The bare minimum basic repairs to get the system running today. Customer has 5 y/o Goodman heat pump that operates for basement level. Noticed during inspection that defrost control board was faulty and burnt on backside. Component would not operate in defrost mode, which potentially caused evaporator coil to freeze along with line set and outdoor unit, causing water in pan. Replaced defrost control board. Tested defrost mode. Recommend water protection upgrade. Biological growth presence. Recommend UV BlueTube to target and prevent biological growth. Condenser coil cleaning needed. Pressure levels were normal. Heat strips are operational. Replaced customer supplied 16x20x1 filter. System is currently working.
