Uppon my arrival found the evaporator coil completely frozen. I started the defrost process and changed all filters. I added 8.2 pounds of r410a refrigerant out of jug #179. I also used leak stop to try and seal up the leak. Customer said that she has someone come out one a year and add refrigerant to the system but hasn't got it done in a few years. I got my delta T to 21.1°. I found a weak capacitor on the od fan motor ( it's a 7.5 mfd reading 5.78). I recommend we keep monitoring the refrigerant levels and replace the run capacitor for OD fan motor. I put together an estimate and loaded my pictures to service titan and cleared the drain line. I left the unit in good working condition. The customer use the 25$ off coupon.
