On average, the cost ranges from $2,000 to $5,000 for a small to medium-sized home. However, duct replacement can run as low as $1,400 for smaller homes and as high as $9,000 for larger homes. Your specific cost depends on your home’s size, layout, and the type of ductwork materials needed. We provide upfront pricing with no hidden fees. Every estimate includes materials, labor, permits, and cleanup. You’ll know the total cost before we start work, not after we’re halfway done. Financing options are available to help spread the cost over time. The energy savings from properly installed ductwork often offset monthly payments, making the upgrade cash-flow positive from the start.
