Chengdu Gree air blower is expensive to install. What's the difference compared with multi-line installation?

It is a little more expensive than ordinary air conditioners, about 1 10,000 to 20,000. I have installed an air duct machine at home. I looked for it for a long time and asked Nanhong to install it. It's been used for a year, and it's still very good, and the sound is very low. They pushed it online at that time, but it was much more expensive. I have a diaosi. Without money, I feel insecure. I suggest you install one. It's not bad to hear their introduction.
