What kind of hissing are you people talking about ?
The TXvalve is designed to HISS.... it is spraying liquid refrigerant into the inside of the evaporator ... this is THE PHASE CHANGE which is HOW the AC works.....
Are any of you suggesting the hissing is releasing refrigerant into the Atmosphere ?
That is not supposed to happen...
