    Sweaty R 22 Refrigerant lines

    Is it true that the suction line should be sweaty on a hot humid day?

    How much blood do I have to bathe in to get clean?

    Don't look down on anyone unless you're helping them up.

    If they are not sweaty and you are properly charged according to the chart on a hot summer day and the system seems to be not cooling would you charge until the ones get sweaty to compensate for the bad ductwork?

    Yeah that's what I told the homeowner which didn't go to well. So I had to walk away from the job. I guess I did the right thing

    How would bad/poor duct work cause the vapor line not to sweat?

    How many times must one fix something before it is fixed?

    If your return is sucking in 130 degree attic air the suction pressure will be so high that the saturated temp will be above the ambiant dew point.
