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

Air duct replacement cost for a typical home varies by system size, layout, materials, and access, and Dawson’s Electric & Air confirms final pricing only after an on‑site evaluation. The biggest cost driver in most homes is the amount of ductwork needed to match airflow to each room. We don’t offer duct cleaning or maintenance at this time, but we do handle ductwork installation and replacement for HVAC systems. Our team often replaces or redesigns ducts to improve comfort and efficiency, and we serve homes throughout the Cary area. One technician insight: upsizing a central return can stabilize room pressures more than adding another small supply run. We stand behind our work with a labor warranty and provide extended warranties to maintenance plan members at no additional charge.

When to expect higher or lower pricing:

• More square footage or added runs increase material and labor
• Tight attics or crawlspaces raise access time
• Rigid metal costs more than flex and may need fabrication
• Redesigns to fix airflow add layout and balancing work
