There is a drain line on most auto air conditioners to drain water condensed from the air. When it gets blocked, water leaks into the floor. Have a mechanic put the car on a lift, and check the hose. You can usually clear it with a length of wire, or compressed air. If it smells like antifreeze, THAT would be the heater core leaking.
If it is leaking inside the car, the heater core has failed.If it is leaking inside the car, the heater core has failed.
It is okay if it leaks a bit of water outside but if it is leaking inside the house no it is not normal or okay.
