What is one purpose of a flexible duct connector in a duct system?

Reduce energy consumption
Improve air quality
Enhance airflow velocity
Reduce the transmission of noise and vibration

The correct answer is: Reduce the transmission of noise and vibration

A flexible duct connector in a duct system is used to reduce the transmission of noise and vibration. When the HVAC system operates, it can generate vibrations that travel through the ductwork, causing noise that can be disruptive. The flexible duct connector helps absorb these vibrations and prevent them from traveling through the duct system, reducing noise levels within the home. This helps maintain a peaceful indoor environment and prevents disturbance from the HVAC system operation.
