How much does air duct replacement cost for a typical home?

Air duct replacement cost for a typical home varies by design and is confirmed only after an in‑home inspection of your duct layout and access points. The biggest price drivers are total duct length and how easy it is to reach runs in attics, crawlspaces, or finished ceilings.

Our technicians regularly evaluate ducts as part of complete HVAC and indoor‑air‑quality solutions across Northern Virginia, so estimates reflect correct sizing, airflow, and commissioning. Many homes don’t need full replacement; sealing, targeted repairs, or cleaning within a maintenance plan may solve comfort or air‑quality concerns, while crushed, mold‑contaminated, or undersized ducts often justify replacement. Parrish Services backs HVAC work with warranties and documents service in a cloud‑based app.

Expect your estimate to account for:

• Number of supply/return runs and total linear feet
• Material choice and insulation (flex vs. sheet metal, R‑value)
• Access complexity and any needed ceiling or finish work
• Airflow balancing, pressure testing, and applicable code/permit requirements

Schedule a professional evaluation to map the system, verify sizing, and provide a clear, itemized quote.
