    Hissing TXV

    I was up in the attic putting something away and heard a hissing noice coming from the TXV on my upstairs unit. The unit has an external sporlan(sp?) TXV....is that normal...never heard it before, what causes that?


    Thanks

    Is there any gurgling sounds?
    Possible low charge, or slight flow restriction (?)
    Is the system cooling up to spec's.

    Joe,

    If you are a technician, please apply for professional membership so that technical issues can be discussed in that forum. This forum is not where highly technical discussions should take place.
