Diagnosing an aircon fault without regassing? - merlin
For the last couple of years I have regassed the aircon in my Mazda 626 only for the aircon to stop working after a few months presumably because there's a leak. This year I thought I would see if I can get the underlying issue fixed. Tonight I spoke to an aircon specialist who said that he would charge me £20 to tell me what's the cause of the leak. He said that he didn't need to charge the system to find the problem.

From speaking to garages in the past I thought it was difficult to identify aircon leaks. They talked about having to regas the system with some fluorescing dye to find the leak.

So is it possible to diagnose an aircon fault without charging the system or is this aircon specialist simply going to charge me £20 to tell me the condenser has gone, which I suspect is the most likely reason for the gas leaking anyway?

There are various ways of locating a leak on an a/c system,but probably the most popular is to charge the system with refridgerant and an ultra violet dye.This way the system can be brought up to pressure and hopefully the leak can be found with a u/v lamp.Another possible way is to charge system with OFN(oxygen free nitrogen)to see if the system will hold pressure,but this requires another piece of kit.Btw I would suspect that the condenser or the aluminlium pipe that runs in front of it are likely suspects.hth

Thanks - I think I will try someone else rather than believe this aircon "specialist" who says he can identify the leak without charging the system.

Does anyone know somewhere or someone who's reliable that fixes leaking aircon systems in the Aylesbury area?
