Which are the two types of registers commonly used in HVAC distribution?

• A. Supply and Returns
• B. Return and Intake
• C. Outdoor and Indoor
• D. Primary and Secondary

Answer: (A)

In HVAC distribution, air moves through two main kinds of registers: supply registers and return registers. Supply registers allow conditioned air to enter the room from the air handler or furnace, often with diffusers or diffusers/grilles to spread and control the flow. Return registers act as the air intakes, pulling air from the room back to the system to be conditioned again. This creates the necessary loop: air leaves the space as supply, then returns to the system as return. The other options aren’t right because they don’t describe the two standard register types: intake isn’t the typical term for a register, and outdoor/indoor or primary/secondary refer to locations or piping rather than the distribution outlets.
