Furnace Plenum Parts

A HVAC plenum provides separate space for air circulation. In a furnace system, the plenum is a compartment located between the furnace and the ductwork that distributes the heated air to the various rooms of a building. Furnace Plenum Parts are typically made of sheet metal and connected to the furnace with a large metal collar that is sealed to the furnace with mastic to prevent air leaks.

The plenum serves several important functions in a furnace system. It helps to reduce the noise created by the furnace by muffling the sound of the blower. The HVAC plenum also serves as a junction point for the ductwork, providing a place where the ducts can be connected and disconnected for maintenance or repairs.

Some modern furnace systems have built-in plenums and others use the existing structure such as an attic or crawl space as the plenum.
