With the new closets we had to extend the ductwork to the new wall so we weren’t just air conditioning the closet!
Here is the old register hole which I had to make a little bigger.
We used flexible duct for its ease to run and it’s acoustic properties. It helps attenuate fan and air movement noise that travels down the duct.
We also used this opportunity to replace the hard section of duct to our bedroom with flex to reduce the HVAC noise.
It definitely made a huge difference, muffling a lot of the noise we used to hear…
