    404a in a 408 system

    A friend of mine just charged 404 into a system that had no nameplate and was going on info that was provided to him by a worker at the store he was at. it now appears that it may have been a 408 system. Question is, will 404 work with ab oil?

    Just because they are only 4 numbers away from each other,does not mean they are almost the same!

    good,that's what I told him, and advised him to pull the charge and replace with 408. I am not a low temp man but I knew there would be some at this site.
