Has anyone seen any split portable ones for sale locally? They were common as in China, you have 2 boxes with a detachable refridgerant/power hose assembly between them, so you could run it thru a vent and reconnect it and then have a closer to real airconditioner system.

 

My current portable is noisy as since the compressor is inside, and it exhausts hot air so outside air comes in to replace that bringing pollen and other stinky stuff with it. Not going to be able to afford to do the reclad on that end of the house for a few years so dont want to pay for a proper one to be installed just yet.
