Upon my arrival I evaluated 1 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 the voltage enhancement system for the outdoor unit low, customer declined replacing it at this time. I also found zooglea in the primary drain line, recommended iFlo , customer declined at this time. She did request that the quotes be sent to her email.
