Complete warranty evaporator coil replacement. I found the system almost empty of refrigerant when I got on site. I informed the customer we will have to add (7) lbs of 410a to the system after the repair is made. I removed the old coil and replaced with the new OEM coil. After brazing the line-set back into the system I performed a pressure test to 350 psi to ensure no leaks. I also performed a vacuum test to ensure a clean line-set. A new filter drier was not needed on this repair as the existing filter drier is located in the condenser where the remaining refrigerant was locked out at. I added (7) lbs of refrigerant to the system and started the system up. Cycle and inspect equipment. Left system in good working order.
