3rd_Floor_AgainWe shamelessly bought a portable one here in Switzerland, De'Longhi Pinguino, pretty good.
CraigIsAwakeMy De'Longhi was still going fine when I put it out for hard rubbish after about 20 years.
Diligent-Apricot-416I love Black & Decker. Used to love Pingüino when Costco sold them.
dry-brushedWe used a portable refrigerative air con temporarily (with removable window kit & tubing), which did the job for the master bedroom when we had a newborn (waiting on the ducted installer).
Pretty sure ours was a Delonghi, but this was many years ago - so there could be better options out there today
FN-BoredDe’longhi penguino portable A/C units. Are really good $300-$500. But must be careful. Have to have a pan under them, at some point it will leak.
