Is It Normal for a Car's Air Conditioning to Leak Water in Summer?

[LeColeman]

Whether the air conditioning leakage in a new car is a quality issue depends on the specific situation. It is normal for water to leak from external parts of the car, such as the exhaust pipe, when the air conditioning is on. This is condensation water from the air conditioning and does not harm the car or the air conditioning system. However, if water leaks inside the car, such as under the passenger seat, it indicates a problem that should be addressed at a car repair shop. Causes of car air conditioning water leakage: When the air conditioning is on, water dripping from the air conditioning drain tube under the car is normal; blockage of the evaporator housing drain pipe, causing water to overflow when the level is too high; cracks in the evaporator housing or loose drain pipes; poor insulation of the evaporator housing or cold air delivery pipes; extremely cold air causing condensation of moisture in the air at the vents, combined with continuous use of the outside air circulation function, leading to high-humidity outside air constantly entering the car and internal humidity not being discharged. Car air conditioning maintenance methods: Do not adjust the air vent direction randomly; start the air conditioning periodically in winter; avoid using the air conditioning for too long each time; ventilate and cool the car before turning on the air conditioning in summer, then switch to internal circulation; avoid prolonged use of the internal circulation mode. Generally, car air conditioning systems include cooling, heating, and ventilation devices. These integrated systems make full use of the limited space inside the car, featuring a simple structure and easy operation, making them the internationally popular modern car air conditioning system.
