Portable Air Conditioner Venting Into Attic

If the room you re attempting to cool has an exterior wall that leads directly outdoors you can cut a hole in that wall just large enough to provide adequate venting for all the hot air you re sucking out of the interior space.

Portable air conditioner venting into attic.

Venting your portable air conditioner is easy. Fit the window kit to the length of your window and secure the kit in place. Simply attach any hose connector adapters and insert the hose. Hooking this up to your typical attic would be bad.

The condenser in your air conditioner works hard to get rid of heat and pressurize refrigerant for the return trip through your house. Put it in an attic full of blown insulation and you re forcing. If the ac unit is not vented outside or into another room the hot air will remain locked up inside the space. That unit has an auto evaporation function which is marketing speak for dumping the moisture that condenses on the evaporator into the vented air stream.

This will not only prevent the room from cooling but will actually make it hotter. According to the twh principle you can vent a portable air conditioner into any well ventilated space apart from the space being conditioned. The first option is to vent the portable air conditioner through an exterior wall.
