Does the car air conditioner drain water?

Car air conditioners do drain water. The drainage outlet of a car air conditioner is designed at the lowest point below the condenser in the cabin. The specific location varies depending on the car model, but you can find the drainage outlet by locating the condenser in the cabin. Below are some tips for air conditioner maintenance: 1. Comprehensive inspection of the air conditioner: When using the air conditioner for the first time in summer, you should first inspect the air conditioning system, such as checking the refrigerant and whether the air filter is too dirty through the liquid storage tank, and whether there are any foreign objects in the radiator. 2. Pay attention to cleaning the air conditioner: The air filter should be replaced regularly to prevent moldy smells from the air conditioner. Additionally, the condenser should also be cleaned periodically, and the radiator should be removed for thorough cleaning.
I used to drive older cars frequently, and air conditioning drainage was a common occurrence. In the summer, as soon as I turned on the AC, water would drip underneath the car. At first, I thought it was a leak in the engine compartment and rushed to the repair shop in a panic. The mechanic explained that when the AC cools, it absorbs moisture from the air, which condenses into water droplets and drains out through a small hole in the chassis—especially noticeable in high humidity or when idling. Now, I always check the ground for water marks after parking; if it's normal, I feel at ease. But if I notice water dripping onto the floor mats from inside the car, it's likely the drainage hole is clogged. Then, I use a thin stick to clear it out. Otherwise, trapped moisture can lead to mold and odors in the cabin, and the AC won’t cool effectively. A handy money-saving tip is to clean this hole during regular maintenance—it also adds peace of mind for driving safety.
