Arrived and was shown mechanical thermostat that had failed. Customer bent metallic strip to force system to cool. Also has issues with airflow in living room, material in ductwork, ductwork collapsing, etc. Will provide estimate to replace thermostat to get customer by. Strongly recommend new equipment and new ductwork due to severe damage, animal feces, lack of insulation, and collapsing in areas. Recorded refrigerant pressures which show very low to no superheat due to poor airflow. This will damage aging compressor due to liquid flood back. Will submit info for install to reach out over new ducting for home.
