During inspections I use this tool to destroy the arrogance of some immigrant clown who installed 4 inch to bedrooms, nothing to a bathroom and had a 5 ton in attic with no filter or return, only sucking attic hot air, and he said this is how they do in Fl.

I can also see the value of showing this calculator to a homeowner if you are recommending they need larger ducts after your load calc.
