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

Air duct replacement cost for a typical home varies by layout, materials, and how accessible the ducts are, and final pricing is confirmed after an on-site inspection. Most costs are driven by how much duct must be replaced and whether it runs through tight spaces like crawlspaces or finished ceilings.

We provide straightforward, upfront pricing with clear options before any work begins. In many homes, sealing leaky ducts or replacing only failing sections restores comfort without a full system swap; leaky ductwork can reduce efficiency by up to 30%, and sealing can potentially reduce energy expenses by up to 20%. We handle these projects regularly in the Hopedale area. A tech-level check helps decide whether to repair, seal, or replace; if rooms only struggle at the far ends, we often swap a few runs and seal the trunk instead of replacing everything. Install or replacement work includes a 2-year warranty (4 years for Priority Plan members).

When you compare quotes, look for:

• Material choice (flex vs. metal) and insulation specs
• Number of supply/return runs and register changes
• Code-driven upgrades (supports, fire-stopping) and airflow balancing

Ask for a duct-leakage test and airflow measurement before you commit.
