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. Itâ€™s operating properly at this time. This job was covered under a part and labor warranty.
