Can I mount a window A/C into the wall, exhausting to the attic?

My room gets hotter than any other room in the house. I can't mount the air conditioner in the window because my room is in the front of the house (neighborhood rules). On the other side of my room is the attic above the garage. I wanted to mount a window A/C unit into the wall and have the back half hang in the attic.

The attic is pretty small (about 15x15) and has no attic fan. It has soffit and ridge vents. I realize I would probably need to install an attic fan and obviously have to run a drainage line for the water. My two concerns though:

1. Would this exhaust into the attic have moisture in it and be bad for the attic itself?

2: Having the back half of the A/C's coils exposed to the attic's 100+ degree air make the unit not work well? I live in New Jersey and it gets up to the high 90's in the summer.

Please let me know what I can do and I am very open to better ideas. Thanks

Yes, I have central air but it is a fairly large house that should probably have 2 units but I am looking for a cheaper alternative. If I installed an attic fan that was set to turn on at 95 degrees, wouldnt that be similar to the outside temperature? Im sure it wouldnt be as efficient but are you saying it would not work?

No it will not work! Two hot for the window AC you will kill the unit very quick.

YEah, you will kill the thing. Good idea, but it won't work.

How about a small mini split on that wall? Garage below? Small condensing unit outside next to the garage? That would work.

Then you could close the vents in your room and help the rest of the house.

Have you looked at the insulation between your room and this attic?

An AC is just a pump. It pumps heat. Using the pump anaolgy it would be like trying to use a 30psi pump to push water into a 100psi line.

Good one Ray. That hits the nail on the head nicely.
