    I bought two 4 ton 16 seer 410a systems, each for a different customer. Why does the heat pump have an internally equalize TXV and the strait A/C have an externally equalize TXV? Any coil with a pressure drop and or a distributer should have a external TXV...Correct??

    Never seen an internally equalized TXV on residential HVAC equipment. What brand?
    If more government is the answer, then it's a really stupid question.

    If you were adding a TXV, yes you would be correct, but I suspect the mfg considered the pressure drop when they set the TXV up in the first place to take that into account.
