Definition
The network of channels that distributes heated and cooled air through your home. Leaky or poorly designed ducts can waste 20–30% of your system's output.
Why this matters for your home
Ductwork is the supply-and-return network that carries conditioned air through your home. Good duct design balances airflow, sizes each run correctly, and seals every joint; poor design starves some rooms while overworking the blower.
Leaky or undersized ducts can waste 20–30% of what your equipment produces — air you paid to heat or cool escaping into attics and crawlspaces. Before recommending a bigger furnace or AC, we check whether sealing and balancing your existing ducts would solve the comfort problem for less.
