Generally speaking, it's good. I chose their Green Park HVAC because their company has been working for a long time, and then its scale is relatively large. It seems that there are six branches in Hubei, and then their after-sales service makes me very satisfied.

What I want to say is that you have to find an after-sales company for the decoration of heating, and no one will find another heating company no matter how much money. My friend's heating is broken because he installed it in a small heating company, but that company didn't. The heating is broken, so I'll find someone else to fix it, and no other company will go. Later, I put in a good word with the HVAC people in the Green Park, and they didn't fix it either.
