Fundamentally, R1234YF systems will run at a slightly higher pressure, and the gas itself is actually flammable. Not super flammable, but it will burn slowly if you really tried to light it on fire (don’t). This means that all AC service shops will be slowly getting the new tools, machines, and training required to service R1234YF cars.At atmospheric pressure, the R134a has a boiling point of -26.8 o C and at 10psi pressure, its boiling point rises to -10.6 o C. If R134a is released into a room at atmospheric pressure and room temperature, it would instantly turn into gas. The temperature and pressure of the refrigerant have a direct relationship.
