What are the two types of registers in an HVAC system?

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

Answer: (A)

Air must move from the HVAC system into the living space and then back to the system to keep the air balanced and the temperature consistent. The two types of registers are supply registers and return registers. Supply registers are the openings that release conditioned air from the furnace or air handler into the room, distributing heated or cooled air to achieve the desired temperature. Return registers are the openings that pull air from the room back to the system so it can be reconditioned. This creates the essential air loop: supply air goes out to the space, and return air comes back to be recirculated. Other terms like intake and exhaust, outdoor and indoor, or primary and secondary don’t specifically describe the function of distributing air into the room or pulling air back into the system, so they aren’t the standard terms used for registers.
