Which component helps to reduce noise levels in HVAC systems?

Isolators are specifically designed to minimize the transmission of vibrations and noise within HVAC systems. By decoupling equipment from the structure of the building or ductwork, isolators absorb and dampen vibrations generated by HVAC components like fans and compressors. This reduction in vibration not only helps to decrease noise levels but also protects the integrity of the system, enhancing durability and reliability.

In contrast, while flex connections and turning vanes have their own important functions—flex connections help to absorb movement and reduce stress on ductwork, and turning vanes improve airflow efficiency and reduce turbulence—neither is primarily focused on noise reduction. Access doors are meant for maintenance and servicing equipment but do not contribute to noise control. Thus, isolators are the most effective component in reducing noise levels in HVAC systems.
