Those portable Air Con units are very loud. I bought one to cool a guest room and the guests had to turn it off. They sell them everywhere, Bing Lee, Harvey Norman, etc etc.including Bunnings, but they are useless because of the noise and need to exhaust warm air through a window opening.
I had to laugh at the Hound Air Con unit, here:
