Understood. The air conditioning system is only supposed to lower air temperature about 20 degrees. The real comfort comes from removing the humidity from the air. That moisture condenses on the cold evaporator in the dash. In fact, the system is designed to never get colder than 40 degrees because that moisture will freeze into a block of ice and block air flow.
The water drips into a drain pan just a like a home dehumidifier fills a bucket. That water drips from in front of the firewall onto the ground. The most common problem is that drain tube gets plugged with leaves and other debris. The water builds up and will slosh onto the passenger side floor when you go around a corner. Typically the fix is to squeeze the rubber tube that is hanging down from the firewall to open up the slotted end. If that doesn't dislodge the blockage, the hose can be removed so you can poke a pencil into the tube to clear any debris. In less severe cases, you might get a musty smell.
Now that I shared all that, rest assured the water dripping onto the ground is proof your system is working properly.
