Which salary is higher for installation and maintenance of central air conditioning? Which is better? What is the specific salary? I am in a hurry. A friend who knows can help me. Thank you.

The installation of commercial projects without technical content is also subject to design drawings. Unless you can understand some designs and have experience in the future, it will be different to take over the project yourself. As long as you understand the principle of air conditioning, you can explore it yourself slowly. At present, the after-sales service personnel of well-known manufacturers have high salaries. It is said that the monthly salary in Oaks, Zhejiang is 5,000 to 6,000, not to mention the extra money. After the warranty period, it's up to you. A set of tools and an apprentice is definitely a good way to repair central air conditioning, but there are few places to learn. There are many people who can repair household air conditioners, but relatively few people can repair various central air conditioners. You need to practice slowly and accumulate experience.
