You may not want to get the portable inside unit.
A couple summers ago, we bought two of them - thinking that would be the ticket! No more window installations!!
Long story short - we did not like them at all. They are noisy and the motor throws-off a lot of heat INSIDE your house. Not to mention the continual dumping of the moisture collection drawer - the units stop running... or switch to dehumidify mode when full of water.
We even set the units up high and had them drip into a bucket... we were literally pulling at least a 5 gallon bucket full of water out of the air EVERYDAY.
We used them one summer and gave them to our daughter and her husband.
