    What are the problems you mentioned?

    What is the service load?

    Is POCO transformer large enough for the load or is an undersized transformer contributing to voltage drop?

    Boosting voltage may only be a band-aid if there is problems with inadequate supply is what I am getting after with this line of questions and can be more problems down the road, especially if more load keeps getting added.
    I live for today, I'm just a day behind.

    VD issues

    The reading on the LCD display reads "LOW VOLTAGE" in running mode. The compressor seams to run fine but it still worries me.
