The external unit of Hisense AS-07HR4SVNNT1 air conditioner is very noisy, when you open windows at home, it becomes unbearable. There were 2 failures with him, and both for the same reason. Literally a week after installation, the indoor unit flowed. I called the company, with grief in half I was replaced. They installed a new one, worked for another 2 months, and I turned it off, the summer is over. The next year I turned it on, and the new block also began to drip, and this time it is already much larger. Inside, everything is bent, in terrible condition. The air conditioner is of poor quality, moreover I will say that this is an extremely unsuccessful Chinese model, and indeed the company as a whole. Poorly done, of course, he coped with the task with his own, cooled well. But to buy such a system for 2 months, I think few who dare and want. I do not advise, it is better to dig and buy a really good and solid system.
Minuses
The quality is disgusting, not worth the money!
