Why does water drip under the car when the air conditioner is on in summer?

This is a normal phenomenon caused by condensation from the air conditioning system. Here is relevant information about car air conditioning: 1. Introduction to car air conditioning: The car air conditioning system (air-conditioning-device), commonly referred to as car AC, is designed to regulate and control the temperature, humidity, air cleanliness, and airflow within the vehicle cabin to optimal conditions. It provides a comfortable environment for passengers, reduces travel fatigue, and creates favorable working conditions for drivers, playing a crucial role in ensuring safe driving. 2. Components of car air conditioning: Generally includes cooling devices, heating devices, and ventilation systems. This integrated system makes full use of the limited space inside the vehicle, featuring a simple structure and easy operation, making it the internationally popular modern car air conditioning system.
It's quite common to see water dripping under the car when the air conditioning is on during summer, and in my opinion, there's no need to worry too much about it. During the cooling process, the AC system condenses moisture from the hot air inside the car, much like water droplets forming on the outside of a cold drink glass. This condensed water collects in a drain pan and is then expelled outside the vehicle through a drain tube. So, when it's hot outside, water dripping beneath the car is usually just a sign that the AC is working normally. However, if you notice an unusually large amount of water or no dripping at all, it might indicate a clogged drain tube—perhaps blocked by dust or leaves—which prevents the AC condensation from draining properly. This can lead to a damp interior and, over time, mold growth. I've experienced this myself and simply had the drain hole cleaned during a car wash to ensure it stays clear. Overall, checking the AC components during regular maintenance can help avoid these minor issues.
