Re: R410A
said by HVACisCool :
R22 is old and will soon be illegal to purchase. It was replaced, mostly, by R134A.
Sorry thats incorrect, R12 was phased (taxed) out and replaced by R134a.
R22 is being replaced by 410A.

I apologize for the confusion. R134A is not a drop in replacement for R22. R410A isn't either. R407C is as close as it gets. Many manufacturers using R22 redesigned and then switched to R134A to avoid higher costs. My window unit runs R134A (8 years old). My central air runs R134A (6 years old).
HFO-1234yf (a flammable substance) will be replacing R134A in new automotive and other mobile A/C systems. Europe first, then North America. The systems are under much higher pressure. |

1234-yf isn't that different from a pressure point of view.
Comp output Pressure (Red is 1234yf - click for full size)
The real wild one is R-744 (CO2). It runs at pressures between 5 to 10 times higher than R134.
