Complete member tune up. Change customer supplied filter. Inspect electrical components. Test amps and volts. Delta t measures at 12 degrees. Ensure system is running in both heating and cooling modes. Clear out drain line with vacuum. A picture of the evaporator coil was uploaded into ST. At condenser checked pressures, temps, amps and volts. Dual run capacitor was failed. I replaced with a turbo 200 capacitor that has a 5 year warranty. I also installed a surge protector to protect the condenser against power surges. The unit was low on refrigerant. I completed a leak search and could not pinpoint the leak. The leak may be underground in the line-set that was poured over. The customer wants to wait a few weeks and have a tech return to see how slow the leak is. If the refrigerant is leaking at a fast rate we will perform an isolation test under the same leak search that was paid for. I added (4) lbs of 410a refrigerant. System is in working order.
