Hi hi bro jaydee123....juz to share share my previous experience with my air con.....
previously me facing the same problem wiht my air con...tot not enough gas then i go top up gas at air con shop. ok for abt 1 to 2 weeks then not cold again....went to a few air con shop and all say some thing wrong with my compressor, need to replace.....re-con de cost abt 400-500 rm...:sad_smile:
i didnt change cost tooo expensive...then later my friend intro me to an acc shop...the boss checked my compressor and told me the same thing also, might have to change compressor becoz he supsect it i leaking....then later he suggested that dun change the compressor 1st, he will try 'servicing' the compressor by adding oil into the compressor and ask me to monitor the situation, if air con can run cold for more then 3 months then it is a very minor leak.....
after 'servicing' the compressor, he told me that my thermostat(the 1 inside the car, adjusting coldness de) needs to be replace also.
after those repair, my air con is running perfectly till now(almost half yr le), no problems at all...day time drive not hot at all (except for the sunlight coming in from windscreen and windows coz never put window film..)....and some times drive at night, air con so cold, even the fan on to low and the thermostat almost to 'off' position...:regular_smile:
and the best part is, all the repair cost is less then 100rm !!
Maybe you can try asking the air con shop to 'service' your compressor 1st before doing any major repair...
juz my 2cents.....
