Air Conditioner Pre wired or not

Thanks everyone for your ideas and thoughts on this. While I would like a second unit in the bedroom I don't feel the added expense of getting it wired for the unit would justify my purchase. I will instead save the funds and upgrade the ducted unit when the time comes. It has worked well and kept the unit cool but we would have liked to have just a bit better cooling capacity plus the comfort of a second unit if one happened to fail unexpectedly.
