Air duct replacement cost for a typical home varies and is only confirmed after an in‑home inspection. Most of the price comes from how much duct must be replaced versus repaired, the condition of existing ducts, and the labor needed to access tight spaces. Our team regularly handles these projects across the Davenport area and provides upfront pricing before any work begins. In many homes, replacing a few damaged runs and sealing the rest fixes comfort issues; full replacement is better when ducts are undersized, crushed, or badly deteriorated.
Expect price to reflect these factors:
- Total number of runs and registers being replaced or added
- Material and spec: flex, sheet metal, or ductboard, plus insulation R‑value
- Access and difficulty: tight attics, low crawlspaces, or multi‑story routing
- Scope items: new plenums, boots, dampers, sealing, and air balancing

To seal a leaking air duct and improve HVAC efficiency, apply HVAC mastic or UL 181–rated foil tape to joints and seams, not cloth duct tape. Most leaks come from loose connections at plenums, boots, and take‑offs that let conditioned air escape and pull dust in. Small, reachable gaps are usually a simple repair, while crushed flex, torn liners, or widespread leaks point to professional service or section replacement. Our team frequently seals and tests ducts in the Davenport area and sees biggest gains at attic connections. Pros brush mastic into the joint and reinforce larger gaps with mesh so the seal flexes without cracking.
For a basic DIY seal, follow these steps:
- Turn the HVAC off and access ducts safely.
- Find leaks by feel or smoke stick, then mark them.
- Clean and dry surfaces; seal with mastic or UL 181 foil tape only.
- Seal boot-to-drywall gaps and reinsulate after sealing.
If you suspect major leakage, schedule a duct pressure test to confirm repairs.
