Bosch Cool 4000, Portable AC

Great unit, keeps room nice and cold, easy to use, wheels to help move from one room to another, packaging great, cut ties at the top, lift outside box off the unit very neat unit great relief from this heat. Tried to order another unit for my mum but unfortunately out of stock

The people saying it doesn't work have not sealed the room properly that's doors and the window must be air tightish the window kit works on vertical lifting old style sash windows that you lift up NOT OUT then the kit fits perfectly. Within minutes it was pumping out 11.3 c air while the room was 31c no doubt it can put out colder air once the rooms air that's feeding it drops, within an hour then room was 26 but the walls being solid in my house store heat so if you stood near them you could still feel the radiating from them so the air con is battling against that at the moment. Obviously Bosch won't make a lump of junk as some have claimed. Night time mode is also quiet enough to sleep with. Very happy with this purchase.

Yeah, very good! The noise level is reasonable for the job it has to do - at the end of the day it's never going to be quiet, it's an air conditioner, but it has definitely saved us and saved our sleep over this heatwave. Set it up properly, with the seals, turn it on, forget it, be patient and let it do it's job and you'll have a lovely cool room.

The remote control has got a problem in that it sometimes doesn’t want to work.

Bosch Cool 4000 Portable AC. The product seems good, and the noise level is acceptable. Unfortunately, I received the unit without the window panel adapters

Works very well. We have a large upstairs sitting room which has been unbearably hot, and we knew it is bigger than the specified room size. However this unit does effectively cool the area where we sit and the cool air falls over the gallery and cools the downstairs room as well. It runs very quietly and we are very pleased. It is, however very heavy, and was a struggle for two 80+ year olds to get upstairs.

You can see the photo below for a newly purchased portable air conditioner from Bosch with a gap.

WASTE OF MONEY. I am sending it back. Not even good for a room. The fitting for the window is not good for UK windows and the heat from outside coming inside. Very noisy even in sleep mode. For 600£ ,is NOT performing. Needs at least 12000 BTU .
