Read our review of the Whynter unit here. It is the best indoor portable air conditioner in our view.
This allows the heat from the room that you are cooling to be moved to the outside. There are some homeowners’ associations that forbid residents to use window units given that this equipment is designed to hang outside of the window.
Portable ac units are free of pieces that protrude from the outside portion of the window and violate these rules.
Given the fact that these units are mobile, you can move them to any room that needs to be cooled down. A window air conditioner unit, however, has to be installed and thus, it is contained to a single spot which is far different from portable ACs that can be moved to upstairs bedrooms or downstairs studies according to your preference.
Another major benefit of these models is having a number of flexible options for installation. You can move them from one window to the next as needed. Moreover, it is possible to install these through doors when you use portable AC install kits.
Finally, these can be vented through the ceiling with a kit for doing this. Ceiling vent kits are common when installing these products in server rooms.
