Upon arrival i found no refrigerant in system. I pressurized system and found capillary tube covered in some kind of corrosion. The pan was full of it. Then i noticed some kind of big pan treatment on top of coil. When it melted from condensation it ran down coil and built up in corners of pan and looks like it eroded capillary tube. I quoted coil and discussed with homeowner on multiple phone calls. I could not collect because she had to hang up for important call.
