news I'm in the market to replace my split-system heat pump A/C. An installer
came by today and said that there is a "new r22" that eliminates the need
for the expensive puron (r410). I googled and couldn't find anything about
this "new r22". Has anyone read anything about it?

I have not priced it lately, but just how much could the more expensive r401
be ? There are only several pounds in a system.

I did replace my system about 3 years ago and went with the r-22. My
thinking is that it operates at lower pressure and has been around long
enough to have the bugs worked out of the system. I also had most of a
bottle of that gas left from years ago.
If I need to add some, I can do that .
