for the past 4/6 weeks my aircon makes a very strange sound
i would say it sounds like a lousd hisss with a rattle (to hard to decsribe the sound) when its on
now the coldness is no worse it may be a little less colder but not by alot so seems to be working fine

my guess is i need a re-gas just wondering if anyone else has had the same symptons and if so what the outcome was

cheers Baz
