HVAC Closet for Return Plenum
Ducted mini-split on a 2100 sf one level, zone 3 good enough house.
Has supply plenum above it with duct distribution above that.
After hallway return air passed through grill is it ok to have a separation between the wall grill and entrance to the filter box? In other words, the closet space acts like a return plenum feeding the filter box not attached to the wall grill.
