He's doing my new install, brazed the lines, charged with nitrogen, found a leak where the txv connected to the suction line in the evap? Tightened that, then it held at 350psi overnight. Said all is good. But from what I've read here 410a can be much higher pressure on the liquid side.. should he have pressure tested higher? thanks, Mike
