    Green tech guy.
    Supply company telling me you can add this on top of r-22, but most techs say it's a retrofit, any suggestions?

    Can be added with no TXV adjustment.

    Positively not! You seem to be saying that you will mix the refrigerants.
    The old refrigerant must be recovered and replaced with the new refrigerant.

    There = not here. Their = possessive pronoun. They're = they are
    It's = contraction of it is. Its = the possessive form of it
    Too = also. To = expressing motion. Two = 2
    Then = after that, next. Than = indicates a comparison.
    Questions should end with a question mark "?" Statements end with a period "."
