    As far as the EPA is concerned, they don't recognize any refrigerants as drop-in substitutes.

    They lied to you. Not only is it wrong - what you describe is Doubly wrong.

    I paid extra for a 5/8 suction line on a 5 ton package. Mineral oil flows well with the hfc

    In situations like this, I always just think about what I would want.

    Not only is mixing gases irresponsible, it's not what I would want for my home system, and thus I won't do it.

    I work for a management company and a client is arguing that 422D can be used to top off R22 systems. I know its a general rule not to mix refrigerants and some say that its illegal. I've searched the EPA website and nothing about it being Illegal. I'm searching for something in writing....Government wise, that says its illegal so I can present to this client. Anybody come across anything in writing? Thanks

    It is illegal knowingly mix refrigerants.
    They cannot be separated
    There is no PT chart to follow for SH & SC readings
    You pay to dispose of it
    NO Refrigerant Manufacture allows it. All the retro fix papers state "Do Not Mix Refrigerants"

    I've always heard it's illegal to mix refrigerants, but I have never seen anything from the EPA site or any other site to confirm this. I would never personally condone mixing refrigerants, because I don't see how you would ever charge a system correctly, unless you have a chart for mixed refrigerants, or a crystal ball, and I don't have either.

    There was a thread on this a while back. I emailed the EPA and they said to not do it. Additionally, someone found a rule in the IMC that makes it against code to do so.

    if the freon leaks out, eventually, if you keep adding, you will flush out all the bad stuff and wind up with the good stuff.

    They said not to do it?
    Do you or anyone have a direct link to a rule on the EPA site, that directly addresses this? I did find this from the IMC.

    Thanks Marc! that will work!

    Edit: As I re-read this, it only says it would void the mfg. warranty. Well if you have a 20 year old system and your dropping in another refrigerant to top off the 22, there would probably be no warranty to worry about, right? This is very confusing for a only High School grad.

    If you mean this part:

    I think the warranty part would be a secondary concern. If the new blend has not gone through SNAP testing then according to the EPA it's prohibited for use.
