Very sorry to hear about your friend.

I don't think there are ANY of us in this discussion that have our priorities so jumbled that we consider the refrigerant you use as a life or death decision.

You are certainly correct. You have the right to use WHATEVER you wish in your a/c. If you wan't to fill it full of amonia, I say go for it!

We are simply pointing out the downside so that you are aware of the pros and cons. EVERYTHING is a compromise and there is no perfect situation. There are simply certain solutions that have more pros than cons or vice versa.

We are simply trying to help you understand the pros and cons. It is up to you to make the decision and it is up to you to live with whatever decision you make.

It is called personal responsibility. Unfortunately there are too many folks these days who want to make others take responsibility for their own bad decisions. In your case though, I'm sure that you are prepared to deal with the consequences, good or bad, of your own decisions.

Have a FANTASTIC day,
