Ducted minisplit sealing
Hello GBA Community.
My passive house architect specified a ducted mini-split system, and figuring out where to house the indoor unit raised the question of how to seal it- it’s mounted tight to a surface, so I’m not sure what to do with the long edge that’s pretty much inaccessible. Also, I understand that mastic is the optimal way to seal duct seams, but what is the best way to seal the connection between the supply and return plenums (plena?) and the evaporator? Lastly, it seems that the three pieces will fit together like a puzzle, and that the evaporator won’t be easily removable for service when it’s all done.
Attached is an illustration of the design for reference.
Thanks in advance for any thoughts!
And big thanks for all the advice I’ve benefited from in the past, too.
