Where Are Air Ducts in a House?

Basement and Crawlspace: Basements and crawlspaces are a common location for air ducts. These areas provide ample space for installing both supply and return ducts. As they are often accessible, maintenance becomes relatively easier.

Attic: Another prevalent spot for air ducts is the attic. Attics house the main supply ducts responsible for carrying conditioned air to different parts of your house. Attic installations also make it easier to extend ducts to various levels.

Walls: Some homes feature air ducts concealed within interior walls. This strategic placement ensures efficient airflow to different rooms while maintaining aesthetics.

Ceilings: In houses without basements, air ducts may run through the ceilings to ensure effective distribution of air to upper floors. This arrangement is common in multi-story residences.

Under Floors: For homes built on raised foundations, air ducts can be found beneath the floors. These ducts supply conditioned air to rooms situated above the foundation.

Closets: In multi-story homes, closets often house vertical air ducts that serve multiple floors. This arrangement optimizes space while ensuring efficient airflow.
