So I have a Goodman ARUF363616 system that was installed horizontal and in my attic. When I would turn the unit on it would cool excellent and the air force could be heard. After about 30 minutes the a-coils would freeze thus the air force was reduced. Hvac person checked freon level and it was good. I cleaned the a-coils very well, the filter is brand new, I installed a new blower motor, new transformer, new computer board, and new capacitor. All ducts are open and cleaned, no blockage of any kind. .. I am so confused as to what the problem is. I understand the icing over restricts the air flow thus the airflow becomes restricted and noise is quieter. The company that installed this unit obviously didn't send out a tech. that wanted to troubleshoot the problem deeper. I really need some help
