What is the installation prospect of dry central air conditioning? What is the salary?

It depends on the technology. If you have good skills, you can work as a mechanic in a big company in the early stage, with a salary of about 300 a day, but it is much easier than the construction site. Later, with contacts, I can bring workers, start companies and contract projects myself. This is the most profitable, and it is estimated that it will be conservative and pure for one year. Of course, the most important thing is good technology.
