After 2 years of use, I can say the following disadvantage.

1. The outdoor unit drips liquids during hot use in winter (the technician said it is a manufacturing issue because something inside is placed close to the metal sheet, causing a temperature difference when it heats up). I should note that the same problem occurs with the second corresponding air conditioner but in a 12 model.

2. In the summer, sometimes it lives its life, meaning that where it blows cold air, it suddenly starts blowing room temperature air. It has done this 5 times during the summer.

3. And I don't know if it's an installation error, it drips water or the indoor unit in the cold.

4. The plastics creak in the indoor unit when it is in heating mode

The indoor unit has some quality, but the outdoor one is terrible; it makes noise and has quite a bit of vibration. Worse than a supermarket machine. Not to mention it looks just like some Chinese one for half the money. Just the remote control alone shows where it comes from.....from the depths of Asia with a BOSCH sticker

I do not recommend it. If you happen to have a faulty product, the service does not help even within the warranty period. Ours started to accumulate ice in the internal unit and make a lot of noise that woke us up every night before it even turned a year old. The service came with nerves and rudeness and after imposing a reinstallation in another location (which did not solve the problem), they started blaming the (few) pet hairs in our house (we have 4 air conditioners from other companies that have never had a problem). The company itself does not return calls to fix the issue. The result is that the machine will end up in the trash. Choose another company.
