There's Nothing There?!?!?!

For the past few weeks we have been in contact with the builder and trying to get a hold of the crappy HVAC company that put in our venting system. The problem? The register or vent in the office (South/West facing corner room with two windows) has absolutely no airflow coming out of it and the vent in our master has a tiny trickle.
Well, after several weeks of waiting, scheduling a duct cleaning company to come out, and 30 minutes of arguing with the HVAC company just to get an appointment for them to come out and look at the problem....they finally came out and found the problem. Due in part to cutting holes in the ceiling of the garage and pouring over the pictures I took of the house in the framing stage (i didn't have as many angles as I would have liked). The two problems. The ducting in the garage that leads to the master is restricted to about 1" of flow space in the crappy flex ducting they put to bend around a beam that should not have been done, because they could have gone straight up. Then the kicker. There is ducting from the office to the wall and down the wall of the living room to the garage....and then nothing. Nada, Zip, Zilch. There is a 15 ft gap between the end of the duct feed to the smaller ducting going up the wall. Absolutly nothing there. Might explain some things. They are suppose to come out tomorrow to fix it, so hopefully we will finally have A/C in the two hottest rooms of the house by the time it gets to 90 Deg tomorrow like the forecast says.
No update on the driveway...plans are still in for review with the city.
