    Some air flow designer sent me a plan for a package unit.

    He has [2] 10" flex coming out of the plenum... One run is 50'+ and he has [6] 6" outlets on it.

    Second run he converts to 8" after 10' of 10", runs 40', and takes off [2] 6" vents

    Its a 2 ton 50,000btu rig. Is that sensible?

    I don't know about the ducting, but isn't 2 Tons = 24,000 BTU? was last time I looked. Or is that 2ton AC and 50K heat? Just curious
