I use to have an upstairs neighbor who loved to play loud rap music indoors just like he does in his car. When it was time for him to jam out, I closed all my vents, then turned my gas heat up to 85.
Maybe 10 minutes later I would hear his ac unit turn on by my window and he would take a break and leave his unit.
I too open and close my vents up to 90%, just leave some air flow. I leave that adjustment year round as the smaller rooms seems to get warm or cool faster than the larger ones. By adjusting the opening it helps to balance this all out on a single level unit. Most 2 and 3 story homes should have a different "zone" for the different levels.
