Bosch Cool 2000, Portable AC

Th Bosch Cool 2000 Portable AC is brilliant! HERE'S WHY YOU SHOULDN'T GO FOR A CHEAP BRAND: I had previously bought a cheap one for sub £200. That was a waste of time as it sounded like a pneumatic drill and didn't give out anywhere near enough cold air for it - it struggled to cool the room down. HERE'S WHY YOU SHOULD CHOOSE A BOSCH: To cut through the confusing world of all the options out there, I just decided I would go for a reliable brand and spend considerably more money - Bosch was my choice and it has 100% been worth it. I only needed the smallest one as the room I want to cool down is quite small. It looks slick, it pumps out cold air in abundance. As air conditioners go it's quite quiet - I mean, obviously it does make some noise, but it's soothing white noise (a bit like the sound when you're on an aeroplane). If you want a reliably excellent portable air con unit and have the budget, my advice is look no further

Bought this just before the first heatwave in June ‘26 thinking Bosch was going to be a good robust machine. It definitely cools well providing ambient air is below 30° - beyond that it just really blows warm ish air around. The room I’m using it in is approx 9.6x 2.88 and had a vaulted ceiling in one half so it is a large space. (Instructions say it can only be used on air conditioning mode at 10°c below ambient temp max). It is EXTRAORDINARILY noisy. It buzzes very loudly intermittently which makes it very hard to sleep with whilst it’s running. Setting it up to vent through our timber outwards opening windows was a mission as well… had to buy a separate window kit. Final gripe is nowhere to store the vent tube when it’s not in use. It’s my first foray into AC in the UK - we’re having an extension built in the new year and we have decided to pay for a proper wall-mounted unit. However it is handy to have this and no doubt is helping keep a large space cool to work and sleep in though I shall be using it on timer mode and in conjunction with a fan to help keep me cool once it’s turned off and gone quiet enough to sleep!!

I have purchased a number of Bosch items over the years, and have always been able to register them for the extended warrantee. There has always been a registration card with the appliance, but this time no registration document. In this case no Bosch online registration system, I have found, recognised the unit. I have telephone all the Bosch call centres, I can find, and no one can register a Bosch Cool 2000 portable Air Contioning unit. I contacted the seller and all they could give me was German telephone number or Bosch web page with no address. This is good unit but Bosch lack of support is letting them down.

Well built , good quality, efficient cooling performance

Cools the room adequately and seems a quality build. Heavy to move around although it is on wheels. Noise level is quite high and I’ve hardly noticed a difference in sound level when on “silent”. The “sleep” mode isn’t much quieter either so I wouldn’t use it through the night as I’m a light sleeper and that would definitely keep me awake. Im disappointed with Bosch as they don’t sell the exhaust hose separately which is a bit silly if you damage the original hose or need to extend it. I’ve tried “off the shelf” hoses and the quality of them simply doesn’t match the quality of the Bosch hose. Very disappointing service from a reputable, trusted company.

Before buying my main concern was loudness. And even though it has “quiet” mode and also 3 speeds to choose from, it sometimes kicks in high and loud gear even when cooling is set on “quiet” or lowest speed. But… I cant really say it’s unbearable. We have mainly bought it to cool bedroom down for our 8m/o daughter, she seems to be ok with the noise, as we are too. On a hot and stuffy afternoon you just don't really mind it, a bit like white noise. Also had to buy longer hose (2m), as this one would not fit our needs (provided hose is ~1.5m), and had to 3d print suitable fitting for hose as provided one is only suitable for typical windows that lift up. Overall i give this device 4.5 stars. Would be five if remote controller buttons would be visible at night, now can only see screen but not buttons. And also those random high gear high speed moments..

It didn’t stand up well to the heatwave.

I bought this product after considering several options but ended up returning the product as it was impossible to register the product and activate the 2yr warranty...... read on. The Bosch Cool 2000 is a well known 'premium' brand name, quite expensive when considering the alternatives and said to come with a 2yr manufacturers warranty. After the delivery I tried to register the product, firstly on the internet - no joy; then by calling Bosch customer services - no joy. During the call to Bosch Customer Services (Home appliances),the agent said they were unable to register the product and passed me to Bosch Home and Garden. They said they were also unable to register the product but offered to pass me to Worcester Bosch (who do air con) and a very helpful lady there also tried to register the product. She couldn't either and offered to look into the matter properly and call me back. After about an hour, true to her word, she called and explained that the product is meant for the German market and was not meant to be sold in the UK. Despite her best efforts and after she took advice from Bosch Technical and Marketing, she informed me that there was no way for her to register the air con unit for me and consequently their was no warranty. Inevitably and having spent £500 on the unit, it wasn't acceptable to me to have no warranty and so it was returned through Amazon for refund. I've since bought a different brand name air con from a high street shop with a full 2yr warranty.
