    I have a 13 SEER System W/410A refrigirant.
    Temp. diff. between ceiling reg. and return air is only 10 degrees.
    How can I determine if the TXV is working properly?
    The TXV bulb is placed outside the airhandler case with tape insulation.

    As for the TXV you can't. You will need to call a pro. Temps for the supply side should be taken near the evap, poorly insulated ducts in hot attics will give you a false temp.
