Is anyone using this R-22 drop in replacement for A/C? Opinions?

Saw it at the Comstar booth at OESP.

    Another one?

    Hi Paul.  The only ones I am aware of now is R 406&407C Ref, Which only 1 is a drop in.  I'd be interested to see additional choices..

    info

    It looks like RS-44 is a great alternative. Same cooling capacity at lower pressures equals lower energy costs. Here's some info I found online:

    I don't see a down side. Wondering if anyone is using this product.

    Forane R-427A

    We have recently done two replacements using Forane's R-427A. Temperature Glide is almost identical. Pressures are identical to 22. We decided to change the compressor oil to be safe. Took out Mineral Oil, went back with POE because I was concerned about oil return. Will check the oil in a month to look for carry over.



    I am paying special attention to these two to see how it works. I will keep you posted.



    I wish someone would just pick something and lets stick with it. I don't care what it is, just pick something. In a couple of years we are all going to be carrying around 10 different refrigerants to cover all the drop in replacements that we all tried.



    Just my $.02.
