Luckily I haven't had a car that needed it yet, but sooner than later it's inevitable. It's been out probably 8 years now and still costs nearly $60 a pound while I paid less than $3 per pound for 134a last year by the drum.
DuPont still has the patent, hence they have the price set.I've wondered the same thing. All I can figure is Dupont or whoever still holds some sort of a license or patent on the formula.
Dupont/Chemours doesnt own the patent. Honeywell does. Honeywell licenses the patent to Chemours because they worked together on the development. 45-50 bucks a pound is the projected floor based on the cost of materials to make the refrigerant. The raw materials are a fair bit more expensive than 134aDuPont still has the patent, hence they have the price set.
Thanks for the clarification. I was going off of what everyone has told me. I just know people at my work constantly complain about the price jump like it is my fault.Dupont/Chemours doesnt own the patent. Honeywell does.

You can pick up a can of AC Pro R1234yf at autozone. Not cheap, $135, but it’s available. If you have hoses you can get an 8oz can for $45. As for what you’re talking about, it’s quantities over 2lbs that you need the certification.I am wondering how you get this anyway? I can get it because I’m certified, I was told for the R1234YF you have to have the certification to get any or put any in cars. Are you certified? Maybe it’s just for the larger amount quantities that you have to be certified? I haven’t had to get any yet the only car we have that takes it is the 2017 Camry and hasn’t needed the A/C service yet.
R744 aka CO2 runs at significantly higher pressures. From Emerson, a high temperature evaporator used for chilled food will run at a pressure of about 363psi to 435psi, the high side is even higher. I wouldn’t want to be anywhere near that system in the event of an accident.It would be nice if we didn't continually invent new/dangerous refrigerants and just use R744.
We could always just mandate that it be recovered from the air and not created anew.
Are the gauges different from the home a/c r-22 gauges with adapters that i use for r-134a?There are many people with the R1234yf systems converting them to R134a w/o issue. Hopefully when the time comes for me to service my Wrangler the price will come down. I already have the gauges and hoses for R1234yf. Honeywell is going to milk that cash cow as long as they can.
If you have the card that has you certified for 134a you are certified for this too.I was told for the R1234YF you have to have the certification to get any or put any in cars.
I bought these adapters that work with my 134a gauges. Haven't used them yet though.Are the gauges different from the home a/c r-22 gauges with adapters that i use for r-134a?
Yes, the can tap is reverse threaded and they use different adapters to make the connections to the high and low side of the system. Having said that Mastercool makes a set that works with R134a and R1234yf, so you could probably use a R134a set with the proper can tap and couplers. I got a good deal on Yellow Jacket a while back on Ebay which was too good to pass on.Are the gauges different from the home a/c r-22 gauges with adapters that i use for r-134a?

Thanks guys! S o maybe the hi lo side r134a couplers fit, i just need the can tap to connect to my gauge set.Yes, the can tap is reverse threaded and they use different adapters to make the connections to the high and low side of the system.

No they wont. That's why I bought those adapters.Thanks guys! S o maybe the hi lo side r134a couplers fit, i just need the can tap to connect to my gauge set.
So i need all three, port adapters and the can tap. Thanks.No they wont. That's why I bought those adapters.
