Your coils froze up and you thawed them out when you shut the unit off. They will freeze up a while after running the AC again due to low freon most likely. If it's low it's probably leaking somewhere

The coils they are talking about are in your attic unit. They are really thin metal tubes and fins that get cold.
A fan pulls in air thru your return air filter, over the cold coils and out into your house.
Low freon with help from high humidity causes ice to form and grow to block the air passages thru and on the coil.
This prevents the air from getting the coldness from passing thru the coils and greatly decreases the volume of air too.
Running it in the fan only mode for 20-30 minutes usually melts the ice and you can get an hour or more of decent operation. Until it ices up again.
If your filter was real dirty, That can lower the air flow across the coils and contribute to the freezing issue. Dirty filters can also partially collapse allowing dust to coat the coils and further insulate the coils from the airflow.
When the coil is dirty, it must be cleaned along with having your freon at the right head pressure with unrestricted air flow allowing for the current temperature.
