Upon my arrival I performed the approved repairs for the refrigerant leak at the refrigerant pressure control bypass tube. I recovered all refrigerant from the system, flowed nitrogen while brazing, fixed the leak at the bypass tube, installed new inline filter dryer closest to the indoor unit, installed new piece of copper where old filter dryer was located, pressure tested the system to 360psi with nitrogen, evacuated nitrogen after pressure test was shown to be tight, brought the system down to a proper vacuum and while in the process performed a triple evacuation service by breaking vacuum 3 times with nitrogen to insure no moisture is present within the system, once I obtained the proper vacuum below 500 microns I recharged the system with 12lbs of r410a refrigerant. I then ran a performance and safety testing checking pressures and amp draws. After verifying pressures were could I pumped the system down and installed acid preventatives for a longer compressor life. System calls f
