A friend of mine is a chemical engineer that lived through 40 years of these changes. He said it is NOT for the environment and never was. Twisted data on the effects of these chemicals was done deliberately. He said these changes keep the industry selling new equipment and the chemical companies like the one he was in management for, making new product.... He was very high up in a company you all would recognize. Our government is not what you think it is.

BINGO. Back when the Ozone problem was invented, R12 cost $1/lb in retail consumer sales. The stuff was used, as an example, for BB "machine guns" and to chill glassware for mixed drinks and so advertised on TV. Why so cheap? Off patent. Funny thing, the replacements were only manufactured when the maker paid a license fee.

How could the manufacture and disposal of all those POSSIBLY be better for the environment? "Efficiency?" If the new stuff is so much more efficient, how come 15,000BTU is still the max for a 15A circuit? You could get a 15K BTU window A/C that drew 13A in 1985. You'd think we'd at least be up to 18K BTU by now??

Ozone problem wasn't invented. A kind reminder that the CFC's were patented things that drove up the cost compared to the older non-patented refrigerants of the 30's like sulphur dioxide or.. r290. They banned those in favor of CFC's because they were safer - according to DuPont's lawyers. Anything they can patent and do. 1234yf is the new patented expensive stuff​. R290 or R600a at least isn't patented and I think R32 is also out of patent. @@GilmerJohn

Only thing that happened so far is at the compressor after cutting open the system I'll get a flame out. Just like a lighter flame.

They could add a pump down solenoid on the condenser liquid line. Leak sensor sends signal to air handler board, board sends 24v signal with extra wire to condenser. Solenoid closes and pumps down condenser. Compressor shuts off on low pressure switch. Only added 1 extra part and ran extra wire to condenser which usually there is spare wires already ran with the thermostat wire This will also prevent the whole loss of the refrigerant in the house. Refrigerant will be trapped between the compressor reed valves and the liquid line. Will only loose what is in the evaporator and suction line

Did after market automotive A/C yrs back and moved on to other things, so I did have my certificate for refrigerant handling etc,.. in the early 90's when 134a was fairly new to replace r12,there was a gas from a Chinese chemist called GU 2015. it was MORE efficient than 12 and was non cfc gas. Magic stuff. But 134 seemed to be the biggest thing on the market and Dow AND Dupont were cornering that market. We did buy some 2015 and used it for retrofits and customers were really happy with it. It was a straight replacement for 12. I heard of some shops replacing 12 with propane and I thought how crazy is that ?? Flammable refrigerant?? I bought a small window ac unit for my apt, and IT has flammable refrigerant. Crazy

Anyone that's not afraid of propane, to a reasonable extent, doesn't respect that it can absolutely do major harm. Not respecting that fact can lead to carelessness and a higher probability of a catastrophic event. I'm not saying no one should work with it but we should all give it the respect that it demands because it can 100% result in death and property damage. Everyone should have a certain amount of fear to preserve the respect it requires.

Here is some scientific information that should be taught: A2L laboratory testing was not within the stoichiometric combustion range of the A2L Gas. This gas is combustable in concentrations of less than 13% at room temperature and normal atmospheric pressures. See the MSDS: "Flammable gases, Category 1 Gases, which at 20°C (68°F) and a standard pressure of 101.3 kPa (14.7 psi): (a) are ignitable when in a mixture of 13% or less by volume in air; or (b) have a flammable range with air of at least 12 percentage points regardless of the lower flammable limit.

The part about not unsweating anything and to cut it out because of residual refrigerant in the lineset. Does this apply for example if I am changing a filter dryer, compressor or evap coil and I have the system recovered and shraders pulled and have nitrogen flowing? I would thing the nitrogen would have pushed any residual refrigerant out including displaced the oxygen to keep anything from igniting.

Packaged system (no line set), 12 feet away from combustibles, solar powered, can only be installed and serviced by those who are EPA608+A3++A2L certified who are also members of the local union authorized to perform such work, used to chill water (special water subject to a special tax), that can then be piped into an air handler (also only solar powered), which provides you to be compliant with upcoming 2026 cooling regulations …

Once again if you have a propane air condition or refrigeration and the unit is each outdoor I will implement a suction and liquid line solenoid together with a propane detector, a high and low pressure control will be required as normal wire into the system

It does seem like the most demanding industrial refrigeration settings tend to use flammable/hydrocarbon refrigerants... i think Dupont played up the dangers to get generations of Americans terrified of it so they could sell their proprietary, worse-performing HFC/FC refrigerants.

Genuinely curious if there's something I missed (hoping there's specifics behind this comment) what rules were rolled back under DTs EPA that helped small HVAC businesses? As far as I know, it was just stuff that helped massive corporations. Full disclosure, I'm a 12 year resi/comm/light ind electrician that genuinely hates all politicians equally. Talk me out of voting for RFK, go 😂

Asking the general population to vote for people that know even less about HVAC/R stuff than the general population may lead to disappointing results. Sucks when your industry doesn't get the same government subsidies as the green energy industry, which so happens to flip out over certain refrigerants.

Here is a scenario: split system with a gas pack in the basement below grade. The heat exchanger has small pinholes or small crack. Over 10 years of use the evaporator gets a very small leak so now the basement has the refrigerant in the basement air space along with combustion air for the burner and in the supply duct air through the small crack in the heat exchanger and the carbon monoxide alarm is no longer working after 10 years. What happens next?😮

The basic problem you speak of is that bureaucrats think in terms of Labels. it is either "flammable" or it is not. Nevermind that the woirld doesn't work that way.

Ozone depletion happens for the next couple decades due to the chlorine, global warming potential is how many times worse than CO2 it is for warming the atmosphere, but doesn't destroy the ozone layer which protects us from skin cancer etc. r410a is something like 2,200x worse than CO2 when it gets into the atmosphere but no Ozone depletion like R12 (worst) or R22.

With the propane refrigerant, I see chill water system will be a very big economic business. Instead of water, it will be coolant to compensate Big Freon charge equipment

Because of the anti-R12 histeria, most consumer aerosol cans use flammable propellants. Even/especially food products often use flammable propellants. Inhalers are much more expensive and dangerous. But that's OK.

I just can't get over the fact we could've skipped R410A altogether, and even by THEIR measure the environment would've been better off. It makes more sense to just go back to R-22 at this point, and we know it.
