A dream solved HVAC problem

I have been overtly stymied by the HVAC distribution inside my house.

It doesn’t seem to matter what time of year it is but, the temperature inside the house is never consistent room to room.

I have tried to redirect the HVAC air flow by closing some vents and door to certain areas of the house. This had no positive affect at all. The HVAC unit is still in good operating order and has been routinely checked out by the local HVAC company. So, I was really stumped with what I should do. Of course, my first idea was to go online to find some sort of answer. That was a mistake because there was just too much information. And, I couldn’t tell legitimate information from a sales pitch. Finally, I just decided to let it go and quite worrying about it. Then, one night, I found myself in that state between sleep and consciousness. An old memory of my childhood sort of floated up to me at that point. I remembered being at an old cinder block motel on a lake when I was like 5. It was a beautiful location but a modest sort of lodging. The suite was fairly large with a separate bedroom and galley kitchen. There were these little fans installed in the walls that helped regulate the temperature by pulling or pushing the cold from room to room. This was it, I found some of these ventilators online and immediately ordered them. Well, the puzzle has been solved and our home now has consistent temperatures throughout.
