My aircon has not been working for a few years now, the last time i got it done it leaked within 2 weeks and then nothing, so got the guy back to do it again (he done it for free) but again gone within a week, problem is, i know they put a dye in the gas, but i could not see anywhere on the pipe where the dye was coming out from, question is
1 are all the aircon pipes visible.
the pipes, are they in 1 piece
2 will i need any special tools or seals to replace the pipes.
