Which items are considered the main air-side components of a HVAC system?

• A. Evaporator, condenser, compressor and metering device
• B. Duct sections, vents, and diffusers
• C. Motors, bearings, and belts
• D. Filters, humidifiers, and thermostats

Answer: (A)

The main air-side components are the parts that handle the movement and delivery of conditioned air through the building. Duct sections, vents, and diffusers form the actual air distribution path, carrying air from the air handler to rooms and back. The other items are part of the refrigerant loop or system controls: the evaporator, condenser, compressor, and metering device handle heat exchange with refrigerant and are considered refrigerant-side components; motors, bearings, and belts are drive components for equipment; filters, humidifiers, and thermostats influence air quality and control but aren’t the primary air-path components. So the items that make up the main air-side components are duct sections, vents, and diffusers.
