    How frequent are you meant to do this? My three year old S4 is getting a bit smelly so probably time. What does an a/c service involve over and above a re-gas?

    I have to say that I am not really sure.

    Presumably, all joints/seals etc are checked, even if only visually,
    the system cleaned, re-gassed and filter changed.

    My understanding is that there is no such thing as
    a perfect seal, as light (as in not heavy) gases can escape molecule
    by molecule. If that is true then over 4 years or so
    a fair bit can leak away.

    If there is an expert out then who can add/put me
    straight I would be grateful.

    The system will leak gas over a perod and some get used.
    Manu recommend every 2 years and now recommend Anti bacterial agent run through the system after a year, well worth it.

    On a/c sevrice they should, that is should drain the gas, check for oil removed while doing so, evaquate the system 15 - 30 min, pulls out any moister and vacumn the system, regas put some leak dye in it and do a temp check. 10min
    they should look around for leaks or signs of dye too.
    I recommend replace pollen filter too as if your doing anti bac on evaporator best change filter other wise your just going to suck **** straight back in.
    Def worth doing I do mine every year, regass and antibac

    Cheap way....
    Go to halfrauds, buy a can of R134a and a can of Comma Air Con antiBac, then follow instructions on both products, this will regass and clean your air con, and save you over 100 quid.
