    Question Coolant Line problems


    My Brother-in-law updated his house to a larger system and was kind enough to give me his old system for my place in the country.
    I'm usually pretty good at DIY, but have hit a snag.

    Problem is, the coolant line was chopped off the the evaporator coil w/o any tubing to play with (condensing coil has plenty tubing still attached)and now I need to (for lack of a better phrase) de-solder the joint. I've tried MAPP and had no luck. If I have to cut as close to the joint as possible and clean it up, I'll have about 3/4" to play with. Will that be enough? Any suggestions would be very much appreciated.

    Thanks go out to This Old House for this board.

    And thanks to all.

    MAPP is for copper house plumbing, not for A/C.

    Call a certified A/C contractor for this job, he would have the right equipment and knowledge how to do it safely.

    BTW, coolant is used in car radiators. Freon is used in A/Cs.

    Freon is the Dupont trade name More accurately it's called Refrigerant.

    HEllo, Other than transmission fluid issue, another possibility could be engine oil mixing with the coolant due to a faulty intake or head gasket!
