Room Air Conditioners…

I am needing to find out the cost of the compressor for the air conditioner of a 99 tahoe, from a chevy dealership not an aftermarket. I will also need the orphus?

i sleep like this everyday and i just want to know if it is the one causing my back pain, or maybe its my mattress sinking down could that be the cause for back pain?

The hole for the a/c is near the ceiling so the air blows right into the ceiling. Plus there was mold growing in the area where it blows out. I’m going to try a diverter but any other ideas.
