A/C Gas Leak
I haven't used my car for a long time, about six months. During this time, the batteries were disconnected. When I prepared my vehicle to use it again today, I realized that the air conditioner was not working. When I went to the service center, I learned that the air conditioner gas had dropped to 300 grams and the normal value was 920 grams. A leak test was performed and the missing gas was completed. There was no leakage in the air conditioning installation. If it is not used for a long time, will the air conditioner gas be missing in the vehicle or will there be a similar problem? I wonder if it is normal.

Probably has a leak regardless of what they said. It's possible a seal that can barely hold when bathed in oil, can't hold as well without a fresh oil bath now and then. Then when bathed in oil again it passes the leak test. If the car is an '03, per your sig, a leak would not surprise me at all. So I wouldn't worry about it unless it leaks out too quickly, but it may also be good to go for many more years.

the bottom line is your car needs a little recharge... you may want to take the opportunity to get your A/C pressure sensor replaced now if circuit will get vacuumed to weigh gas refill precisely.
The compressor usually loses pressure slowly and the two A/C port valves are frequent offenders for more rapid leaks.
A/C specialists shops can get a bit heavy handed searching for leaks with parts canon instead of UV-Dies or gas sensor...
