I was wondering, using a vintage AC unit, will one need to use the older, more costly Freon in order for it to function?? Have been told that the alledged compatible mix stuff out now basically can cause seizures of internals as the oils when mixed together are not truly compatible.. Now if a unit is completely uncharged, the newer 134 (I think is called) CAN be used, yes??? Thanks in advance.. __________________________________________________ Do You Yahoo!? Tired of spam?
