Customer called and said unit was blowing warm air. I went to the condenser and saw that some wires from the compressor were burnt. The hard start wires were also burnt. Added a new Hard Start and unit is cooling properly. Compressor is running high amps. Informed the customer that the unit is 19 years old and is working hard and may not be for much longer and to anticipate replacing system sooner than later. Collected $487.96
