I was here to replace the compressor and add antifreeze to the loopfield. I sweated out the failed compressor and filter drier. I brazed in the new compressor and filter drier. Pressure tested system. Pulled unit in a vacuum and held at 300 microns. I added the factory charge of refrigerant to the system. Also added 10 gallons of anti freeze to the system. Cycled the geo. It’s operating properly at this time. This job was covered under a part and labor warranty.
