I wish Carrier would make free-standing portable room air-con units that have a heat pump (working similarly to motel room units). I have to buy a foreign unit to get that. I would sure buy a Carrier.
I don’t know if they make a true portable system, but they do make ductless mini-split systems, which are room or zone systems that are very economical to operate:
