Arrived on site for black stuff shooting out of unit. The black stuff shooting out of the ductless unit is bacterial Growth. Sprayed non rinse evaporator cleaner on coils. Inform the customer that the bacterial growth is coming from the blower wheel. Inform them that we need to take the blower wheel out of the system which is a several hour work to appropriately try to get rid of the growth. Customer did state that they have no issues with Cooling so unit is working fine aside from having bacterial growth. Used a diluted chemical and cleaning wipes to get rid of the growth on the lip of the unit the best that I could.
