"James Robinson" wrote In fact, commercial production of chemicals like carbon tetrachloride, trichlorethane, and certain types of Freon have ceased by international agreement. Freon is not a VOC, is it? Certain types of Freon are. Those types are no longer used in new air conditioning or refrigeration systems. Older systems will still have them, but you can't replace lost fluid if you have a leak. |

Not with the older type of fluid, but you can replace it with the newer types. George Patterson Drink is the curse of the land. It makes you quarrel with your neighbor. It makes you shoot at your landlord. And it makes you miss him. |

Sure, they are nasty things, in how they combine in the upper atmosphere to eat ozone, but VOC's are things that burn, and were not burned before they were released, right? It all just has to do with classifications, and I believe Freon is in a different classification. -- Jim in NC |

Volatile Organic Compounds do not have to burn. They simply evaporate quickly, and can change chemically under the effects of sunlight. It all just has to do with classifications, and I believe Freon is in a different classification. It may simply be classification, but the EPA considers certain types of Freon to be VOCs. Here is a link to a couple of web sites that list VOCs, including various types of Freon as examples: http://www.skcinc.com/cff/1676.pdf http://www.airquality.lanl.gov/pdf/N...dVOCTable3.pdf |

That must have been nonexistium that the AC technician put in my AC at home this spring. G The old stuff is still available, but it costs more than the new stuff, and must be used by licensed tecs, and must be pumped out and recovered when conditions demand that it be removed from the system. I think I heard that the old stuff is not being manufactured anymore, but that the existing stockpiles will last for a few more years, but I'm not at all sure about that. -- Jim in NC |

I assumed it was gone by now. They stopped making CFC-12 about 10 years ago, and the only stocks were from what was drained from existing cars, plus whatever stocks where in place when production ended. You can also replace CFC-12 with other types of Freon. (like HFC-134a) The replacements aren't quite as effective in older systems as CFC-12. |
