Thanks for the info. Your rough estimate is a big help.
I can't believe no one has a rough guess as to what the minimum return duct size needs to be on a 100,000 BTU furnace . . . or should I be posting under another heading?
I just got a new furnace installed and I am wondering if I have enough return air volume for my system. I have a 100,000 BTU Carrier 96% eff. furnace. What should my minimum return duct size be?...
