I went to the car air conditioner, the master asked the brand, I called the answer shocked. We don't do that, I didn't even ask the reason. To the question of what difference does it make which brand of car, the answer is big. In my opinion, he has identified himself as a diamond-free master.
I do not recommend a clerk. A professional takes on any job.
I went to another master, they repaired it without a problem in about forty minutes, replaced a couple of rubber rings, refueled everything works without a problem.
