Maybe I am too hard on him, but would not a pro be required to measure the airflow and say if it is adequate when installing a new furnace?
I recently worked with a hvac design school, but they looked at the system and just gave a promise to work on it once they install a heat pump in the attic to cover the top floor. No assurance that they would be able to get adequate air flow to the other side, although with this much duplication and expense it seems likely they could. But why not try to get the existing system to work first at relatively low cost. If it tryly can not, then spend the money for a whole new system.
I have met very few pros who actually measure air flow. Probably about 1 in 20 do it, whether with a flow hood, annemometer or by static pressure in conjunction with manufacturers charts. Most just feel the register flow with their hands or do nothing at all. It is a sad state of affairs.
Remember, Air Conditioning begins with AIR.
