i took it to a aircon specialist it has never leaked and there are no leaks i have not used the aircon for about 6 months car has been off the road for ages and now back on i was told by the head technician there today (booked in for friday) that the seals dry out because the system has not been used so the gas escape.... when the system is working correctly the seals are fine because the refrigerant has a lube in it that keeps the seals,seale.... i have had a problem in the past with our spider when we went to collect it when first bought her there was pink fluid on the floor (please explain)
before i had my sportwagon re gased last year i had never had it done in the 7 years i have owned him but the air con was getting progressively warmer so thats why i took him in
please explain why these places exist if you never loose the gas unless you have a leak and the systems seems pretty reliable
i was told by alfa romeo that the system is never full from the factory so who is right
oh and by the way do you leave your air con on all the time or not if your the expert!!!!
If there is no gas in your A/C then HOW CAN YOU NOT HAVE A LEAK?
I have 15 years experience, NVQ level 1,2+3 in refrigeration and air conditioning and am F-gas certified, so do I qualify as an expert?
The more you use an air-con system on a car the less likely the compressor seals are likely to dry out. You state that the A/C hasn't been used for six months.
To answer your original question 'the compressor does not click when you press the button to start the air con' the compressor will not run if either pressure switches are open circuit. So more than likely, with the evidence you have provided also stating the fact that the car was recharged last year I would be quite confident that the charge has been lost again, hence my reply.
You have already stated that your expert has told you that the gas LEAKS out via the seals, why are you questioning what I have told you?
It is a know fact that most refrigerant losses on a car are due to the compressor seals, they do sometimes LEAK. But they should as a rule be gas tight, used or not.
Car air-con should be run at least once a week to prevent this happening (read your handbook)
I have owned many cars equipped with A/C for a number of years and worked on many more and have never had to annually top-up the gas. It isn't right and only necessary if YOU HAVE A LEAK.
If you are unfortunate enough to have porous compressor seals, then renew the compressor or run it regularly. A seven year old compressor will be a bit worn right? A stone may also have penetrated your condenser coil (like my BM which had a holed condenser, I renewed it, recharged it and the same gas is still in it four years later).
The only pink fluid you will find in a cars engine bay will be power steering/auto transmission fluid. UV dye will not be added by a manufacturer (they often don't approve of it) anyway it will be green. You cannot see gas.
And to answer your question; yes I do run my A/C all year round in my cars.
Fridges are hermetically sealed and car compressors are open, both need to be gas tight regardless of installation, if they are then the gas will last a lifetime.
All I've being trying to explain is that if you are having to pay to restore cooling in your car then something ain't right.
Anyway it's only my 'expert' opinion based on the evidience you have provided and my experience in this field, if you don't want it then fine.
