I am having an HVAC system installed in my basement. I would like to
know what is the consensus/general opinion regarding the use of Flex
vs. Metal ducts? Which should i use?

I have had 3 companyies tell me i should use metal as much as possible
and use flex where necessary. Another two tell me everyone is using
flex these days and there is no disadvantage.

Please advise.

thank you

metal passes air with less restiction so it can lead to long term $
savings.....

flexible saves bg bucks on install

since yours is a new install what system did you have previously?
