Which HVAC component is responsible for air circulation within the duct system?

• A. Compressor
• B. Blower
• C. Thermostat
• D. Expansion valve

Answer: (B)

The blower is the HVAC component that plays a critical role in air circulation within the duct system. It is responsible for moving the conditioned air produced by the heating or cooling system throughout the ductwork and into the living spaces. This circulation is essential for maintaining consistent temperatures and ensuring that air is delivered effectively to each room, thereby enhancing overall comfort levels within the building. The blower accomplishes this by drawing air into the system, where it is either heated or cooled before being expelled through the ducts. Its operation is controlled by the thermostat, which signals when to turn the blower on or off according to the desired indoor temperature. Understanding the blower’s function highlights its significance in the overall HVAC system, as it directly affects air distribution and efficiency.
