Return Ducts
December 13, 2021
I’ve now gotten the return ducts mostly in place.

First I had to open wall for the return vents.

Next, I constructed a box out of duct board for the ERV and dehumidifier returns.

It just barely fit, still allowing the ERV to be opened up for servicing.

I then made a similar box for the air handler return.

This one will use a round rigid duct to connect to the return plenum.

This required ordering more duct parts.

The final result is an intentionally indirect path to the air handler, designed to reduce sound transfer.
