After more research and talking to an ASE qualified A/C technician, he told me that what has happened is when our systems were worked on most likely the mechanics didn't put the system under a vacuum (or not long enough). Putting the system under a vacuum before introducing the freon into the system removes all moisture from the system. Moisture takes up space and freezes in the evaporator core which causes the condensation on the outside of the evaporator core to freeze as well. This causes the lack of airflow that were are experiencing. Unlike my work, hopefully yours is still under warranty. Hope this helps
