Elgin Ac repair Upon my arrival I evaluated 1 carrier heat pump system. I verified system safety and performance is to manufacture specifications. Flushed and treated the water removal system. Cleaned the electrical cabinet and washed unit using water. Found bacterial growth inside air handler, on air movement system, and on air movement system wire harness. Recommend installing Solaris UV bacterial prevention. Customer wants options emailed over to him along with pictures of growth. System heating properly at this time
