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

Air duct replacement for a typical home is quoted after an on-site evaluation because total price depends on duct length, home layout, attic or crawlspace access, material choice, and labor needs. Most costs are driven by how many runs must be replaced and whether new plenums, fittings, or code upgrades are required. We first check if sealing, re-strapping, or replacing a few sections will solve airflow or leakage before recommending a full swap. A common field clue: if light shows through duct seams during a pressure test, replacement often beats patching. We handle duct repairs and replacements across the Boerne area with a practical, fix-what’s-needed approach. Financing options are available, as noted by customers.

When full replacement is more likely:

• Major kinks, crushed or undersized runs causing chronic hot/cold rooms
• High leakage or torn insulation leading to dust or high bills
• Mold, smoke, or pest damage inside ducts
• Old, non-sealed duct systems that fail basic pressure tests

Ask for a written scope with duct sizes, R-value, sealing method, and final test results before you approve work.
