Duct and Plenum – Mini Split
6 months since my last question, we are now finally to HVAC. I had a company run a manual J for us and we are going with an 18k BTU ducted Mini – The Fujitsu 18RLFCD. Yes I know the total CFM here is a little higher than the unit runs at.
We are planning rigid round ducts. Am I ok to build the plenums out of Ductboard? the learning curve and availability of sheetmetal seems a little high.
Also, this is what I was thinking for the plenum and Duct sizing.
While the closet does share two exterior walls, I am not convinced we need to pump that much air into it, but will for now. Also, not sure we need the second return in the master, but might be nice so we can keep the door closed at night.
Texas – metal building, extreme insulation and very tight, with an ERV.
