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

Air duct replacement cost for a typical home is determined after an on-site evaluation because price depends on system design, materials, and access conditions. The biggest driver is the size and layout of the duct system that must be redesigned and balanced for proper airflow. Streamline designs ducts using detailed home analysis and load calculations, installs premium materials, seals to cut energy loss, and verifies results with airflow testing; final pricing is confirmed after inspection. Free installation estimates and financing are available for qualified projects. Our team serves the Wake Forest area and tailors each replacement to the home, not a template.

When we price a replacement, we look at:

• Total duct length, number of runs, and registers
• Material choice (metal vs flex) and required insulation/sealing
• Attic or crawlspace access and obstacles
• Adding returns, zoning, or ventilation upgrades
• Code updates and final testing/balancing scope

An in-home evaluation is the right next step to get an accurate, all-in quote.
