Ductwork replacement and design
Ducts usually last 20–25 years. Replace them when the flex jacket is brittle or torn, the system was undersized from the start, or you're installing new equipment that needs more airflow. A Manual D design sizes each run so every room gets the air it needs.

Many 1990s and 2000s valley homes were built with the minimum duct sizing. A new high-efficiency system on old, restrictive ducts can be noisy and fall short of its rated efficiency.
Newer duct systems can also be buried in attic insulation or moved into conditioned space during a remodel.

FAQ
Ductwork Replacement & Design questions
Should I replace ducts with a new AC?+
Not always. If the ducts are sized correctly and in good shape, keep them. If static pressure is high or the ducts are failing, it's cheaper to do both at once.
