I just got a little AC (8000 BTU). It works Ok, I guess its a bit small for the room (20m2) but even just bringing the temp down from 30C to 25C is enough of a difference to stop me from sweating.
I bought it second hand but it looks almost brand new, the previous owner used it for a few months and then had it in storage for 8 years. Question is though, how likely is it that some of the refrigerant has leaked over all those years? Would bringing it in for a refill likely make a difference?
I miss the winter and keep fantasizing of 16C.
