We are planning to add grill on this duct for return . Or we can go for perforated duct ..
I like the perforated duct idea. Can you provide a percent open and area you'd need?
Free area req for 2nd floor return duct - 2.8 sq fts Free area req for 2nd floor return duct - 2.5 sq fts
can we remove the 'bend' in these return?
Something like this?...
