The pressure of R-410A is significantly higher than other refrigerants R-22 and R-404A. This does not mean that R-410A, or equipment containing R-410A is unsafe. It does mean that technicians must use AC equipment; cylinders and service tools have been re-engineered to handle these higher pressures.
