..and they gave it names which they were obviously entitled to do, but they also either sold the product and it's name to the industry to which it applied or by federal law (based on what was the home country of the company that created it) had to give up rights to it AND the name and that's really the way it should be. Dupont has been performing way to much fellatio on the federal gov't for far to damned long if that's how it is for them & or for any industry in the United States & the world.

What you say may be true, but that's still pretty dumb. I haven't looked at prices for freon in over 10 years, but from what I remember it was going for about $50 a pound back in the day and at that time there was supposedly about 18 millions pounds of it left & federal law stated that all that had been made was the last of it, no new freon would be made & once it runs out that's it! Many companies over the last few hundred years created and patented products, chemicals, etc., ...

Thanks. I was beginning to feel like I was the only one that got that knee jerk reaction when hearing freon from even the most educated HVAC techs.

I feel your pain. I just go with the flow anymore but I will not say Freon. It reminds me of something I experienced when I moved to Texas 25 years ago. Many of the people I worked with would call Dr. Pepper "Coke", Dr. Pepper being the preferred soft drink. Hey! Y'all wanna' Coke? I learned.

It's been a LOT of years since I tested out for my EPA certification. Here's what I remember:Chlorofluoromethane = R12 (CFC)Chlorodifluoromethane = R22 (HCFC)Difluoromethane + Pentafluoroethane = R410a (HFC)R12 has a lifespan of 115 years in the atmosphere.R22 has a lifespan of 65 years in the atmosphere.Both are 'protected' by the very ozone they destroy... until air currents lift them into the upper atmosphere, where UV radiation breaks them down.

That's what I do.

well call it refrigerant, then figure out what type of refrigerant you need for your unit.

i hear ya, we've already started 410a for new installs anyways.

I'll buy NU-22 or MO-29 before I pay $350.

well ozone is only 6 miles away r 12 is a dichlorodiflouromethane so for every 1 chlorine atom destroys 100,000 o3 atoms.. well at least thats what the epa test book says |
