What provides the pressure difference needed to force air into the duct system and throughout the room?

Atmosphere
Drive clip
Blower
Canvas collars

The correct answer is: Blower

The correct answer is C. Blower. The blower is responsible for creating the pressure difference needed to force air into the duct system and throughout the room. The blower motor powers the fan that draws air into the system, pressurizes it, and then pushes it through the ductwork to distribute it evenly throughout the living space. This process is crucial for ensuring proper and efficient airflow in a residential HVAC system. Options A, B, and D are incorrect: A. Atmosphere: While the atmosphere does play a role in the overall air pressure in a system, it is not the component specifically responsible for creating the pressure difference needed for airflow within the duct system. B. Drive clip: Drive clips are typically used for securing components in HVAC systems and do not provide the pressure difference needed for air distribution. D. Canvas collars: Canvas collars are used in HVAC systems for connecting ductwork, but they do not generate the pressure difference needed for airflow throughout the room.
