Also, OP, I haven't given it a ton of thought, but you may need/want an exhaust fan to aid getting the hot air from the back of the air conditioner up the chimney. An alternative, at least for this summer, might be to put a window air conditioner in a basement window (if you can), and put the furnace blower on a timer to distribute the cooler basement air to the rest of the house (just have to remove the cold air return to allow basement air into the furnace's blower.)
Actually I never explained but that was my plan. There is a window right accross the furnace room and it's a slide window so I could install it properly in the window and just need to duct the cold air into the intake of the furnace. I'm guessing those AC units have their own intake so I could let it take the air from in the furnace room so it passes through it's coils then is fed through the furnace intake. Now only thing is I did not notice if the thermostat on that furnace enables to make just the blower run.
As for the condensation that could become an issue maybe though, or do the window units condensate outside?
This is how I imagine it would work:

I'd shut off all the vents except for the rooms I want to cool, if this does not work then I could just install the unit in my room.
