    Mobil TXV bulb Tane XE1000 Heat Pump

    Does anyone have any idea why a tech would take out txv bulb from inside the air handler unit, and mount it outside the unit on the suction line, claiming that it would help repair a problem of the heat pump not Dehumidifiing?

    In this case I was told that the coil on the inside air handler was dry and it was not suppose to be. That placing the TXV bulb outside the air handler in a new location would fix that problem.

    If this bulb is to blame is it letting too much Freon get in? or not enough Freon getting in?

    There was mention about moving the bulb to a warmer spot, Does that restrict the amount of freeon? or increases the flow? Why would the suction line be considered a "warmer" spot?

    The txv bulb normally sits on the internal part of the suction line does it not?

    grr...Trying to answer without being DIY

    Your evaporator when operating properly will help aide in the dehumidification of your house.

    In order to do that it must be evaporating properly. In order to do THAT it must have a properly operating metering device. Such as a txv. The bulb should be connected in the proper location, properly with proper insulation.. then checked for proper operation properly. ...by a properly licensed and properly competent proper technician, from a proper company. Properly.

    There are many places to mount the bulb and some places are better than others. The ultimate question is: Is it working properly in the new location?

    If you have time please take a look at TXV urgency.

    This is the phoenix metro area, do you know of proper tech? Better business organization and contractors licenses were clean on all these techs?

    I know it looks enjoyable taking my free time resorting to the internet talking with people I don't know and breathing in swamp cooling air.
