    Charging by superheat is a different game altogether and the correct superheat requirements can float between a vast range depending on the load on the indoor coil and the temperature outside. For example, one day the superheat requirements for a unit might be 5 degrees while another day on the same unit it might be 30 degrees. It depends entirely on the systems current operating conditions and can’t really be compared to a TXV system in the same way for this discussion.

    I'm tired of these mediocre "semi flammable" refrigerants. If we're going to do it let's do it right.
    Unless we change direction we are likely to end up where we are going.
