Supply ducts blow warm or cool air to an area inside a home. Supply vents often have dampers to control the flow, called registers . Supply registers will often be installed near windows or doors to better counteract the loss of heat or cold, and two supply registers may be installed in larger rooms to evenly distribute the HVAC air.
What is flex duct?

Where does HVAC get its air?
Contrary to popular belief, HVAC systems get their air from inside the building. Return ducts extract air from the living spaces back to the HVAC unit, feeding either your furnace or air handler. Return vents are usually larger than supply vents and are called grills. A filter is often installed either deep inside a return duct or right at the return grill to protect your HVAC unit from impurities.
How does air flow change direction?
As air moves from a supply plenum or main duct into a takeoff, it changes direction. Airflow has a hard time making turns at high rates of speed, just as we would driving off the interstate and onto the off-ramp. We want a gradual and smooth turn since we’re moving really fast. Air flow is the same. When there is a change in air direction in a duct, it takes roughly 24 inches for airflow to restore its pattern. Takeoffs should thus be 24 inches away from any turns, transitions, or the end cap.
Can an HVAC system be blocked by furniture?
Likewise, if the vents are blocked by furniture, your HVAC system will work harder to achieve the desired temperature. This wear and tear will shorten your HVAC system’s lifespan considerably.
What is a plenum?

When too many duct branches are connected, air flow is very bad.
