A.C. gas leak

Hi all, quick question. I had my 2011 model re-gassed last week only to have the A.C. stop working again. The mechanic said he doesn't see a gas leak and the problem could be under the dash, which will be in the thousands to fix. Has anyone else experienced this before?

Thanks,

Sounds like he’s just guessing. They should have put some dye in when it was regassed. You need an ultra violet torch to check all over the system to see where the leak is. Take it to a specialist and not just a general mechanic.

Hi Steve, thanks for the reply. I've booked it in with an Auto Electrician who knows AC..... You were right about the guessing. They told me that it wasnt their thing, and referred me to someone else. We shall see!!

Most leaks are the condenser radiator - usually corrosion or stone damage. Let us know how you get on.

I disagree the most common leaks are along the shaft of the compressor, During winter and also a lot of the british summer there is no need for AC. This causes the shaft to stick in the seals of the compressor and when then called for use actually tear. thus causes small leaks. the way to get round this is every so often run the AC wether its required or not

I really cannot understand why people switch off aircon at all - it works equally well with the temperature setting set to heat as well as it does in cooling mode. It is better for the interior of the car and electronics to be in de-humidified air than wet air and the car doesn’t mist up inside on a wet day. Modern aircon systems don’t load up the car’s engine or increase fuel consumption to anywhere near the extent that the systems of the 1970’s and 1980’s did. Also if you read the owners manual it is recommended that if you don’t run the aircon all the time then it should be set to “lo” and run for 10 minutes every month so that the gas gets recompressed and the lubricant in the system gets spread around to all the moving bits otherwise seals dry out. It costs a lot less to run the system daily than it does to repair it when you find on a hot day that it isn’t working any longer.
