When these units are on display at a retail store, the air conditioner rarely has a hose attached. In order for these models to work property, the heat from the interior of the room must vent to the outside.
Window air conditioner units and central air systems utilize Freon to transfer heat to coils installed in an outdoor unit. The fan disperses air to the coils to keep them cool.
Portable A/C units have a coil inside but there is still a need to keep it cool. Coils transfer heat but need a way to transport the heated air to the exterior of the building. The pictures shown here depict actual air conditioners with the proper set up.
These portable ac units have a minimum of one hose that disperses hot air outside. The longer the hose, the more power the unit uses to push the air through it.
Any portable air cooler requires installation of a venting kit, similar to a standard window unit. Venting kits for portable units are smaller than those kits intended for use with window models.
Some users will still encounter the same problems with installation as they would with window A/Cs. Study the pictures here carefully. Imagine how the unit will look after it is installed in the home before making a purchase.
Some consumers rightfully question the claim of portability once the unit is installed. Moving a portable A/C to different locations requires installing multiple venting kits or moving the existing kit along with the unit.
In some cases, the small wheels on the cabinet will not roll smoothly on carpet. Before purchasing this type of unit, it is important to decide if it is practical. In most cases, moving a portable unit is just as cumbersome as moving a window air conditioner.
