I know from personal experience that Gree's quality is poor and its service is even worse. I will not buy Gree products in the future anyway.
I have used two Gree products, a floor fan, the outer cover is actually fixed with a one millimeter screw nut, it is very inconvenient to disassemble and easy to lose. All other products have a fixed and convenient way of fixing, but it doesn't, it has to be brain-dead "unique".
A Gree air conditioner, the outdoor unit actually has a tail on the outside of the unit - a sensor attached to a normal flexible wire. Mine was installed on the sixth floor less than six months before mice chewed it off and it wouldn't turn on.
What's annoying is to report the repair, the repairman as soon as he answered the phone, told me that it was a mouse biting off the sensor wire (the repairman could actually guess accurately that it was a mouse biting off the wire, which shows that the failure rate is too high to be said), and asked me to pay for the repair of the 200 yuan out of my own pocket. The next day complained to the local city Gree branch (one of the largest cities in the country), replied that my natural environment is not good caused by the failure, indeed to charge. I really do not know the "environment" in the first floor, second floor bought Gree air conditioning that how to do.
Afterwards, I also put things through the official website of Gree to Gree head office report, hoping to get the head office's opinion. However, there was no feedback from the after-sales service of the head office.
Ran I used a brand of air conditioning, five years after the outside fan is broken, a call, immediately come to the maintenance, free replacement, no more words.
