The main factory in China that makes those 'scroll compressors' had a celebration not long ago for their millionth production. This is a mature industry - kind of really doesn't matter if it comes from China or Singapore, Vietnam, Korea, or Japan. I would not be a bit surprised if the Japanese brands were buying the china compressors.
Mini-splits are used extensively throughout the world, especially third-world countries where they can slap one of those in a brick building and go. Many of those places just don't have formal tradesmen. They are WAY more popular elsewhere than they are here in the US.
If you're going to DIY just make sure you address the warranty coverage. 99% of them will NOT cover a DIY install - it HAS to be installed by a licensed professional. READ the fine print in the warranty certificate. They CAN and do go bad, quit working. It pays to have 'a guy' you can call that will step in and help you out if you need it. I have one, he's so cheap the last time I told him he doesn't charge enough. LOL How often does THAT happen????
