    This is always how it starts....so I have a friend of a friend who wants a 4 ton HP install. So my friend installed this unit for him. For some reason he thought that 13 seer hp's use r410a. So he fired up the system and added about 1/2 a pound of r410a before he notice that it's r22. Question is... what are the potental problem?????

    The entire refrigeration circuit will need to be replaced.

    I was told the mixture turns to a black tar-like substance.

    Not so fast,

    I remember seeing Jed Clampit, making alot of money from a black tar-like substance.

    jsin, you need to buy your friend a new unit.
    If you try to fail, and succeed.
    Which have you done ?

    Somebody lied to you.

    As posted, recover, change drier, vacuum, recharge.
    Perhaps you should have read the instructions before calling.

    benny, I was told the same thing at a 410a class. If the 2 mix it produces a nasty sludge in the bottom of the compressor which can result in failure.

    I think I remember something to this effect being said at the carrier puron class when the sheit first came out.
    To put the world in order, we must first put the nation in order; to put the nation in order, we must put the family in order; to put the family in order, we must cultivate our personal life; and to cultivate our personal life, we must first set our hearts right.

    Not to mention it is against Federal Law to mix refrigerants.

    Let me edit this a little:

    It is against Federal Law for us to mix refrigerants.

    The only way is to evacuate it into a properly labelled cylinder to be destroyed.

    Then evacuate and remove moisture, leak test, and recharge with R-22 only.

    The system should be able to live another life

    Of course, all of these have to be done by a certified contractor. Handling refrigerant is a serious business
