Thanks for the comment. All of the registers have dampers. So if I get excessive air out the end cap I can throttle the damper. It’s going to be a trial and error process to get the air to the right places. The best arrangement woul have been to run the duct down the center with outlets on oth sides. For a number of reasons I did not do that. One of my big concerns was to avoid air short circuiting back to the return side without doing any cooling. I saw a setup in a shop not too long ago that had that issue.Last edited by kmitchl; 03-16-2019, 10:05 PM.

the ac and after about 30 minutes heard a drip. Water was coming out the bottom of the air handler. I opened it up and everything looked ok inside. All the drains were open. After thinking about it for a while I realized the blower was running so much air that it was carrying the water droplets from the evap coil right past the drip pan. Set the blower speed down a few notches and life is good.

No damage. Was a bit of revelation to figure out why it was dripping. After doing this installation I have a lot of respect for the HVAC guys. I had to do a lot of studying and watch a bunch of videos to get this sorted out. And this was just a single stage residential unit with electric strip heat. My house ac is two stage with three zones. If it ever has an issue I'l be calling the guy who did the installation.
