What happens when evaporator coils are dirty?
An extremely dirty evaporator coil can cause your AC to breakdown completely. This happens when condensation forms on the dirt and then freezes during the AC’s operation. The buildup of frost stops the heat transfer with the air in your home, which causes the air conditioner to stop cooling air at all.
What happens if AC evaporator is clogged?
When the inside of the evaporator is clogged with debris, it causes an inconsistent flow of the air into the vents. The inside of the vehicle is developing a bad smell: Since the evaporator is located between the dashboard and the firewall, it can develop a bad smell when it’s clogged with excess bacteria and debris.

But if the water dripping from the coil contains dirt, this will become lodged in the drain, eventually creating a complete clog.
Can a dirty blower fan cause coil icing?
titled DIRTY A/C BLOWERS. This article describes the very significant reduction in airflow across a cooling coil that can occur if the squirrel cage fan blades are dirty on the blower fan in the air handler.
