The ones I see at Home Depot (Maytag) vent hot air out the window via a flex
duct like a dryer. Unit comes with expandable panel to put in double hung
window with duct connection in the panel. The system recirculates room air
for cooling.

I was noticing on Amazon.com that the portable air conditioners (that
can
be
wheeled from room to room) have gone down in price. Consumer Reports
reviewed them years ago and said they weren't energy efficient. The new
units my Danby, Mobile Air and others are combo a/c, humidifiers, and
heaters.

Anyone have experience recently and are there any recommendations.
My apartment has the under window sleeve for air conditioners and I do
have
two, but one is as old as the hills and fails to work most of the time.
A replacement would involve getting someone in to install it, and
re-plaster
the wall around the sleeve. I could also use the portable heater in the
portable unit.

The only issue I have with the portable A/C's and coolers is they need to
be
set up in a certain method so that they work. If you set up this a/co in a
bedroom and you have cold air coming out of it. WHERE is the hot air
going?
Back into your house. Unless you have them vented your playing a squirrel
game and only helping the utility. Bite the bullet and get the through the
wall one fixed or replaced.

I used a portable for a job on the 4th of July in Phoenix. The unit was
out
side the room we were working on. I placed plastic over all the doors and
then ran the supply hoses into the room. The hoses were hung from the
light
fixtures blowing down on us. 40K btu held the room at 89 degrees, it was
115
outside. There was a steam header in the room as well.
