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

Air duct replacement cost for a typical home is determined only after an on-site inspection because homes differ in layout, condition, and code requirements. A licensed technician evaluates the existing ducts, confirms system sizing, and designs the replacement so airflow and comfort improve. In our Demotte area work, we often find that correcting past routing or balancing adds labor but prevents hot-and-cold spots later. We provide upfront pricing before any work begins.

Expect pricing to reflect:

• Total duct length and number of runs to replace
• Material and insulation choice (metal, flex, or ductboard)
• Access limits and any drywall or ceiling removal and patching
• Add-ons like sealing, airflow balancing, new boots/registers, and required permits
