Upon arriving indoor and outdoor unit was not running. Thermostat was blank. I found a high voltage wire, going into the air handler. One leg of the wiring had burnt and separated. Additionally, 12 gauge wire was being utilized going from the disconnect to the AirHandler. The blower motor was over excessively impacted with growth as well as the interior of the cabinet. Customer decided to go with the Band-Aid repair option of replacing the high voltage wire and wish to forgo any type of cleaning or pure air. UV protection inside the unit as the customer is planning on purchasing a new unit by January 2025.
