My experience with Haier is utterly shi....t. When it first came, it had a leak in pipe leading to compressor and hence gas refilling was a regular feature for 3 seasons. Afterwards its heat and cool valve that switches mode on compressor decided that he had enough of giving me service and went berserk. since last two seasons it switches to heat mode in the middle of the night.
Now i have discarded this piece of junk and moved to Kenwood. Lets see how good or bad is this.
I have Gree in other room installed since last 7 years, working good and fine. This haier is or rather was with me for 6 years.
