spacepak a/c system

I surveyed a job and I have to install a vertical mount high pressure air handler.I am using 8x8 ductboard approx. 3-4 ft. up to a tee and only able to branch 4-6 ft on one side and 8ft. on other. My supply tubing will have 10 on one branch and 8 on the other.I am conditioning 2 floors. My supply lines for upper floor will be 15ft long, even if to long and lower flr. will be ran out thur ceiling, down walls and into floor beams ,which will be exposed and into ceiling below.Those runouts could be about 25 - 30 ft.Now my question is will I have a balancing problem. Oh yeah, ceiling will sheetrocked and I won't have access to run baffles. Do you think this could be a problem for air balance.
I was always fasinated with solar. I am currently unemployed and I would like to start installations but I have to get certification. I live in central new jersey.Can anyone give me some direction?

    Balancing Act

    The flex take-off's should be close in lengths. I highly recommend contacting the nice folk's at SpacePak about this.

    Based on what you posted, you should be okay, but check here to be sure. You can download the installation manual for future reference.

    In all the years installing high velocity ac systems there pretty forgiving. Spacepak does offer a screen that clips in the take off to reduce the airflow. I am not sure if they come with kit anymore but I use them on small areas like bathrooms and they work great. There are 3 or 4 sizes.
