Where are the air-conditioning installers in appliance stores? What are those people doing everywhere?

Installation personnel are generally recruited casually, and they can be employed after training for one week. As long as you are smart and willing to learn, you will learn it in three to five days. The technical content of air conditioning installation is not very high, but it is risky when installing. Many installation supervisors need to be outdoor spiders. People who are afraid of heights can't do it. They should be flexible, and most of them don't want to do aerial work, so not many people do this.
