I'm dubious about the freon costs, or at least about how much is due to treaties. http://www.carsurvey.org/viewcomments_review_25914.html says freon (r134) was $10/lb in 2002 - not $85. Ditto http://66.102.11.104/search?q=cache:gd4olrVxvHIJ:www.3di.com/gbof/downloads/success_stories/mat_res_waste20.pdf+freon+cost&hl=en
After reading http://www.thenewamerican.com/tna/1994/vo10no23.htm , I'm not sure what to believe. - Mpnolan 18:40, 14 Jan 2005 (UTC)

The List of Refrigerants mentions the word Freon only once. After looking through that article, I had no idea what a Freon was. With this page, at least the users will understand what the long list of chemicals represents. —Preceding unsigned comment added by Olego ( talk • contribs) 19:59, 14 July 2007
no one mentioned that this is a caustic gas
Freon is a brand name of halocarbon chemical compounds by DuPont. It is not a single substance and there are many products under that brand name. Although most are CFCs, not all are. Freon 23® is an HFC, therefore I changed the re-direct to refrigerant. See: http://www2.dupont.com/Refrigerants/en_US/products/Freon/Freon23.html Cantaloupe2 ( talk) 22:07, 3 April 2011 (UTC)
Freon is a registered trade name for DuPont halocarbon products. Every Freon contains fluorine and carbon. Some contains Chlorine as well. By definition CFCs mean chlorofluorocarbon and as not every Freon is a CFC, it is incorrect to do so. See my previous comment. Cantaloupe2 ( talk) 02:42, 17 August 2012 (UTC)
The article says moderately toxic. Not knowing the actual scale, I thought they were usually considered low toxicity. (Not counting oxygen displacement above, which it not toxicity, but loss of oxygen). Gah4 ( talk) 22:56, 23 May 2019 (UTC)
I have seen cans of R-134A from DuPont and Chemours that said "Freon" right on them. I suggest U edit first page to reflect this. 174.18.41.13 ( talk) 01:34, 25 May 2019 (UTC)
The introduction states that Freons are nonflammable. But Freon 40 is flammable, according to its introductory text. Could someone a bit better informed than me please revise the wording? 137.224.252.27 ( talk) 14:14, 2 March 2020 (UTC)
Is there a WP:RS that Freon is a generic trademark? Gah4 ( talk) 05:21, 1 May 2020 (UTC)
The lede paragraph says "These include the chlorofluorocarbons...". What does "these" refer to? What exactly is the relationship of Freon to CFCs - are they overlapping categories?
Also, I don't think we need the aside about acetone being used for nail varnish remover.
In the 80s, we dipped machine parts into vats of freon to clean them during maintenance. That's not a listed use so I thought I'd mention it. No idea when that started, sorry. 46.69.151.178 ( talk) 07:53, 12 January 2023 (UTC)
The article mixed HFC and HCFC, so pick one! Gah4 ( talk) 23:53, 21 May 2023 (UTC)
