Urgently ask Beijing property for the certificate requirements of refrigeration and air conditioning workers!

Where can I get an air conditioning permit and a refrigeration permit in Beijing?

Ask in public here and no one will answer you.

What is the operation certificate for central air conditioning?

Both are ok, but the certificate of pure air conditioning is more specific and professional. Refrigeration includes not only air conditioners, but also the operation and use of refrigeration equipment such as refrigerators and cold storage, with a wider scope. The qualification certificate does not need to be audited every year, and the operation certificate is audited twice a year.

Which is better to find a job in Beijing, boiler certificate or air conditioning certificate?

Spontaneous combustion boilers have been banned in the center of Beijing, and boiler coal workers have no job opportunities. Air conditioning maintenance mainly depends on your technical level and working ability, and has little to do with whether there is a card. I suggest that you start with the study of practical application technology, make good preparations for employment, and don't try to go past the idea of monopolizing the certificate industry. Now more and more attention is paid to ability, and more and more contempt is paid to certificates.

The main job is to turn the air conditioner on and off, deal with the problems in operation, and other things that should be done.
