Hope I'm in the right place...

Summer is here, which is bad news for me due to excessive allergies. I
literally cannot sleep with a window open or even use a window AC, as
even with the vent closed, it'll still manage to draw in a little
outside air....the pollens give me nocturnal asthma and I have so much
trouble breathing I can't even fall asleep. I lived in a home with
central AC last summer, but this is no longer the case.

Basically, I need a portable AC unit to cool a 13x20 bedroom that will
vent hot air either under a doorjamb or - I'm wondering if this is
even possible - down a heating vent. I see a ton of models on eBay and
locally and have no idea what to look for. I don't mind emptying a
water reservoir, but I simply cannot have the windows open, period. If
I can solve this problem for around $500, all the better. Any advice
is MUCH appreciated. Thank you.
you got to get rid of the heat from the A/C unit someplace.. the plastic
6 in. hoses attached to the unit should easily be place in an partially
opened window(with a wooden piece the size of the 6 in. hose and then
the window closed..the hot air will travel out the hose, so you not
gonna get any outside air into the house........ the portable units are
kinda expensive, but keep looking. we used them in a very large office
building when the cent air went out and the hot a/c air was vented out
the air intakes that were not being used at that time due to the cent.
a/c being busted...
