Although it is almost a year later, I have to admit that Air Supply has in fact made a serious effort to fulfill the promises made when we paid for the system. The house now has all but one of the rooms finally getting great airflow. The suggestion was made to either install another and bigger vent in my office where it's a cookhouse in my home, or install an air conditioning unit in my window of the office. I prefer the latter but will see of Air Supply finally gets this last and most important problem resolved. I'll publish a final rating and review when and if everything is resolved.
UPDATE
I must say that the folks at Air Supply took responsibility for my prior dissatisfaction and bent over backwards to correct things. They finally got things near perfect. We need to remember that every home has its own unique challenges and mine provided plenty for them to tackle. I must admit they did an outstanding job on working to make sure my expectations were met!
