Upon my arrival I connected to the air handler board via the Cool Cloud app. I found the outdoor unit was not set up correctly. I went through and set system to matched airflow for a 2 ton system and added 12oz refrigerant to obtain 6-8 degrees superheat and 20+ degree delta temperatures across the evaporator coil. I did increase the airflow by 300 cfm to help distribute the air to the upstairs as much as possible without diminishing the capacity of the system. I called installation manager to discuss my findings. Unit operating normal.
