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 that the voltage distribution system has burnt contacts, I also found that the airflow distribution system was dirty, using the electronic leak detector I found the leaks at the indoor coil Recommended an appointment with the comfort advisor but Louise declined that option at this time. I’ll send an estimate to replace the indoor heat exchanger. I’ll also send estimates for the cleaning of the indoor unit and the voltage distribution system. Louise would like the estimates and invoice mailed to her at this time. Due to the age of the system I would highly recommend setting up an appointment with the comfort advisor before selecting a repair option.
