My air con is working perfectly fine at the moment (hope I dont curse it saying that!) but was wondering how much longer it'll last. My car has 93k on the clock and full service history but no mention of any work being done on the air con system. Is it worth taking it to my local honda dealer and paying them the £60 they want to do an air con service or is there something I can do myself? I know I cant re-gas it but is there more to it?
