I've been doing it for years as well as many many other HVAC techs have.
I don't know who the dumbass newb is but he obviously doesn't know what the fuck he's talking about.
Here's a 100%fact. It's a replacement. It is safe to use with the oil in an R-22 system. Wanna know how I can prove it? There's absolutely no possible way to remove all the oil from a system. The oil migrates throughout the entire system. To remove all the oil you would have to replace the evaporator coil, the condensing coil, the compressor, the accumulator and then flush the line set. If it's a heat pump there's still going to be residual oil in the tubing for the reversing valve and the valve itself. At that point you could have bought two 410A systems so why would they make a "replacement" refrigerant that's not compatible?
You didn't want to believe someone that has owned and operated an HVAC company since 93 but because it tickled your itch to take a jab at me you didn't even put a few digits in a search bar and click it. Try 407-C and then click search. Six little taps on a keyboard would have proved what I said.
I guess that's why you believe what the "spooks" said about this incident (when they have been proven liars). It tickles your Russia bad fantasy.
Go back to posting naked selfies. The adults are discussing topics with an open mind.
PS. I could have easily posted the link and told both of you to fuck off.
But I didn't.
