Take a no cooling call 2 weeks ago to find a blown run capacitor. Replace Cap and check refrigerant charge only to find it 8 lbs low or R410a. Locate the leaks in the lower portion of the evap coil. Advise customer, Charge unit and order new coil. I go today to replace the coil that has been ordered for 2 weeks (the 1st one had been repaired at the factory and it was not pretty. I sent it back). As I am working I spotted the major Kink in the liquid line..... A factory Bend! Need a little QC!!
