Upon my arrival I performed a 6 month checkup on 1 heat pump system. Flushed and treated the water removal system, installed new iFLO cartridge, reconnected iFLO to the WiFi, washed condenser coil using water, cleaned and treated the electrical cabinet with electrical insecticide then verified system safety and performance. Found that everything is operating to manufacture specifications at this time. Spoke with the customer about the drain line renovation of adding in a condensate pump. This is something they still plan to wait until next spring to move forward with.
