Foe this job I came to replace the condensing coil as well as the compressor on the customers straight cool system. I removed the old coil and compressor, brazed in the new compressor first followed by the condensing coil. After doing all that I resembled the unit and pulled a vacuum and purged with nitrogen where I was able to get the system to 375 microns indicating that a vast majority of contaminants or removed from the system as well as the line set. I charge the system to a 9° sub cool in the system was producing a 21° split.
