I kena compressor leak is after topping up gas, it will be cold for about a week then become hot air... Thats the symptom.

Technician suspected leakage either in compressor or the copper pipe. But luckily i told them to change the compressor first instead of hack out the pipe and replace...

Mine is Samsung inverter also about 5 years old.

You can always ask the technician if they will charge just to inspect.. some just charge transport fee only

For my case, they said I had to change both aircond unit and compressor. But of course u can ask the aircond guy if they can only replace the compressor.

Mine i changed the whole aircond, so they charged me RM280 for the installation fee and removal of the old unit
