It’s the scariest moment of the year for many homeowners – that first really hot day, usually in May, when we turn on our air conditioners for the first time since the previous summer and cross our fingers that it still works.
If not, it will need to be repaired or possibly replaced, and the 2022 air conditioning season is shaping up to be a very expensive one thanks to environmental regulations. Meanwhile, the Senate is busy considering a United Nations climate treaty called the Kigali Amendment that would make things worse.
The news is bad whether your air conditioner is old or new. Most pre-2010 units were designed to use a refrigerant called R-22 that isn’t made anymore – the Environmental Protection Agency banned further production in 2020 over its contribution to depleting the earth’s ozone layer. Those needing to replace R-22 lost from a leak will have to pay hundreds more for this common repair.
More than half the systems are newer ones using a refrigerant called R-410A. Though initially hailed as an ozone-friendly improvement over R-22 (it was even trademarked "Puron"), R-410A subsequently came under attack as a contributor to climate change. In December 2020, Congress slipped production caps on it and similar refrigerants into a big must-pass spending package. EPA launched its rationing program on January 1st of this year, and the wholesale price of R-410A has already jumped 4-fold over pre-regulation levels to around $20 per pound and at least twice that retail. Systems typically need eight to 15 pounds.
Thus, 2022 will be the first summer where virtually every one of the nation’s 100 million residential central air conditioners relies on a refrigerant in short supply, thanks to federal environmental measures.

If you were to put a flame to the old r12 you would end up with mustard gas. S’all I’m sayin’. No more, no less.
Not chemically possible.
Show me how you get mustard gas bis(2-chloroethyl) sulfide (C₄H₈Cl₂S) from R-12 Dichlorodifluoromethane (CCl2F2) while pulling R-12 vapor through a hose into a burning propane (C₃H₈) flame.
“…… due to its singular chemical profile, phosgene exposure remained a silent killer when dealing with such 20th-century refrigerants as R-11, R-12, R-113, and R-114. Containing two chlorine atoms and one oxygen atom, phosgene forms when chlorinated hydrocarbon compounds are exposed to high temperatures. These compounds contain chlorine, hydrogen, and carbon, and they become toxic when exposed to high temperatures, such as when checking for leaks.”
Non sequitur. You made the claim in post #81 that R-12, when exposed to a flame, results in mustard gas. Prove it or leave me be.
Ok, now I get it. You are quibbling over phosgene vs mustard gas. You are playing “choose your poison”. For the purposes of this rapidly deteriorating conversation, it seemed that we were equating mustard gas, phosgene and nerve gas. In your post#77 you stated, “Phosgene gas was a particularly nasty weapon used by the Germans in WW1 and has absolutely nothing to do with R-12 ………….” You have been busy backpedaling from that statement. So here we are with you making false claims about phosgene, and me apparently making a false claim about “mustard gas” (I should have said phosgene). Live and learn.
Whatever dude. You’re flip flopping like a fish outta water. Backpedaling seems to be your forte as you can’t make up your mind whether it’s phosgene gas, mustard gas, or nerve gas with respect to R-12 and an open flame, specifically propane.
Gotta a lot of nerve accusing someone of that which you yourself are guilty of..... pedaling misinformation. Obviously facts, rational thought, and logic are not in your skill set with respect to this topic. Since you’re not interested in facts nor the truth, we have nothing left to say other than to agree to disagree.
As an aside, my coworkers refer to me as Mr. A/C.
Sure, you can try to spin it like that. But the fact is I backed off my “mustard gas from heating r12 with a flame” and (due to my own research and no thanks to you, Mr A/C) changed it to “phosgene from heating R12 with a flame”. I guess you missed that in my last post. You’d like to saunter off with a simple ‘agree to disagree’? Don’t you feel obligated to clean up your claim that “phosgene …has absolutely nothing to do with R12”? Don’t you realize, that when you used your antiquated propane leak detector and the flame turned blue/green you were making phosgene gas?
Other than that, keep up the good work.
I live in a no-spin zone by choice. You ought to try it sometime as you’re less likely to end up dizzy or stuck in circular reasoning. Don’t know why I keep trying to get it through your thick skull. Maybe I’m a glutton for punishment so I’ll give it another go.
Get out a piece of paper and a pencil and show me how you can chemically arrive at phosgene gas (COCl2) from a R-12 Dichlorodifluoromethane (CCl2F2) gas while pulling said R-12 gas through a 1/4” ID 2’ foot length hose into and through a burning propane (C₃H₈) flame. Show your work.
Answer is: it’s chemically impossible but try it anyway just for fun. I suppose you’ll move on to nerve gas (or some version thereof) next because that’s the only one(s) left for you to carry on about. Give it up as you obviously know absolutely nothing about chemistry (or don’t want to know). In addition, work on your reading comprehension, logic, and reasoning skills as it will get you further in life than believing the massive amounts of misinformation on the inter-web.
You are becoming redundant, which forces me to be redundant. But I have my limits.
Any danged fool knows that a Halide detector will not produce phosgene, mustard, or nerve gases of any kind. The appearance of the greenish flame is the chlorine in the R-12 reacting with the propane flame which allows one to determine the leak location in the A/C system. No copper disc in this unit. Squawk all ya want about phosgene but you’re just flat out wrong about the Halide detector. Wiki..... really? Wiki’s chock full of misinformation but since you’re relying on it: “No valid statistics are available...”, therefore no valid data. Well informed for years of the various methods of leak detection so there’s nothing you can say that I don’t already know.
I’ll choose redundant any day of the week over obtuse. Now, away with you as my patience has worn thin from your nonsense. I’ll not engage you any further as neither of us are budging from our position and I’m fairly certain the last word will be yours.... LOL.
