    Hmm

    Does a TXV bulb need to be insulated if it is inside the plenum on the outlet of the evaporator?? I have a new replacement that has low cooling and the unit runs all the time. I spoke of this unit in a post earlier today but didn,t get but 1 reply...lol. If I add r22 to system or take it out my suction pressure stays at 75 pounds. Could the problem be that the bulb is not insulated, it came from the factory like that, should it be insulated?? This is a Tempstar coil.

    Plentum coil I am guessing, but my answer is still no, outside the box yes definitely.

    Give more info, and you might get answers to what is wrong with your system.

    First what is the complaint.

    Next, indoor wb, and out dorr db.

    Suction pressure and suction line temp.

    liquid line pressure and temp.

    And coil delta.

    If it was stuck open the suction would move for sure, a TXV will keep the pressures more in line so it's not unusual your suction is not just jumping up and down by adding or removing a little freon.
