The AC unit must be vented, there are other options such as venting
out different style windows, into drop ceilings and of course using a
dryer vent. I have included some corroborating links about venting,
mostly about dryer vents, and some including other options.
Can I vent a portable air conditioner out a dryer vent?
Generally, this is not recommended by the manufacturer, especially if
the diameter of the vent hose is greater than the diameter of the
dryer vent. A standard dryer vent is 4". Most portable air
conditioners have 5" exhaust hoses. Some units have smaller diameter
vent hoses (the Delonghi units, for example) and these units may be
vented out a dryer vent. However, you should not use the external part
of the dryer vent that has flaps, as the compressor is not strong
enough to push these flaps open. If you need to cover that exterior
opening of the vent, we recommend using a screen.
Could you explain why and how portable AC's are vented?
Portable air conditioners extract hot air that must be vented. If the
hot air is not vented, the portable air conditioner will not be able
to cool a room effectively. Window and venting kits are always
included with our portable air conditioners at no extra cost. You may
also vent the portable AC through a wall vent, into the attic or drop
ceiling, or even around a door! You are only limited by your
creativity. *** For venting these Portable AC systems through
casement windows (windows that crank out), Plexiglas can be used.
Simply cut the Plexiglas to the size of the window, cut out a 5" hole
to vent the hose, and place this over the open window. not only is
the Portable AC vented, but Plexiglas will allow the same amount of
light to pass through the window as before.
Can the exhaust hose be extended?
All the Portable AC's come with the standard hose length of 5-7 feet.
If you need a longer hose, they are readily available at the local
hardware store but it is a good idea to avoid hose lengths over 12
feet as well as 90 degree bends. You can also vent through the dryer
hose as long as the hose diameter is 5" or more and the outdoor
venting flap is removed.
All of the portable air conditioners have to be air
vented and have a 4-5 foot vent hose. They can be
vented to a sliding door, a window, a hole in the
wall, or through the dryer vent.
