I own a 2007 Lancer for the past 3 years. The year I bought it, AC was not cooling appropriately at the start of the summer so I went to the AC guys he said that refrigerant is low, he fil it up and it starts to work. Fast forward to next year same time and AC is back to old routine, went to the same guy he said that your system has a leak (as refrigerant did not went missing in an year), he inspect it and told that compressor is faulty, so we replaced the compressor, fill it up and it starts to work.
Again fast forward to the next year (not at the start of the summer but 2-3 months into it and maybe because this time I did not drive the car that much due to Covid and WFH), AC lost its cooling in a span of a week, went to the same guy, he check the system and told me that high pressure line is leaking at the punching points. So we got the new pipe, fit it in, fill the system and it starts to work but this time only for a WEEK.
As today I went to F7, came back after an hour or so, the car was in shade, start her up and as soon as I turn the AC on I heard a blast (initially it felt like a tire blast) and I came to know that high pressure line is not leaking but RIPPED OPEN this time.
I would really appreciate your suggestions/ feedback/ experiences that can help me diagnose this issue and also looking forward for the recommendation of the AC guys who really KNOW their work.
