Duct replacement cost depends on how much of your ductwork needs to be replaced, how accessible your attic is and whether the system needs design changes like added returns. Many homes do not need full replacement: targeted duct repair typically costs $300 to $2,000 and duct sealing $600 to $2,500. We inspect your ducts and give you options in writing.

Why ducts matter in Arizona
Most ducts in Surprise and Sun City West run through attics that get far hotter than the outdoor air in summer. According to ENERGY STAR, a typical home loses about 20 to 30 percent of the air moving through its ducts to leaks and poor connections. In a hot attic, that loss is expensive.
