Most portable air conditioners are capable of cooling small spaces that are not over 450 square feet. Many people enjoy using this type of cooling unit to cool small rooms or offices because the units are rather small and there is no need for a large central heating/cooling unit. The units are most easily portable because they roll on wheels and can be rolled from one room to another without much hassle.

Almost all of these available units have a window and ventilation kit that is included with the unit at no extra charge, and most units are very simple to operate. Windows on a portable cooling unit is required for ventilation, while trays on the unit are used to collect condensation. However, some units are accompanied with a built in water pump, which allows for self evaporation.
