Furnaces and traditional HVAC units need a controlled path in the form of air ducts to distribute heated or chilled air throughout your house. Usually, these air ducts are constructed using sheet metal, but sometimes heatproof and rigid materials like insulated plastic and fiberglass are also used. No matter what construction material is used to build the ductwork, the heart of the system is always the plenum. Now you might be wondering – what is a plenum?
In this article, we will tell you everything you need to know about the plenum, including the types of plenum boxes, and their importance in the efficient functioning of your furnace.

What is a Plenum?
Your HVAC system functions best when there is optimal air distribution and airflow. The plenum is what helps in achieving optimal air distribution in your duct system. A plenum is essentially a chamber, air space, or compartment that is filled with air that is then distributed throughout your home. A large blower, which is fixed below, above, or adjacent to the plenum fills this chamber with hot air, which is then distributed through the duct system, providing warm air to your rooms.
Plenum installation is excellent for:
- Increasing the airflow in your home or building
- Improving air quality
- Reducing humidity levels
- Lowering the energy costs
Plenum Types
- Supply Plenum Box: This plenum box is directly connected to the supply outlet of your furnace or HVAC unit. It receives the heated/cooled air directly from the furnace/HVAC system. This air is then distributed through the duct system and circulated throughout the house.
- Return Plenum Box: This chamber is connected to the return vents of your HVAC unit or furnace. It receives the air from these vents, distributing it through your ductwork back to the furnace/HVAC unit to be heated/cooled again. Before the used air enters the return plenum, it passes through a filter. This ensures that the air remains clean before reentering your furnace/HVAC unit.
Plenum Installation: Why Does It Matter?
When learning what a plenum is, it’s also important to understand how incorrect installation of the plenum affects your furnace/HVAC system. As we have already stated, the plenum is the heart of the air distribution system in your home. If the plenum is not connected efficiently, it can lead to malfunctioning heat exchange and even frozen coils. This is why it is always best to trust professionals with the furnace plenum installation.
With professional installation, you can ensure:
- Lesser problems with airflow
- Better air distribution
- Reduced operational costs
- Improved air quality indoors
- Increased lifespan for the furnace/HVAC system
