Choosing the right portable air conditioning unit for your basement will depend on various factors. A few key points of consideration are the square footage of your basement, the layout and design, and whether or not you would also like to use your unit during the winter months as a space heater.

Some air conditioner units are more geared toward technology and synchronization with other devices for convenient control. Others are more of a simple and easy to use old fashioned setup. Depending on your personal preference, certain units may be more or less appealing to you for this reason
