Professional Duct Services in the Greater Boise Area

Air duct replacement cost for a typical home varies and is only confirmed after an on-site inspection. Most of the price comes from labor to remove old ducts and install new runs through attics or crawlspaces.

We regularly replace ductwork in the Treasure Valley and tailor layouts to local home styles and seasonal comfort. A technician will check duct condition, measure airflow needs, and evaluate access limits before quoting. Material selection (flex, sheet metal, or combinations) and redesigning return air can change both cost and comfort. When leaks are limited to a few sections, repair is often the most cost‑effective choice; full replacement makes sense when damage is widespread. We offer free estimates and free second opinions.

• Signs pointing to replacement: crushed or disconnected runs, widespread leaks, severe rust, or contamination after water damage.
• Factors that raise cost: tight crawlspaces or attics, rerouting for better airflow, and adding larger return ducts.
• What happens next: sizing calculations, scope options, and an itemized quote covering removal, new ducts, and airflow balancing.
