Why do we use plenum in HVAC?
Plenum boxes are usually situated on either side of the fan or heat exchanger and have the important function of bringing in, distributing, and removing air. They are the air’s first stop after being heated or cooled and its last stop before going back into your AC, heat pump, or furnace.
What are main ducts?
The duct pipes and trunks are the primary channels that provide a path for heated or cooled air to blow throughout your home. The duct pipes branch out from the duct trunk to the different rooms in your house. The duct trunk is the main duct from the furnace, usually made of steel.
What is a plenum and where would I find one?
A plenum is an air-distribution box attached directly to the supply outlet of the HVAC equipment that heats or cools the air to make the house comfortable. The ductwork that distributes the heated or cooled air to individual rooms of the house connects to the plenum.
What size does flex duct come in?
Is metal ductwork better than flex ducts?
Flex ducts are better for existing trunk-and-branch heating and cooling systems. This is because they’re more versatile and flexible. Metal ducts are more rigid due to the nature of steel, making them ideal to build an entire HVAC system.

What is rigid ductwork?
Rigid ductwork is made up of various materials that are then filled with insulation. Unlike flexible ductwork, rigid ductwork doesn’t make loud noises when air passes through it.
