homes with the same square footage can require different scopes.
Cleaning addresses dust, odors or buildup inside ductwork that is still structurally usable. Replacement addresses torn, crushed, disconnected, leaking, deteriorated or poorly designed ductwork. An inspection helps determine which service fits the condition.
Sometimes. Targeted repair or replacement may make sense when damage is limited and the remaining layout, insulation and connections are in good condition. Widespread deterioration or airflow problems may justify a larger replacement scope.
More duct runs, additional returns, tight attic access, long runs, damaged insulation, removal work or a redesigned layout can increase material and labor beyond the typical range.
The ranges ($6,000–$17,500 by system size) are honest planning figures that include equipment, labor, old-unit removal, permit and inspection, a hurricane-rated pad, and a 10-year warranty. The exact price comes from a free in-home evaluation with a load calculation — in writing, before you decide.

Ductwork repair or replacement runs about $600 per duct, with typical full projects between $3,000 and $7,000 depending on the home. It is always scoped and priced as its own written plan before any work begins.
