Is It Normal for a Car to Leak Water When the Air Conditioning Is On?

Whether it is normal for a car to leak water when the air conditioning is on depends on the situation. It is normal for water to leak from the car's exterior, such as the exhaust pipe, when the air conditioning is running. This is condensation water from the air conditioning system and will not harm the car or the air conditioning. However, if water leaks inside the car, such as under the passenger seat, there is a problem, and the car should be taken to an auto repair shop for servicing. The car air conditioning system, abbreviated as car AC, is used to adjust and control the temperature, humidity, air cleanliness, and air flow inside the car cabin to a suitable state, providing a comfortable riding environment for passengers and reducing travel fatigue. It also creates good working conditions for the driver and plays an important role in ensuring safe driving as a ventilation device.
Whether a car leaking water when the AC is on is normal depends on the situation. If water drips from underneath the car chassis, it's completely normal. This happens because when the AC cools, moisture from the air condenses on the evaporator, and this water is drained outside the car through a dedicated drain pipe. The more humid the weather, the more water will drip. I once saw a puddle under my car in a parking lot and panicked at first, but later learned there's no need to worry as long as the water isn't leaking inside the car. Just remember not to place floor mats or carpets near the drain outlet, as they can block the drain pipe. However, if the AC water leaks inside the car, like if the passenger side footwell gets wet, you should be alarmed. This is usually caused by a blocked or broken drain pipe and needs immediate attention to prevent damage to the carpet and electrical circuits.
