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

Air duct replacement cost for a typical home is not a single set price and is confirmed only after an on-site inspection. Pricing reflects labor, materials, and the scope of changes to your HVAC airflow and layout.

Our EPA-certified team replaces ductwork in homes across the Beverly Hills area with attention to sizing, sealing, and cleanliness. When ducts are structurally sound, repair or sealing may be more practical; full replacement makes sense when ducts are deteriorated, contaminated with mold, or poorly designed. A small but important detail we check is keeping diameters consistent so airflow stays balanced from room to room. Financing is available.

What most affects price:

• Total duct length and number of runs to replace
• Material and insulation type (flex vs. metal, R-value)
• Access conditions (attic, crawlspace, in-wall) and required labor
• Added components or upgrades (plenums, registers, IAQ add-ons)
