Somebody may have forgotten to properly reattach the condensation drain hose/tube

Shoddy work practices, it would seem

The heater core probably got messed up when the evaporator was replaced.

And now it’s leaking.

Is it water or coolant? That would indicate it is AC condensation (water) or a leak in the heater (coolant)

Coolant smells sweet. Blot some up with a paper towel, does it have any color?

In any case, the carpet will have to be removed and dried or you will have mold growing.
