I bought an LG G09VHT air conditioner, as I trust this brand. LG has a lot of equipment at home and it doesn’t let you down, but now isn’t about that.
Air conditioning is quiet, but only at first speed. There is a useful auto-cleaning system, and it can also work on heating. The outdoor unit is made of metal. The indoor unit is not made very high quality, from cheap plastic.
I do not like the instruction, everything is planned, brief and not intelligible. In general, you read it and there are still many unresolved issues.
Energy efficiency is low, this model belongs to class C.
Only 2 LEDs are installed on the case, there is no indicator of the operating mode and temperature.
A noisy outdoor unit, buzzing, and strange - jerky, but behind the noise of cars they are almost inaudible.
That's how I became disappointed with LG, the air conditioning is of poor quality, I think this is their significant omission.
pros
can not only cool, but also heat, there is self-cleaning, an external metal block.
Minuses
the indoor unit is poorly made, few indicators, noise
