    Coil doesn't match outside unit, good luck getting it to perform correctly in both heat and cool.

    Heat pump TXVs have ball check valves in them & must be used with a heat pump application, plus be for the correct refrigerant & tonnage.

    If the conditioned space is around 50% relative humidity the temp-split is usually around 20-F; it would take a very high relative humidity level to drop the split to 12-F.

    Yes, the indoor coil must match the HP application.

    No way a 2012 HP will match a 2001 AC coil. It's never gonna work right until the coil is replaced with the correct model. The 2012 matching coil should have the correct TXV preinstalled.

    How about saving lots of speculation by giving us the model # of the coil?
