I got started by turning the system off at the thermostat and made my way to the air handler. I inspected multiple different components on the system, including the blower wheel/motor, evaporator coil, drain line, ductwork, electrical connections/components, etc. I checked all of these components for proper operation and cleanliness. As well as to make sure that nothing was damaged. I made my way to the outdoor unit. On the outdoor unit I inspected multiple different components as well, including electrical connections/components, Condenser fan motor, Compressor, Motor amp draws, Refrigerant pressures(good), And the outdoor unit coil(chemical cleaned). Other technical information is in my check sheet which I have emailed to the customer. only issues I found was that the capacitor I replaced last year had become weak again. I replaced it under the three-year maintenance warranty for the customer. I also found that the crank case heater was popping when getting in contact with water.
