So, I recently became a homeowner and my house has a serious air flow problem. It's probably partly skill issue but need help on figuring it out.

  
Here's the deal - I have an AC system with ventwork through a crawlspace. My house is a living room with a hallway and the hallway connects 3 rooms and 2 bathrooms.

I made an image with the layout, sorry i didn't include dimensions.

  
Here's the problem - When the doors are closed in either br1 mbr or br2 they just get insanely hot. Like it cooks. The problem is i can't leave them open all the time due to pets. when im sleeping my cat will just jump on my face all nightt and it's really fucking annoying. during the day i like to keep my office closed to keep them from distracting me from when im working.

  
but if i close those doors, there is literally zero air flow and i start baking.

  
is there a good solution here? do i need to install vents in the doors? feeling kind of at a loss. would putting holes in the doors solve all my problems?

  
I really don't want to put window ac units in every window - in fact i have one in br1 and it's the worst (midea u unit, dont ever get this crap).

what sort of solutions can i have to increase air flow with closed doors?
