I'm having a home built and we've encountered several errors made by the builder which now leads to us question all the work for each subcontractor. Photos from the same floor plan show 2 a/c vents in the master bedroom and they are only installing one vent in my house. So my question is which would be the appropriate size duct for a bedroom that is 14x15 (210 sq feet)???
The other house I saw had 2 6" ducts in the room. The builder in mines is installing one 7" duct. The master bedroom faces the front of the house with 3 exterior walls and we want to be sure the a/c will properly cool that room and be efficient at the same time. Please help!
Also, what is the appropriate size duct for the other bedrooms sizes 11x12 (132 square feet)???
