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

Air duct replacement for a typical home is priced after an on-site evaluation, because the cost depends on home size, system layout, materials, access, and any needed code or design updates. The biggest driver is how much of the existing ductwork must be replaced versus what can be sealed, cleaned, or reused. We inspect your system end to end, diagnose issues, and then present clear options with upfront pricing before work begins, backed by strong warranties. Our team regularly installs and replaces ductwork for homeowners in the Bastrop area.

What most affects your final price and timeline:

• Total duct length and number of supply/return runs
• Material choice (flex vs. metal) and required insulation level
• Attic or crawlspace access and how tight the work area is
• Plenum or air handler modifications and add-ons like sealing, testing, or filtration

If you’re unsure, a technician can confirm whether targeted repair and sealing will meet your comfort and airflow needs before you commit to full replacement. <br/> Updated: 2026-03-12 <br/> Need help in Bastrop, TX? Call (512) 309-0360 or book online.
