AC performance tuneup times two systems. Client had already changed the filters by the time we got here. Inspect blowers, evaporators and ductwork. Downstairs evaporator coil has a small fracture in it. I added 2 pounds of 410 A to correct the charge today. I am leaving an estimate for replacement coil, the leaks do not get any better. They only get worse. Capacitors in contactors. Changed out upstairs run capacitor on the condenser. Washed both condenser coils. Systems are cooling at manufacturer specs at this time.,
