How to minimize noise in the duct run

There are a number of ways to minimize noise when it comes to ducting. There are several duct type options available to use when venting your range hood. In this article, we will explore the best practices and best duct to use for minimizing noise.

Best duct type for minimizing noise

For best performance and noise levels, use rigid ducting. This duct type will provide smooth airflow and should not move around when the range hood is turned on.

Which duct type to avoid if you have noise concerns

For the best and lowest noise performance, avoid flexible duct. Flex duct can move around a lot, especially with high velocity systems like range hoods. The extra movement will increase noise levels. Flex ducts also tend to have folds, which can increase static pressure and cause more turbulence.

Reduce 90 degree turns

For best noise, use maximum one 90 degree turn in the duct run. If there are multiple 90 degree turns, try using multiple 45 degree turns instead. If the turns are less sharp, it will help with noise levels.

Insulation around the duct

In some cases, using wrap insulation around the duct can help minimize noise. It also helps to ensure there is no condensation build up which changing temperatures in any areas that are not temperature controlled.

Consult with a local HVAC professional

If you require any further assistance or need more suggestions for noise reduction, it might be beneficial to consult with a local HVAC professional for further suggestions.
