If you stood in front of it was the air actually cold, 9000 btu isn't very high so if its a big room or it catches the sun a lot its going to take longer to cool the room but the air its blowing out should be a lot colder unless its developed a fault.Got the 9000btu portable air conditioner out that we inherited. Bought a window seal kit from screwfix. Got it all setup and vented. Turned it on to max. Left it two hours. It's done sweet fa. Gonna sell it and go back to windows open and fan on.
Apparently the single hose ones are by the laws of physics rubbish. Dual hose ones that suck in fresh air from the window as well, are better. Looks like you could convert a single hose one with some cardboard/plastic tupperware/gaffer tape etc and an additional tumble dryer hose. I cba.
What unit did you end up getting?AC unit is here and cranking away, be interesting to see how low the temp goes.![]()

A school I was working at moved the ICT suite and they cheeped out on the air con for the new room and got a portable unit instead of the split type that was in the orginal room. Obviously it wasn't as good as the split units but it did well to take the edge off the heat considering there were 32 computers, a projector, 30+ children and an adult or two.
Edit:
I missed your post saying it was blowing cold air so it sounds like its not powerful enough for the size room although it would need to be be on longer than 2 hours to bring the temp down a lot. I've seen multiple social media posts about super markets emptying their freezers because its too hot for them to keep everything cold enough so you can only expect so much from a small portable unit.
My moms place is a corner property and has 3 big windows so cooks in weather like this, my sister has split air con, but I rent so can't poke big holes in the walls so made do with having the windows open when the temp dropped over night then closing them up again before it started to warm back up.

I keep putting it off every year but this house retains heat and the bedrooms are a sweaty 28-32c at night with the windows open![]()
Sounds like it was just too small for the job then, I've occasionally seen 12000 btu portable units advertised and just found out that you can get 18000btu portable units as well which I didnt know.It blows cold. With AC it got down to about 26.0. Still poor, but it is a loft conversion and on one side of it is the pitched roof which gets uber hot. When I turned it off and went back to fans and windows open, it went up to 30c within about ten minutes. So it was doing something to be fair.

Well it's not quiet, but not sure any are! It's all a bit subjective really.What's the noise like?
I'd love a proper split air set up, but not possible sadly. The current temp in my bedroom is priceless though (21c...)Gucci belt level air con.
Hottest I have ever experienced was about 45c in Nicosia Cyprus. It was disgusting.I can't even pretend to understand 50 degrees of heat![]()
My mate used to live in Rome and I would visit him. One of my visits there landed in a summer heatwave.Hottest I have ever experienced was about 45c in Nicosia Cyprus. It was disgusting.
Anyone have those Dreo stand fans with the 8 speed? Is it significantly better than those regular stand fans?
The “quiet” ones are often just swamp coolers which work well until you max out the room’s humidity and then you experience how the inside Satan’s codpiece must feel.Well it's not quiet, but not sure any are! It's all a bit subjective really.
