DIY Frequently Asked Questions / Portable Air Conditioner')">
Used to cool a small space, usually 400 to 450 square feet.
Mounted on wheels for easy movement from room to room.
Contains both the hot and cold side of the air conditioner in one unit. Is not permanently installed, but must be connected to some place like a window where the hot air can be vented. Most models contain window-venting kits that are easy to install and easily moved from one window to another.
May be either single or dual vent. Dual vent models circulate clean air back into the room and generally cool more quickly than single vent models.
Drip models have a tray that will need to be emptied every 24-48 hours. No-drip models may cost more but do not produce any excess moisture.
