Its going quite well, really. REmembering its a personal cooler, not a room cooler, of course. I did try it in the study, and also the loungeroom but it was not enough, because when you stand up to do something like make dinner, its horrible hot outside the cool zone which is very small.
For my bedroom, its been excellent. My bedroom is the hottest room in the house, and during those 44-45º days, I was able to nap very comfortably. I tend to leave it on because it cools my sheets when I am not sleeping… And today I left it on with my shorts and tshirt on the bed in front of it, whilst i went out shopping. Cool clothes when I got home and out of the street clothes.
So for me, its a positive result for my bedroom (and the noise ranges only from around 50Db to 70Db, and although I am a light sleeper, those levels dont bother me. Its white noise. I’ve yet to get an electric bill for the current quarter, but I wont know what the PC9 is chewing up because I also run an old TECO skinny window unit in the loungeroom and it eats electricity. But I’d rather put up with a big bill than be hot.
