What is the Difference between a Portable AC Unit and a Window Unit?
ALL AC units produce heat while cooling and part of the problem with portable units is that the heat can never be as efficiently ducted out of your room like a window mount unit can. Portable units have an exhaust hose out the back and gets extremely warm when the unit is running. Some of this heat will be added back into the room. This is why we de-rate the area coverage to a more realistic number. Another factor is if the room intended for the AC unit is in direct sun light or has items in the room that produce heat such as Computer Servers, etc.. Also, Portable AC Units are NOT intended for areas such as Kitchens!
